How I Picked and Tested the Best Natural Dishwasher Soaps

To find the most effective natural detergent, I started by researching 20 of the most popular and highly-rated eco-friendly dishwasher detergents on the market. From there, I narrowed the list down to 5 top contenders based on their ingredient transparency, positive user reviews, brand reputation for sustainability, and third-party certifications. I then purchased each one and put them through rigorous, real-world testing in my own dishwasher for over a month.

My evaluation process was built on a foundation of proven results and expert-reviewed criteria. Here are the key factors I used to compare each product:

1. Cleaning Performance: I tested each detergent on a variety of tough, everyday messes. This included 48-hour dried-on oatmeal, baked-on lasagna, greasy pans, and heavy stains from coffee and red wine to see how effectively the science-backed formulas worked.
2. Residue & Spotting: I paid close attention to whether the soap left dishes, glassware, and cutlery sparkling and free of film or water spots. This was especially important as I have moderately hard water, a common cause of cloudy glasses.
3. Eco-Credentials & Ingredients: I did a deep dive into each ingredient list, prioritizing plant-based, biodegradable, and non-toxic formulas. I gave extra points for trusted third-party seals like EPA Safer Choice, Leaping Bunny (cruelty-free), and USDA Biobased Product.
4. Packaging Sustainability: My goal was to find products that are serious about reducing plastic. I evaluated each brand’s commitment to zero-waste, plastic-free, recyclable, or compostable packaging.
5. Ease of Use: I assessed the overall convenience of the format. I considered how easy it was to handle and dispense the tablets, pods, or liquid during a standard dishwasher cycle without mess or confusion.
6. Value: I considered the overall balance of cleaning performance, ingredient quality, and the number of washes per package to determine the product’s value within its price category. I wasn’t looking for the cheapest, but the one that offered the best results for the cost.

My 2026 Eco-Friendly Dishwasher Soap Reviews

Here are my detailed, hands-on reviews of the five best eco-friendly dishwasher soaps. I’ve broken down what I liked, what could be improved, and my personal experience with each one to help you find the perfect match for your home.

Best Overall: Blueland Plastic-Free Tablets Review

The Blueland Plastic-Free Dishwasher Detergent Tablets quickly became my top choice for any household looking for maximum cleaning power without a shred of plastic waste. During my testing, I found these tablets to be the most consistently powerful, especially on tough, baked-on food that other natural detergents simply couldn’t handle. They are the definition of an eco-friendly product that makes zero compromises on performance.

Specifications:
* Form: Naked Tablet
* Count: 60 Tablets
* Key Feature: 2x Enzyme Power for 48-hr baked-on food
* Packaging: 100% Plastic-Free, Compostable Pouch & Refillable Tin
* Certifications: EPA Safer Choice, Leaping Bunny Cruelty-Free, B Corp Certified, Climate Neutral, USDA Bio-Preferred

Pros: What I Liked
* ✅ Exceptional Cleaning Power: The 2x enzyme formula is not just marketing hype. It truly impressed me by cutting through dried-on oatmeal and stubborn coffee stains on the first try, which other detergents struggled with.
* ✅ 100% Plastic-Free: This is what zero-waste dreams are made of. I absolutely love that there is zero plastic, not even the dissolvable PVA film found on most pods. You simply drop the “naked” tablet directly into the dispenser.
* ✅ Crystal Clear Results: My glassware consistently came out sparkling clean without any cloudy film or spots. This was a huge win, as it performed beautifully even in my home’s moderately hard water.
* ✅ Top-Tier Certifications: The comprehensive list of certifications—including EPA Safer Choice, B Corp, Leaping Bunny, and Climate Neutral—gives me immense confidence in the product’s safety, ethical production, and environmental claims.
* ✅ Septic-Safe & Clean Ingredients: The microplastic-free formula is made with plant and mineral-based ingredients, making it safe for my home’s septic system and for use around my family.
* ✅ Incredibly Easy to Use: There’s no unwrapping or mess. Just take one tablet and place it in the dispenser. It’s the simplest and cleanest process I’ve tested.

Cons: What Could Be Improved
* ❌ Slightly Brittle Tablets: Because the tablets are completely unwrapped to avoid PVA, a few at the bottom of the compostable bag were broken or crumbled. Workaround: This was a minor issue, as the broken pieces and powder still cleaned perfectly when I poured them into the dispenser.
* ❌ Premium Positioning: This is a premium-priced product. The cost-per-wash is higher than some other options, but it reflects the high-quality ingredients, powerful formula, and true plastic-free mission.
* ❌ Requires Dry Hands: You must handle the tablets with dry hands to prevent them from starting to dissolve before the wash cycle begins. This is a small habit change but worth noting.

My Experience

Cleaning Performance & Enzyme Power: My ultimate test for any dishwasher detergent is a lasagna pan left out for a day or two. The Blueland tablets removed nearly every bit of baked-on cheese and sauce on a normal cycle, which was incredibly impressive. The dual-enzyme action is noticeably more powerful than many other eco-friendly options I’ve used in the past. It consistently delivered a deep clean on full loads.

Eco-Credentials & Certifications: Blueland’s commitment to sustainability is second to none. The combination of being a B Corp, Climate Neutral, and EPA Safer Choice certified brand shows a profound dedication that goes far beyond just the ingredients. This isn’t greenwashing; it’s a core part of their identity, which I find very trustworthy.

Packaging & Usability: The user experience is fantastic. Dropping a simple, unwrapped tablet in the dispenser is unbelievably easy. My initial purchase came with a stylish and reusable “forever tin” for storage, which is a brilliant touch for reducing counter clutter and eliminating future packaging waste. This is the gold standard for sustainable design in home cleaning.

Best for Sensitive Skin: Seventh Generation Free & Clear Packs Review

The Seventh Generation Free & Clear Dishwasher Detergent Packs are my top recommendation for any household needing a powerful clean without any added fragrances, dyes, or harsh chemicals. It’s the ideal solution for families with sensitive skin, allergies, or anyone who simply can’t stand the artificial chemical smell left behind by conventional detergents. It proves you can have a gentle formula that still packs a punch against grease.

Specifications:
* Form: Pack (Pod with PVA film)
* Count: 72 Packs
* Key Feature: Free of fragrances, dyes, phosphates, and chlorine bleach
* Packaging: 90% Plastic-Free Packaging (Recycled Cardboard Box)
* Certifications: USDA Certified Biobased Product (79%)

Pros: What I Liked
* ✅ Truly Fragrance-Free: This is the biggest win for me. After a full cycle, my dishwasher and dishes had absolutely no chemical or artificial scent. They just smelled neutral and clean.
* ✅ Tough on Grease: The enzyme-rich formula did an excellent job cutting through greasy residue. I tested it on plates after a bacon-and-egg breakfast, and it left them perfectly clean without needing a pre-rinse.
* ✅ Reduced Plastic Packaging: The move to a 90% plastic-free cardboard box is a significant improvement over the bulky plastic tubs that dominate the market. The box is easy to store and fully recyclable.
* ✅ Widely Available & Trusted Brand: Seventh Generation is one of the easiest eco-friendly options to find in major retail stores, making it a convenient and reliable choice.
* ✅ Great for Everyday Loads: It handled all of my daily dishwashing needs with ease, from dinner plates to coffee mugs, leaving everything clean and clear.
* ✅ Good Biobased Content: With 79% biobased ingredients, it’s a product you can feel good about using, as it relies heavily on plant-derived materials.

Cons: What Could Be Improved
* ❌ Contains a PVA Film: The pods are wrapped in a polyvinyl alcohol (PVA) film. While it’s designed to dissolve, there is an ongoing scientific debate about its complete biodegradability in all wastewater treatment systems.
* ❌ Not 100% Biobased: While 79% is very good, it does fall short of some competitors like Blueland that are closer to 100% bio-preferred.
* ❌ Can Struggle with Baked-On Messes: On a heavily soiled casserole dish, I found it sometimes left a few tough spots behind that required a bit of scrubbing. Workaround: For extremely baked-on food, a quick pre-soak or using the “heavy duty” cycle on my dishwasher ensures a perfect clean.

My Experience

Formula & Ingredients: As someone who strongly dislikes artificial chemical smells, I found the Seventh Generation Free & Clear Packs to be exceptional. Their “Free & Clear” promise absolutely holds up, making this my go-to recommendation for families with young children or anyone with skin or scent sensitivities. There’s no irritating fragrance left on the dishes you eat from.

Grease-Cutting Power: I was very pleased with its grease-fighting abilities. The enzyme-rich formula is effective at breaking down fats and oils without relying on harsh solvents. It consistently left plates and pans squeaky clean with no greasy film left behind.

Packaging Sustainability: While it’s not a fully plastic-free product due to the PVA film on the pods, the cardboard box packaging is a huge step in the right direction. It moves away from the single-use plastic tubs that are so common in this category. I appreciate the brand’s clear effort to reduce its plastic footprint.

Best Liquid Gel: Cascade Free & Clear Gel Review

For those who are loyal to liquid detergents, the Cascade Free & Clear Dishwasher Detergent Liquid Gel is the best eco-friendlier option I tested. It offers the familiar cleaning power and brand trust of Cascade but with a more thoughtful formula that is free of phosphates and chlorine bleach. It’s a great bridge for anyone wanting to switch to a greener clean without giving up the gel format they’re used to.

Specifications:
* Form: Liquid Gel
* Size: 75 oz
* Key Feature: Powers away 24-hour stuck-on food
* Packaging: Traditional Plastic Bottle
* Certifications: Formulated with 45% biobased ingredients

Pros: What I Liked
* ✅ Excellent on Stuck-On Food: This gel has impressive power and lives up to the Cascade reputation. It consistently dissolved food that had been sitting for a full day, which is a major convenience.
* ✅ Dosing Flexibility: This is the key advantage of a liquid. Unlike pre-measured pods, the gel format allowed me to adjust the amount of detergent based on the soil level and size of the load, which helps reduce waste.
* ✅ No Heavy Perfumes: The “Lemon” scent is very light and rinses away completely. It doesn’t leave an overpowering artificial fragrance on the dishes, just a hint of freshness.
* ✅ Free of Phosphates & Chlorine: It’s a significant and welcome step to see a major brand like Cascade offer a product that omits these harsh chemicals from its formula.
* ✅ Saves Water: The formula is strong enough that I could confidently skip the pre-rinse, even on moderately soiled dishes. This is a real benefit for conserving water and time.
* ✅ Dissolves Instantly: As a gel, it dissolves immediately and gets to work right at the start of the wash cycle, ensuring no clumps of powder are left behind.

Cons: What Could Be Improved
* ❌ Bulky Plastic Packaging: The biggest drawback is the packaging. The product comes in a standard, bulky plastic jug, which is a major negative from a zero-waste or plastic-reduction standpoint.
* ❌ Lower Biobased Content: At 45% biobased, its eco-credentials are less impressive than the other products on this list. It’s a step in the right direction, but not a leader in this regard.
* ❌ Vague Ingredient Disclosure: The claim of “thoughtfully selected ingredients” is a bit vague. I wish Cascade provided more transparency on the other 55% of the formula.
* ❌ Can Be Messy: As with any liquid gel, it can be easy to spill or use more than you need if you’re not careful when pouring.

My Experience

Liquid Gel Formula & Effectiveness: The gel consistency works very well and dissolves quickly even in shorter cycles. I found the Cascade Free & Clear Gel to be particularly effective on starchy residues like dried rice and potatoes, which can sometimes be tricky for pods to fully dissolve. Its ability to power away 24-hour stuck-on food is legitimate.

Ingredient Transparency: While I applaud Cascade for creating a “Free & Clear” option, I feel there’s room for improvement in transparency. It’s a good start, but brands like Blueland and Molly’s Suds set a higher standard for disclosing exactly what’s in their products.

Water-Saving Benefits: I put the “skip the pre-wash” claim to the test multiple times, and it held up. For a busy household, this is a fantastic real-world benefit that aligns with an overall eco-conscious mindset by saving a significant amount of water over time. If you must use a liquid, this is the one I’d choose.

Best for Families & Allergies: Molly’s Suds Dishwasher Pods Review

The Molly’s Suds Dishwasher Pods are my top recommendation for families, especially those with young children, or anyone managing chemical sensitivities and allergies. The brand’s story is compelling—it was developed by a pediatric nurse and mom who prioritized simple, safe, and effective ingredients. These pods gave me incredible peace of mind without ever sacrificing a sparkling clean.

Specifications:
* Form: Tablet (in a dissolvable pod)
* Count: 60 Pods
* Key Feature: Developed specifically for chemical sensitivities and allergies
* Packaging: Resealable Pouch
* Certifications: Leaping Bunny Certified Cruelty-Free

Pros: What I Liked
* ✅ Extremely Gentle Formula: Made with simple, naturally derived ingredients, these pods were my top choice for washing baby bottles, silicone plates, and anything my kids use daily.
* ✅ Truly Residue-Free Clean: Just as promised, my dishes came out sparkling clean with zero residue, streaks, or mineral build-up. This is a common failure point for many natural detergents, but Molly’s Suds excelled here.
* ✅ Effective in Hard Water: My home has moderately hard water, and these pods performed exceptionally well without needing a separate rinse aid. My glasses came out clear and spot-free.
* ✅ Cuts Grease Surprisingly Well: Despite the very gentle and simple formula, the active enzymes did a fantastic job dissolving grease and grime from dinner plates and cookware.
* ✅ “Mom Approved” Trust Signal: The origin story of the brand, created by a nurse, provides a powerful and authentic trust signal that I really value. It’s clear this product was made with safety as the number one priority.
* ✅ Cruelty-Free Certified: The Leaping Bunny certification is a must-have for me, ensuring no animal testing was involved in the product’s development.

Cons: What Could Be Improved
* ❌ Recommends Pre-Rinsing: The instructions suggest rinsing dishes with hot water before loading. This adds an extra step and uses more water, which runs counter to the water-saving benefits of other detergents.
* ❌ PVA Film Wrapper: Like some other pods, these use a dissolvable PVA film. This is a potential concern for zero-waste purists who prefer to avoid all forms of PVA.
* ❌ Resealable Pouch Packaging: While better than a hard plastic tub, the resealable pouch is still a form of flexible plastic that isn’t easily recycled in most municipal programs.

My Experience

Gentle & Residue-Free Cleaning: This is where Molly’s Suds truly shines. It provides a reliable, deep clean without leaving behind any of the chemical films or scents common with conventional detergents. I felt completely comfortable using this for every item in my kitchen, especially things used by my children.

Ingredients & Safety: The simple and understandable ingredient list is a breath of fresh air. It’s free from the harsh chemicals, fillers, and synthetic fragrances I actively try to avoid. The “Mom Approved” and pediatric nurse background isn’t just a marketing tactic; it feels genuinely baked into the product’s DNA.

Hard & Soft Water Performance: I was genuinely impressed by its effectiveness in my hard water. Many natural detergents can leave a white, chalky film on glassware when used in hard water, but these rinsed completely clean. The formula seems very well-balanced to prevent mineral deposits.

Best Concentrated Formula: If You Care Dishwasher Tablets Review

The If You Care Dishwasher Tablets are the smartest choice for the minimalist or the highly eco-conscious consumer focused on reducing their carbon footprint. Its tiny, super-concentrated tablet uses fewer raw materials and, because it’s so small and lightweight, requires significantly less energy to transport. This is a product designed from the ground up to minimize its environmental impact.

Specifications:
* Form: Tablet (in a dissolvable film)
* Count: 40 Tablets
* Key Feature: Super concentrated, small size reduces transport emissions
* Packaging: Recycled Cardboard Box
* Certifications: Non-toxic, free of phosphates and chlorine

Pros: What I Liked
* ✅ Powerful Concentrated Clean: Don’t let the small size fool you. This tiny tablet packs a serious punch and effectively cleaned a full, heavily soiled load during my testing.
* ✅ Reduced Environmental Footprint: I love the brand’s logic. A smaller, lighter product uses fewer raw materials and less energy for transport. This is a holistic approach to sustainability that I really appreciate.
* ✅ Biodegradable and Water-Soluble Film: The brand is transparent that the wrapper is PVA but specifies it is a water-soluble, biodegradable polymer, which I appreciate. The tablet itself is also fully biodegradable.
* ✅ Dissolves Very Quickly: The small tablet and its thin film dissolved rapidly at the start of the wash cycle, ensuring the cleaning agents got to work right away.
* ✅ Sustainable Packaging: The tablets come in a simple, unbleached, recycled cardboard box that is easily recyclable itself.
* ✅ Great for Travel/Small Spaces: The compact size of the box is fantastic for small kitchens, RVs, or anyone with limited storage space.

Cons: What Could Be Improved
* ❌ Smaller Count Per Box: The standard package comes with 40 tablets, which is fewer than many competitors. This means you may need to purchase it more frequently.
* ❌ Struggles on Extreme Messes: While it was great for 95% of my loads, it sometimes required a pre-soak or a second wash for extremely tough, caked-on foods like burnt cheese.
* ❌ Contains PVA Film: As with other pods, the presence of a PVA film is a drawback for those aiming for a completely zero-waste kitchen.

My Experience

Concentrated Formula & Efficiency: I was initially skeptical of the tablet’s tiny size, but it delivered a surprisingly powerful clean on a standard dinner load. For anyone actively trying to minimize their overall consumption footprint, the design of the If You Care tablets is fantastic. It’s a testament to efficient, concentrated formulas.

Biodegradable Ingredients & Film: The formula uses a thoughtful blend of mineral and plant-derived ingredients like coconut and rapeseed. It provides a great clean without relying on harsh chemicals. While I prefer no film at all, I appreciate the brand’s transparency about the PVA being a biodegradable polymer.

Environmental Impact: This product’s core mission is to reduce environmental impact, and it succeeds. From the recycled cardboard box to the concentrated tablet that reduces shipping weight and emissions, every element is designed to be a more responsible choice compared to bulky liquid detergents in plastic jugs.

Buyer’s Guide: How to Choose the Right Eco-Friendly Dishwasher Soap

The “best” soap ultimately depends on your household’s unique needs, such as your water hardness, allergy concerns, and personal sustainability goals. This guide will walk you through the key factors to consider so you can make a confident choice.

• Form Factor (Tablet vs. Pod vs. Powder vs. Gel): I find that tablets and pods offer the most convenience with no measuring and no mess. Powders offer excellent dosing flexibility and are often the most budget-friendly, but can be a bit messy to pour. Gels are familiar and effective, but almost always come in bulky plastic bottles. My advice: choose unwrapped tablets for zero waste, pods for convenience, and powders for budget-friendly flexibility.
• Packaging (Plastic-Free vs. Recycled): If your primary goal is achieving zero waste, look for products like Blueland that offer completely plastic-free tablets and refillable packaging systems. If your goal is simply to reduce plastic, options that come in recycled cardboard boxes, like Seventh Generation or If You Care, are a fantastic step in the right direction.
• Key Ingredients & Cleaning Agents: Always look for a transparent ingredient list. The most effective formulas use plant-derived enzymes (like amylase and protease) to break down protein and starch stains, along with mineral-based cleaners. Always avoid phosphates (which harm aquatic life) and chlorine bleach. If you have sensitivities, a “Free & Clear” option without any fragrances or dyes is essential.
• Hard Water Performance: If you have hard water (which is high in minerals like calcium and magnesium), you are much more prone to getting cloudy glasses and a white film on your dishes. I recommend choosing a formula specifically designed to work well in hard water, like Molly’s Suds, or one that contains citric acid to act as a natural water softener and prevent mineral deposits.
• Third-Party Certifications: These seals are your proof that a brand’s claims are legitimate. I prioritize products that carry the EPA Safer Choice logo, which verifies that every ingredient is safe for both human health and the environment. The Leaping Bunny seal is also crucial, as it certifies the product is 100% cruelty-free. Other great indicators of a truly sustainable brand include USDA Biobased, B Corp, and Climate Neutral certifications.
• PVA (Polyvinyl Alcohol) Film: This is the thin, dissolvable film that wraps most dishwasher pods. While it is marketed as biodegradable, some recent studies have raised questions about whether it breaks down completely in all U.S. wastewater treatment conditions. For the most eco-conscious choice, I strongly suggest “naked” tablets like Blueland’s or powders.

FAQs About Eco-Friendly Dishwasher Soap

Does eco-friendly dishwasher detergent actually work?

Yes, modern eco-friendly dishwasher detergents work exceptionally well. The best formulas, like the ones I reviewed, use powerful plant-based enzymes to break down tough, baked-on food and grease without harsh chemicals. After my testing, I can confidently say you no longer have to sacrifice cleaning power for safe ingredients.

What is the safest non-toxic dishwasher detergent?

The safest options are those with transparent ingredient lists that are free of phosphates, chlorine bleach, fragrances, and dyes. I recommend looking for products with the EPA Safer Choice certification, which independently verifies that every ingredient is safe for human health and the environment. Based on my review, Molly’s Suds and Blueland are excellent examples of safe, non-toxic options.

Are dishwasher pods bad for the environment?

It’s complicated, but they can be. The detergent inside the pod is generally safer for the environment than conventional formulas. However, most pods are wrapped in a Polyvinyl Alcohol (PVA) film. While designed to dissolve, there is a scientific debate about whether it fully biodegrades in all wastewater treatment facilities. For the lowest possible environmental impact, I recommend unwrapped “naked” tablets or powders.

Which eco-friendly dishwasher soap is best for hard water?

For hard water, you need a formula that can prevent mineral deposits (a white film) from forming on your dishes. In my testing, I found that Molly’s Suds Dishwasher Pods and Blueland Plastic-Free Tablets performed very well in hard water conditions, leaving glasses sparkling clean without needing a separate rinse aid.

Why are phosphates bad in dishwasher detergent?

Phosphates cause significant environmental damage when they enter waterways. They act as a powerful fertilizer for algae, leading to massive “algal blooms.” These blooms deplete the oxygen in the water, creating “dead zones” that kill fish and other aquatic life. All reputable eco-friendly brands are, and should be, completely phosphate-free.

Are dishwasher tablets better than liquid for the environment?

Generally, yes, tablets and powders are better for the environment than liquid detergents. They are more concentrated, which means they require less water to produce and are lighter to ship, significantly reducing their carbon footprint. They also typically come in more sustainable packaging, like cardboard boxes, compared to the bulky plastic jugs used for most liquids.

How does plastic-free dishwasher soap work?

Plastic-free dishwasher soap works just like any other detergent but comes in a “naked” tablet or powder form. Instead of being individually wrapped in a dissolvable plastic (PVA) film, you simply place the solid tablet directly into your dishwasher’s main dispenser cup. Blueland is the perfect example of this highly effective, zero-waste approach.

What makes a dishwasher soap “eco-friendly”?

An “eco-friendly” dishwasher soap is defined by several key factors. It must use biodegradable, plant- and mineral-based ingredients. It must be free of harsh, environmentally damaging chemicals like phosphates and chlorine. It should be cruelty-free (not tested on animals). And finally, it must come in minimal, plastic-free, or recycled/compostable packaging.

Can you get eco-friendly dishwasher soap at a refill station?

Yes, many zero-waste stores and local co-ops now offer dishwasher powder in bulk at refill stations. This is a fantastic way to eliminate all packaging waste. You simply bring your own clean, dry container to the store and fill it up, paying by weight.

Is Blueland dishwasher detergent effective?

Yes, in my extensive testing, Blueland was one of the most effective eco-friendly detergents I’ve ever used. Its unique 2x enzyme formula is specifically designed to tackle 48-hour baked-on food, and it performed exceptionally well on even my toughest messes, all while being 100% plastic-free.

My Final Verdict on the Best Eco-Friendly Dishwasher Soap

After weeks of testing five of the top eco-friendly dishwasher detergents, it is abundantly clear that you no longer have to compromise on performance to make a sustainable, healthy choice for your home. Each of these products offers a fantastic clean without the phosphates, chlorine, and harsh chemicals found in traditional detergents. While all five are excellent, one stood out from the pack.

My final recommendation for the best eco-friendly dishwasher soap is the Blueland 100% Plastic-Free Dishwasher Detergent Tablets. They deliver unmatched cleaning power that rivals and even surpasses conventional brands, especially on tough, dried-on food. Most importantly, they achieve this in a truly zero-waste, plastic-free format, satisfying both the performance-driven user and the sustainability-focused purist.

This is the perfect soap for you if:
* You want the most powerful clean possible from an eco-friendly product.
* Your goal is to achieve a 100% plastic-free dishwashing routine.
* You are willing to invest in a premium product for superior performance and sustainability.
* You value third-party certifications like EPA Safer Choice and B Corp.

This may not be ideal for you if:
* You are on a very strict budget.
* You strongly prefer a liquid or powder format.

If you are dealing with particularly sensitive skin or allergies in your family, my top alternative pick would be the Molly’s Suds Dishwasher Pods for its incredibly gentle and simple formula that still provides a sparkling, residue-free clean. No matter which you choose from this list, you can be confident you’re making a better choice for your home and the planet.
