It is always difficult to appreciate the sizes of the planets and the relative distance between all the planets of our solar system. While this scale model of the solar system is not exact or a true scale, it will give kids some relative sizes of the planets while giving them a bigger appreciation for the vast nature of space.

How to Make A Solar System Model for Kids

Step 1

Step 1 - Solar System Project - Sun and the planets are cut from the solar system coloring pages to make solar system for kids
Turn these planets and the sun into a solar system mobile for kids.

Print two copies of the solar system coloring pages on white card stock.

Step 2

Using markers, crayons or colored pencils, color the sun and planets.

Step 3

Step 3 - Solar System Project - Glue is applies on the back side of the planet and the thread is put on the glue to cover it with another piece to form a hanging planet mobile
Glue two pieces of each planet together with a piece of thread sandwiched between to make the solar system craft.

Cut around each planet and the sun, leaving a small white border on the outside. For one half of the sun leave about half an inch of white space at the bottom, as pictured above.

Step 4

Step 4 - Solar System Project - All the planets and sun are glued and ready to be hanged on to the cardstock beam to form a planet mobile.
Next it is time to add what will hang the planets.
  1. Apply glue at the back of one copy of each planet.
  2. Place one end of the thread covering the length of the planet and then place the other piece above to secure it.
  3. Repeat the same for all the planets to make the solar system mobile.

For the sun to make it look like the real sun, apply glue to the bottom white space and glue the other half by overlapping. Use a small piece of white cardstock to secure the thread at the back of the sun.

Solar System Model Tip: If you want to make them a little extra sturdy, try laminating them!

Make a Hanging Frame for Your Planet Mobile

At this point, you could hang your planets and sun from the ceiling of your bedroom or classroom or use in another way. If you want to create a mobile for your planets like we did, we need to make a frame!

Step 1

Step 1 - Create a frame for solar system project - A rectangle piece of cardstock with four holes and a 1/2 inch cut in the middle to form a hanging frame for hanging the solar system planets
Make two pieces of cardstock to connect in the middle for a hanging frame to hang the planets.

Cut two pieces of cardstock measuring 7.5 inches by 1 inch.

Step 2

Make a 1/2 inch cut in the center of each piece, at the 3.75-inch mark. Punch 4 holes using a hole punch with an equal distance in both the piece of cardstock.

Step 3

Step 3 - Create a hanging frame for solar system project - Two pieces of cardstock connected in the center to hang the planets through the holes punched
Use this “X” shaped hanging frame with holes to hang the planets.

Connect the two pieces of cardstock in the middle with the 1/2 inch cut facing up for one and 1/2 inch cut facing down for the other. This will form the frame for your solar system project model.

Step 4

Step 4 - create a hanging frame for hanging Solar system project using planets coloring pages
Hang planets around the sun using thread for a simple solar system project.

Attach the sun in the center by wrapping the thread around in the center point of the “X” shaped hanging frame and tying a knot. You can also use a piece of tape for extra security. 

Step 5

Step 5 - With sun in the center and other planets are hanged from the cardstock hanging frame as a solar system hanging mobile
This DIY Solar System mobile project is a fun space craft for kids.
  1. Loop the thread through each hole to attach the planets.
  2. Start by threading the inner planets — Mercury, Venus, Earth, and Mars — in the holes near the sun.
  3. Then add the outer planets — Jupiter, Saturn, Neptune, and Uranus — in the outer holes of the hanging frame.

Kids can appreciate the different sizes of the planets while placing them in the correct order. Turn off the lights and look up into the night sky…giggle.

How to Hang the Solar System Mobile

To hang the frame, connect two pieces of ribbon that are the same length across the “X” frame. Tie a knot in the outer holes of the frame to secure. Take another piece of the ribbon or string and tie a knot at the end of the string in the center to hang the solar system project.
