Planets are honestly one of the most exciting subjects you can bring to a craft table. Just saying the names out loud feels exciting to kids. Mercury, Venus, Mars, Jupiter, Saturn. Each one has its own colour, its own personality, and its own incredible set of facts attached to it.
And the best part about planet crafts is how naturally they teach real science.
Kids who make their own planets remember the order, the colours, and the key facts in a way that reading alone never achieves. And if you have been making cheerful ladybug crafts lately, go check out 21 Ladybug Craft Ideas That Are Bright, Cute, and Fun because mixing garden insects with outer space exploration makes for the most wonderfully varied craft week imaginable.
So let us blast off into these 25 planet craft ideas that make learning about space genuinely exciting.
1. Balloon Planet Mobile
Blow up balloons in different sizes to represent each planet. Cover them in papier mache and let dry completely. Pop the balloons and paint each sphere with the correct planet colours and patterns. Hang them in order from a dowel.
A balloon planet mobile is one of the most impressive projects on this entire list.
The different balloon sizes naturally create a sense of relative scale between the planets. Painting each one accurately requires real research and attention to detail. Hanging them in the correct order from the sun reinforces the sequence in a way that sticks for years. This project takes several sessions but the result is genuinely spectacular.

2. Salt Dough Planets
Mix salt dough from flour, salt, and water. Roll into balls of different sizes for each planet. Bake until hard. Paint with the correct colours and patterns once cooled. Add a coat of varnish for shine.
Salt dough planets have a lovely solid weight that makes them feel like real objects worth studying.
Kids enjoy the whole process from mixing the dough to rolling perfect spheres to painting the final details.
The texture of salt dough takes paint beautifully and the varnish gives Jupiter and Saturn that gorgeous glossy gas giant look. Line them up on a shelf in order for a permanent solar system display.
3. Paper Mache Saturn
Cover a balloon in papier mache for the planet body. Cut a large ring from card and cover it separately in papier mache. Once both are dry and painted, slot the ring around the sphere to create Saturn’s iconic rings.
Saturn is everyone’s favourite planet to make because of those rings.
Kids get genuinely excited when the ring slides onto the sphere and suddenly looks exactly like the real thing. Paint the rings in pale golden tones with subtle darker bands for a really realistic effect. This project teaches kids that Saturn’s rings are made of ice and rock without them even realising they are absorbing that fact.

4. Planet Painting With Sponges
Cut circles of different sizes from sponge. Dip each one in the correct planet colour and stamp it onto black or dark blue paper. Add details with a fine brush once dry. Arrange all eight planets in order across the page.
Sponge painted planets are quick, satisfying, and produce a really beautiful result on a dark background.
The dark paper makes every planet colour pop dramatically, just like the real planets against the blackness of space. Kids enjoy the stamping process and the immediate visual reward of seeing a planet appear with one press.
Add white dot stars across the background once the planets are dry for a complete and stunning night sky scene.
5. Marble Run Solar System
Set up a marble run track and place painted polystyrene balls at different points to represent planets. Send a marble through to represent a spacecraft travelling through the solar system.
This activity combines building, physics, and space learning into one completely absorbing project.
Kids work out how to position their planets along the track and test different paths for the marble. The engineering thinking involved is genuinely sophisticated. Talk about distances and travel time between real planets while building. The combination of physical building and space facts creates a really memorable learning experience.

6. Glow in the Dark Planets
Paint polystyrene balls with the correct planet colours. Add a layer of glow in the dark paint over the top in a thin coat. Hang them from the ceiling. Turn off the lights at bedtime and watch the solar system glow.
Glow in the dark planets turn a bedroom ceiling into a genuine night sky every single evening.
Kids who make these often say goodnight to their planets before going to sleep which is genuinely lovely. The glowing effect creates a sense of wonder that lasts long after the craft session is finished.
This project also sparks brilliant bedtime conversations about what is really happening up there while everyone sleeps.
7. Planet Bottle Cap Magnets
Paint the inside of bottle caps with planet colours and patterns. Glue a small magnet to the back of each one once dry. Use them to hold notes and pictures on the fridge.
Planet bottle cap magnets are wonderfully quick and genuinely useful once finished.
Kids love that their tiny planets serve a real purpose in the home every single day. Make a full set of eight and arrange them on the fridge in the correct order from the sun. Every time someone goes to the fridge they see the solar system in the right sequence which quietly reinforces the learning over and over again.

8. Planet String Art
Hammer small nails around the outline of a circle drawn on a wooden board. Wrap coloured string around the nails in patterns to create a textured planet. Use different colours for different planets.
Planet string art looks genuinely impressive and the process is really satisfying for older kids.
The careful winding of string around nails requires patience and produces a beautifully textured result that catches the light in interesting ways. Older kids who enjoy detailed precise work find this project particularly absorbing.
The finished string art planets look like proper pieces of art that deserve a real frame.
9. Planet Size Comparison Chart
Use round objects of different sizes to represent each planet according to its real relative size. A basketball for Jupiter, a golf ball for Earth, a peppercorn for Mercury. Arrange them in a line and label each one.
This activity makes the abstract concept of planetary scale suddenly and completely real.
Kids are genuinely shocked by how much bigger Jupiter is than Earth and how tiny Mercury looks beside it. That visceral understanding of scale only comes from holding the objects and seeing the comparison with their own eyes. Take a photo of the finished comparison line for a record that captures this striking moment of discovery.
For more wonderful hands on science activities that create these kinds of memorable discovery moments, go take a look at 21 Bear Craft Ideas Kids Will Absolutely Love Making because those projects show how physical making leads to deeper understanding than reading ever could.
10. Cardboard Tube Planet Stands
Cut cardboard tubes into different heights. Paint each one to represent the orbit path of a planet. Place a small painted polystyrene ball on top of each tube to represent the planet at that distance from the sun.
This project visually represents the increasing distances between planets in a really clever way.
Taller tubes for planets further from the sun immediately show kids that Neptune is much further away than Mercury. Arrange the tubes in a row from shortest to tallest with a sun symbol at one end.
This simple visual makes the concept of orbital distance click in a way that numbers on a page rarely achieve.
11. Planet Mask Craft
Cut a large circle from card with eye holes cut out. Paint the circle to look like a specific planet. Attach elastic or a stick handle. Wear the mask and become that planet for the day.
Planet masks are brilliant for imaginative play and dress up days.
Kids who wear a Mars mask all day start to think and talk about being Mars. What is it like being red. What is it like having two tiny moons. This kind of imaginative embodiment creates a really personal connection to the planet that pure facts never quite achieve. Make a full set for a whole class solar system day.

12. Watercolour Galaxy Planets
Wet watercolour paper completely. Drop deep blues, purples, and pinks across the surface and let them bleed freely. Once dry, cut circles from the painted paper to create beautifully marbled planet shapes. Mount on black card.
Watercolour galaxy planets look absolutely breathtaking and the marbled effect makes every single one completely unique.
The wet on wet technique creates organic blending that looks genuinely like swirling gas clouds on a real gas giant planet.
Cutting circles from the dried painted paper means kids get to choose which section of the marbling becomes their planet, adding a lovely element of curation to the process. Mounted on black card these look like real space photography.
13. Pipe Cleaner Orbit Models
Bend pipe cleaners into circles of different sizes to represent each planet’s orbit. Thread a small bead onto each pipe cleaner to represent the planet. Arrange the circles concentrically around a central sun.
Pipe cleaner orbit models create a simple working representation of the solar system structure.
Kids can spin the bead planets around their pipe cleaner orbits which adds a wonderful interactive element. The concentric circle arrangement clearly shows how each planet has its own path around the sun. This model is quick to make but genuinely effective at teaching the basic structure of our solar system.

14. Planet Puzzle Pieces
Cut large circles from card to represent each planet. Cut each circle into several jigsaw style pieces. Mix up all the pieces and challenge kids to reassemble each planet correctly.
Planet puzzles combine fine motor skills with planet recognition in a really fun way.
Kids who put the puzzles together repeatedly start to recognise each planet by its colours and patterns even from individual pieces. Make the puzzles progressively harder by cutting more pieces for older kids.
This activity works brilliantly as a calm focused session after a more energetic planet making activity.
15. Recycled Material Planets
Collect recycled materials. Bottle caps for Mercury, a tennis ball for Earth, a basketball for Jupiter. Paint and decorate each item to represent its planet using the natural size of the recycled object as a guide.
Using recycled materials of genuinely different sizes teaches relative scale in the most natural way possible.
Kids search through recycled materials looking for objects whose size feels right for each planet which is itself a really valuable thinking exercise. The finished collection looks wonderfully varied and interesting because every object started life as something completely different. This project is also brilliant for environmental awareness conversations.

16. Planet Fact File Booklets
Make a small booklet for each planet by folding and stapling a few pages of paper together. On the cover, draw or paint the planet. Inside, write or draw facts about temperature, moons, size, and anything else discovered through research.
Planet fact file booklets combine art, research, and literacy in one really satisfying project.
Kids who create their own fact files engage with research in a much more purposeful way than simply being told facts. The drawing on the cover gives ownership and pride to each booklet. Keep all eight booklets together in a special box as a growing reference library that kids return to again and again.
17. Planet Sensory Bottles
Fill clear bottles with tinted water in the colour of a specific planet. Add glitter, small beads, and tiny star sequins. Seal tightly. Make one bottle for each planet using the correct colours.
Planet sensory bottles are mesmerising and the colour accuracy makes them genuinely educational as well as beautiful.
A deep orange and white swirled bottle for Jupiter. A pale blue bottle for Neptune. A reddish orange bottle for Mars. Kids learn the colours of each planet through repeated playful interaction with these calming bottles.
Line up all eight bottles in order for a stunning and genuinely useful sensory display.

18. Foam Ball Planet Set
Cover polystyrene foam balls of different sizes with paint in the correct planet colours. Add surface details like the great red spot on Jupiter or the polar ice caps on Mars using smaller pieces of painted foam or paper.
A foam ball planet set is one of the most classic and effective space crafts available.
The lightweight foam balls are easy for kids to handle and paint without the mess of papier mache. Adding surface details requires research into what makes each planet visually distinctive.
This project produces a genuinely impressive permanent solar system model that can be displayed on strings or stands for years.
19. Planet Mask Theatre
After making planet masks, write a short script where each planet introduces itself and shares a few facts. Perform the planet play for family members with each child playing their assigned planet.
Planet mask theatre combines performance, research, and public speaking with space learning in a really powerful way.
Kids who have to explain their planet to an audience research more thoroughly and remember more deeply than kids who just read facts silently. The performance element adds genuine excitement and a sense of occasion to the whole project. This works brilliantly as the culmination of a longer space themed learning unit.

20. Planet Mobile With Facts
Make a simple mobile using painted polystyrene or paper planets. Attach a small fact card to a ribbon hanging beneath each planet. Hang the mobile somewhere it will be seen often.
Adding fact cards to a planet mobile turns a beautiful decoration into an ongoing learning tool.
Every time someone walks past and reads a fact card they reinforce that piece of knowledge a little more.
Kids enjoy choosing which fact to include for each planet, which means they have to decide what they find most interesting or important. That decision making process is itself a valuable part of the learning.
21. Star and Planet Constellation Map
Create a large dark background using black card or fabric. Add the eight planets in their correct positions along an orbital line. Add constellation patterns using white paint dots or star stickers around the edges.
A constellation and planet map combines two space topics into one impressive piece of art.
Kids who make this map develop a sense of how planets and stars relate to each other in the night sky. The large scale of the project allows for real detail and the finished map looks genuinely impressive displayed on a wall.
This project works brilliantly as the centrepiece of a space themed bedroom or classroom display.

22. Planet Yoga Poses
Create a yoga pose to represent each planet. A tight curled ball for Mercury. A wide stretched star shape for Jupiter. A spinning pose for Saturn with arms out like rings. Move through all eight poses in order.
Planet yoga combines physical movement with space learning in a beautifully calming way.
Kids remember the planets through the physical poses associated with each one in a way that pure memorisation never achieves.
This activity works wonderfully as a calm transition activity after a more energetic planet making session. The combination of movement, breath, and space facts creates a really lovely mind and body learning experience.
23. Planet Pom Pom Mobile
Make pom poms in the correct colours for each planet using wool wrapped around cardboard circles. Attach each pom pom to a length of thread and hang from a dowel in the correct order.
Pom pom planets are wonderfully soft and tactile compared to painted or papier mache versions.
The fluffy texture gives the mobile a really gentle and cosy quality that suits a bedroom space beautifully.
Making eight pom poms in the correct colours requires careful wool selection which is itself a valuable colour matching exercise. The finished mobile sways gently and looks genuinely beautiful hanging in a window.
Go take a look at 33 Hedgehog Craft Ideas That Are Adorably Creative for more wonderful pom pom and soft texture craft ideas that bring warmth and softness to any themed display.
24. Asteroid Belt Craft
Roll many small balls of grey and brown clay or paper mache to represent asteroids. Arrange them in a ring between models of Mars and Jupiter on a solar system display.
The asteroid belt is often forgotten in solar system crafts and adding it makes the model genuinely more accurate and interesting.
Kids enjoy the repetitive process of rolling lots of small asteroid shapes and the conversation about where the asteroid belt sits and what it is made of happens naturally during this repetitive making.
This small addition makes a huge difference to how complete and impressive the finished solar system display looks.
25. Complete Solar System Display
Bring together planets, the asteroid belt, the sun, and orbital paths into one complete display. Use a large round table or a section of floor. Arrange everything in correct order and proportion as much as possible.
A complete solar system display is the ultimate culmination of a space themed craft unit.
Bringing together everything made across multiple sessions into one final display creates a genuine sense of achievement and completion.
Kids who walk around their own solar system display, pointing out facts about each planet they made themselves, demonstrate learning that has truly stuck. Photograph the finished display for a lasting record of an incredible project.
