To make a model of the solar system, hang circles representing the planets from a larger circle of cardboard. By varying the length of the string and hanging the cardboard planets in orbital circles, the model is even more precise.Know More
Only a few supplies are necessary to make a model of the solar system. Gather heavy pieces of cardboard, string or twine, a compass to make circles, scissors and crayons or markers.
Step 1: Cut circles out of the cardboard
Use a large circle from which to hang the smaller cardboard planets. A circular piece from a frozen pizza works well. Cut eight smaller circles from the cardboard to represent the planets. Cut a larger circle to represent the sun. Decorate them as desired with crayons or markers.
Step 2: Draw the orbital circles
Using the compass, draw orbital circles on the large circular piece of cardboard. There are four orbits close to the middle, where the sun hangs. Then there is a space that represents the asteroid belt, followed by the remaining four. Punch a hole in the middle, then one hole on each of the orbital circles.
Step 3: Hang the planets
Tie a knot in one end of a piece of string and thread through each hole from step two. Use a piece of tape to attach the sun (in the middle) and planets from the end of each of the strings.Learn more about Planets
Outer planets of the solar system are made predominantly of gases. They tend to have many more moons than the inner planets, and outer planets take a shorter period of time to rotate around their axes.Full Answer >
One of the easiest ways to make a model of a solar system is to cut circles from cardboard to represent the planets and hang them in orbits from a larger circle. Use nine circles to represent the eight planets and the sun.Full Answer >
From largest to smallest, based on total circumference, the planets that make up this solar system are Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars and Mercury. Any publication that lists Pluto as a planet is out of date. Astronomers now consider Pluto a dwarf planet.Full Answer >
Mercury and Venus are the two planets in the solar system without any moons. This is likely due to the close proximity of both planets to the sun.Full Answer >
