ShareA satellite is any object that orbits another object (which is known as its primary).
Satellites can be manmade or may be naturally occurring such as moons, comets, asteroids, planets, stars, and even galaxies.
All masses that are part of our solar system, including the Earth and Sun, are satellites of either a planet, the Sun, or the galactic center of the Milky Way.
