What is the definition of satellite?

Answer 1

In terms of space, a satellite is a body that orbits around another. This can be either a natural satellite, like the moon orbiting the Earth, or an artificial one like the Mariner 10 satellite or the communications satellites that daily provide us with access to information worldwide.

A natural satellite or moon is a celestial body that orbits a planet or smaller body, which is called the primary. Technically, the term natural satellitecould refer to a planet orbiting a star, or a dwarf galaxy orbiting a major galaxy, but it is normally synonymous with moon and used to identify non-artificial satellites of planets, dwarf planets, and minor planets. (There are no known natural satellites of moons.)

A satellite is essentially something that orbits a planet, it can be man made (eg. GPS satellites) or celestial bodies (eg. the earths moon).

A satellite is an artificial body put in to orbit around the earth, sun, moon or planet for communication purposes or to collect information.
A satalite is an object that orbits another object. For example, the moon is a satalite because it orbits the Earth. The Earth is also a satalite because it orbits the sun. Any rock that is orbiting the Earth right now is also a satalite etc, etc.

Answer 2

A satellite is a natural or artificial body that orbits around a larger body, typically a planet. Artificial satellites are human-made objects launched into space to perform various functions, such as communication, navigation, and scientific research.
