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.
No, Mercury is not one of the biggest planets in the solar system. It is the smallest planet in our solar system, with a diameter of about 4,880 kilometers.
Earth is one of the planets in our solar system.
Mercury is a planet in our solar system, not a solar system itself. Our solar system has eight planets, and Mercury is the closest planet to the sun.
No one knows how many planets are in our nearest solar system, Alpha Centauri.
There are 8 planets in the solar system, 6 have at least one moon. Mercury and Venus have no known moons.
Only one planet is out of the solar system that is Pluto .
All of the planets in the Solar System except for Mercury and Venus have at least one moon.
more then one
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.
Well, there are planets outside of the solar system, and there is one that is livable, but I don't know what it is called.
