Objects that revolves around another object in space?

Answer 1

Many different objects in space revolve around many other things. Usually, it is acceptable to use the term 'satellite' when describing a moon's orbit around a planet, or even a planet's orbit around a star.

Answer 2

These are known as satellites. Satellites can be natural, like moons orbiting planets, or artificial, such as man-made satellites orbiting Earth or other celestial objects. The gravitational pull of the larger object keeps the satellite in orbit.
