A model of a solar system, complete with planets, is a great project for children. The two main types of solar system models are box models and hanging models. A large ball, such as a foam ball or toy ball, can be used to represent the sun. The planets can be represented using Styrofoam balls.
One way to categorize the solar system's planets?
No. The sun and the planets form the Solar System, which is just one infinitesimally small part of the Milky Way.
Earth is one of the planets in our solar system.
Six planets have more than one moon in our solar system.
Only one planet is out of the solar system that is Pluto .
No one knows how many planets are in our nearest solar system, Alpha Centauri.
There are 18 known planets in the solar system that includes Mercury.
There are 8 planets in the solar system, 6 have at least one moon. Mercury and Venus have no known moons.
One of the discoveries that led to the modern view of the Solar System was that the "orbits" of the planets were ellipses.
All of the planets in the Solar System except for Mercury and Venus have at least one moon.
No, it is one of the smallest.
There are a great number of web sites that discuss the solar system. One of my favorites is "The Nine Planets" at http://nineplanets.org.
