What is a space probe?

A space probe is an unmanned craft which is sent into space to do research. When we want to get close up pictures and information about the planets, moons, comets, and asteroids in our Solar System, we send out space probes. Space probes can carry special cameras and instruments far out into the solar system. Some space probes study many planets and moons while flying past them. Others go into orbit around a planet or moon to study it more closely.
