A satellite is any object that orbits another object (which is known as its primary). All masses that are part of the solar system, including the Earth, are satellites either of the Sun, or satellites of those objects, such as the Moon.
Definition of a Satellite
It is not always a simple matter to decide which is the "satellite" in a pair of bodies. Because all objects with mass are affected by gravity, the motion of the primary object is also affected by the satellite. If two objects are sufficiently similar in mass, they are generally referred to as a binary system rather than a primary object and satellite; an extreme example is the 'double asteroid' 90 Antiope. The general criterion for an object to be a satellite is that the center of mass of the two objects is inside the primary object.
In popular usage, the term satellite normally refers to an artificial satellite, which would be a man-made object that orbits the Earth (or another body). However, scientists may also use the term to refer to natural satellites, or moons. In general word usage, "natural satellite" is the term used to refer to moons.

@poemaboutrobots Wow! You got 1997 for Christmas, too? I'm going to go listen to Recovering the Satellites and read my new RL Stine books.

@michellemalkin Wish it was worth it, Reagan style military spending, beans and bullets and more gear, satellites that defend themselves?!

@nahillie Hi there! I have been out of reach of satellites for many a day, you know what it's like in the South! Good to hear from you!
