How to Crochet a Space Planet with Rings Keychain Amigurumi: A Complete Step-by-Step Pattern

There’s something magical about holding a tiny planet in the palm of your hand. Amigurumi has always had a way of making the impossible feel touchable — turning dragons, mushrooms, and galaxies into soft, squeezable little creatures. This space planet with rings keychain amigurumi pattern is one of those projects that stops people mid-conversation. Clip it to your backpack, your keys, your zipper pull, or gift it to the astronomy lover in your life, and watch how quickly people ask, “Where did you get that?”

This pattern is beginner-friendly with just a few intermediate techniques. If you can crochet a magic ring and work in continuous rounds, you have everything you need to complete this project. The ring detail is what makes this pattern truly special, and once you see how it comes together, you’ll want to make one in every colorway imaginable — icy blue Saturn-inspired rings, warm terracotta rocky planets, or deep violet cosmic spheres dusted with glitter yarn.

Let’s dive into everything you need to know, from materials to finished product.

Materials You’ll Need

Before you sit down to crochet, gather your supplies. The beauty of a keychain amigurumi is that it uses very little yarn, so this is a wonderful stash-busting project. You can use leftover worsted weight scraps you already have on hand, or pick up small amounts of something new.

For this pattern you will need worsted weight yarn in two colors — one for the planet body and one for the ring (or you can use variegated yarn for a beautiful cosmic effect), a 3.5mm or 4.0mm crochet hook depending on your tension, a small amount of polyfill stuffing, a yarn needle for sewing and weaving in ends, stitch markers, scissors, and a keychain ring or lobster clasp with a short jump ring or chain. Optional but highly recommended is a small amount of black safety eyes in 6mm or 8mm, or you can embroider your own details if you prefer a flat face rather than a character look.

If you want to add some extra sparkle to your planet, consider mixing a strand of thin metallic thread with your main yarn as you work. The effect is subtle but absolutely stunning when it catches the light, and it makes the planet look like it belongs in the night sky.

Understanding Amigurumi Basics Before You Begin

Amigurumi is the Japanese art of crocheting or knitting small stuffed animals and figures. The techniques used are straightforward, but there are a few conventions that are important to follow if you want that smooth, even appearance.

Almost all amigurumi is worked in continuous rounds rather than joined rounds. This means you do not slip stitch to close each round and chain to begin the next — instead, you simply keep crocheting around and around in a continuous spiral. Use a stitch marker to mark the first stitch of each round so you always know where you are.

Amigurumi also typically uses a tighter tension than you would use for, say, a blanket or a hat. This prevents the stuffing from showing through the gaps in your stitches. If your stitches look loose, go down a hook size.

All stitches in this pattern are US crochet terms. A single crochet is sc, an increase is inc (two single crochets worked into the same stitch), and a decrease is dec (an invisible decrease worked through the front loops of two consecutive stitches).

Crochet Planet Body Pattern

The planet body is a classic amigurumi sphere. You can make it slightly larger or smaller depending on your hook size and yarn weight, but these instructions will produce a planet that is roughly 2 to 2.5 inches in diameter — a perfect, palm-sized little world.

Start with a magic ring. If you’re unfamiliar with the magic ring technique, it creates an adjustable loop that allows you to pull the center of your work completely closed so no hole remains. It is worth learning if you haven’t already, as it gives your amigurumi a professional, polished starting point.

Round 1: Work 6 single crochets into the magic ring. Pull the tail to close the ring. You will have 6 stitches.

Round 2: Increase in each stitch around. You will have 12 stitches.

Round 3: [Sc 1, inc] repeat 6 times around. You will have 18 stitches.

Round 4: [Sc 2, inc] repeat 6 times around. You will have 24 stitches.

Round 5: [Sc 3, inc] repeat 6 times around. You will have 30 stitches.

Round 6: [Sc 4, inc] repeat 6 times around. You will have 36 stitches.

Rounds 7 through 10: Single crochet in each stitch around. You will have 36 stitches in each of these rounds.

If you are placing safety eyes, this is the moment to do it. Insert your eyes between rounds 8 and 9, spaced approximately 6 to 8 stitches apart. Once the safety eyes are clicked in from the back, they cannot be removed, so take a moment to consider the placement before you commit. Some people like to give their planet a cute face, while others prefer a clean, decoration-only look — both are completely valid and beautiful.

Round 11: [Sc 4, dec] repeat 6 times around. You will have 30 stitches.

Round 12: [Sc 3, dec] repeat 6 times around. You will have 24 stitches.

Round 13: [Sc 2, dec] repeat 6 times around. You will have 18 stitches.

At this point, begin stuffing your planet firmly with polyfill. You want it to feel full and round without being so tightly packed that it distorts the shape. Add stuffing a little at a time and check the shape from the outside as you go. Continue to add stuffing as you work the final closing rounds.

Round 14: [Sc 1, dec] repeat 6 times around. You will have 12 stitches.

Round 15: Dec 6 times around. You will have 6 stitches.

Cut your yarn, leaving a 6-inch tail. Thread the tail onto your yarn needle and draw it through the front loop of each remaining stitch, pulling tight to close the opening completely. Weave in the end securely on the inside of the planet. Your sphere is complete.

Crochet Planet Ring Pattern

The ring is what takes this from a simple amigurumi ball to a recognizable space planet, and it is far less complicated to make than it might look. The ring is worked as a flat oval or circle and then attached around the equator of the planet.

You have a couple of options here. The simplest approach is to crochet a foundation chain and then work in rows to create a flat, elongated oval that you’ll shape around the planet. The second and slightly more advanced option is to work the ring in the round as a flat circle with a hole in the center, through which the planet sits. Both produce a lovely result, and the instructions below cover the flat oval method, which is easier for beginners.

Using your ring color yarn and a 3.5mm or 4.0mm hook, chain 30. Slip stitch into the first chain to form a loop, being careful not to twist your chain. You now have a ring-shaped foundation.

Round 1: Chain 1, single crochet in each chain stitch around. Slip stitch to join. You will have 30 stitches.

Round 2: Chain 1, [sc 2, inc] repeat around, adjusting the last repeat as needed to maintain the circle shape. Slip stitch to join.

Round 3: Chain 1, single crochet in each stitch around. Slip stitch to join.

Fasten off and leave a long tail for attaching.

Alternatively, for a thicker, more dimensional ring, you can work an additional round of single crochets before fastening off. The ring should be large enough to sit comfortably around the planet body without pulling or distorting either piece.

If you want an even simpler ring, you can also create a foundation ring by chaining 30, joining, and then immediately sewing the circle onto the planet without adding additional rounds. The unstuffed, single-layer ring has a lovely delicate quality that looks great in metallic or glittery yarn.

Attaching the Ring to the Planet

Lay your planet flat on your work surface with what you consider the “north pole” pointing up. The equator runs around the middle of the sphere. Hold your ring up and visualize it wrapping around this equator at a slight angle — Saturn’s rings are actually tilted, and that slight diagonal placement makes your planet look much more realistic and dynamic.

Thread your long yarn tail onto your yarn needle. Working in small, even stitches, sew the ring to the planet along the bottom edge of the ring first, stitching all the way around the back half of the planet. Then bring the needle around and sew the top edge of the ring to the front of the planet in the same way.

The goal is for the ring to appear to pass behind the planet on one side and in front of the planet on the other side, giving the illusion that it actually encircles the planet. You can reinforce this optical illusion by using a few stitches in a matching yarn color to tack the front portion of the ring down against the planet surface. When you’re done, your planet should look like it has a ring floating around its middle.

Adding the Keychain Hardware

Now for the practical part — turning your little planet into a functional keychain. Cut a short length of chain (about 1 to 1.5 inches is usually enough) or use a pre-made lobster clasp and short chain set, which you can find at any craft store or online.

Using your yarn needle and a length of the planet’s main color yarn, stitch through the top of the planet (the north pole) several times, threading the yarn through the first link of the chain each time, to secure it firmly. You want this connection to be very secure since the keychain will take regular pulling and tugging. After 8 to 10 passes through the chain link and the top of the planet, knot your yarn securely on the inside and weave in the end.

Attach your keychain ring or lobster clasp to the other end of the chain. Your planet keychain is now complete.

Color Inspiration for Your Space Planet Keychain

One of the most fun parts of this project is choosing your colorway. Here are some combinations that work beautifully and are hugely popular if you’re planning to sell these at craft fairs or on Etsy.

A pale blue planet with white rings evokes the icy elegance of Neptune or Uranus. A golden yellow planet with dusty orange rings looks like a stormy gas giant with atmospheric bands. A terracotta and rust planet with deep brown rings suggests a rocky, desert world straight out of science fiction. A deep navy or black planet with shimmering silver or white rings looks almost exactly like a stylized Saturn and is arguably the most recognizable design. A pastel rainbow variegated planet with a coordinating solid ring is endlessly charming and appeals to everyone from children to adults.

You can also embroider swirls, dots, or stripes onto the planet surface after the amigurumi is complete to add texture and visual interest. A simple spiral of surface slip stitches or a few long embroidery stitches in a contrasting color can suggest atmospheric bands without adding any real complexity to the construction.

Tips for Making Multiple Planets to Sell

If you’ve fallen in love with this pattern and want to sell your planets at markets or in an online shop, a few efficiency tips will make your production process much smoother.

Work all your planet bodies in one sitting before switching to rings. Assembly-line crocheting is significantly faster than completing each piece from start to finish before starting the next one. Keep a stash of pre-cut lengths of yarn for sewing so you’re not stopping to measure yarn every time you attach a ring. Invest in a small bag of keychain hardware in bulk — lobster clasps and jump rings are inexpensive when bought in larger quantities.

Price your work fairly. A keychain like this requires real skill and time, and yarn, hardware, and packaging all cost money. Research comparable amigurumi keychains in your market and price accordingly. Many makers underprice their work significantly, and the handmade market benefits when makers price sustainably.

Caring for Your Amigurumi Planet Keychain

Acrylic yarn, which is what most amigurumi is made with, is remarkably durable and can be spot-cleaned with a damp cloth and mild soap. If the keychain gets dirty, gentle hand washing and air drying will restore it beautifully. Avoid machine washing, as this can distort the shape and loosen the stuffing.

The keychain hardware is not waterproof, so if you expect the keychain to get wet regularly, look for stainless steel or coated hardware that is rated for outdoor or water exposure.

Final Thoughts on Your Space Planet Amigurumi Keychain

This little planet is one of those patterns that earns its place in your permanent rotation. It’s quick enough to finish in a single evening, satisfying enough to make you feel proud every time you see it clipped to your bag, and charming enough to make a wonderful handmade gift for literally anyone. Space is universally fascinating, and a handmade planet keychain carries that wonder with it wherever it goes.

Once you’ve made one, try scaling up to a larger planet without a keychain attachment as a desk decoration, or make a whole solar system’s worth of planets in graduating sizes to hang as a mobile. The pattern is endlessly adaptable, and once you understand the sphere and ring construction, the galaxy really is the limit.

Happy crocheting, and may your planets always be perfectly round and your rings always sit just right.
