Solar System Exploration
A solar system is a group of heavenly bodies consisting of a star and the planets and other objects orbiting around it. We are most familiar with our own solar system, which includes Earth, seven other major planets, and the sun. Our solar system also includes many smaller objects that revolve around the sun, such as dwarf planets, meteoroids, and comets; and a thin cloud of gas and dust known as the interplanetary medium.
