Solar System Mobile

7-10 year olds | two hours

Learn more about the universe around us with this craft. Kids will love learning about the colours and sizes of the planets, as well as where they ‘live’ in the solar system.

What You'll Need

  • cardboard (old pizza boxes or mailing boxes work great)
  • scissors
  • string
  • pair of compasses
  • tape
  • paint or markers
  • hole punch
  • pencil


  1. Draw a large cardboard circle on the back of a pizza box or other large piece of cardboard. This will be the top of your mobile.
  2. Cut out the circle.
  3. Find the centre of this circle by drawing two lines, from top to bottom and left to right.
  4. Use a pair of compasses to draw four circles a few centimetres outside of the centre, always leaving space between the rings.
  5. Now leave a large space of about 4-5 centimetres and then start making circles with the compass again, making four more. There should be eight rings total.
  6. Using a hole punch or scissors, poke a hole in the centre of the circle. Also, poke a hole on a different place on each ring, making sure that the planets won’t cluster to one side of their orbits.  
  7. Now, cut out eight circles of varying sizes from cardboard. To find relative sizes of the planets, check out  this wikipedia page about our solar system.
  8. Colour each planet accordingly. Remember to draw rings on Saturn. Don't forget to tell them: "When I was your age, pluto was a planet!"
  9. Tape a piece of string to the top of each of the planets and pull the string through the corresponding holes in their orbits. Tape to secure.
  10. Punch an additional four holes on the edges of the mobile top. Thread string through and hang.
