Explanation
A satellite is something small or less powerful that orbits around something bigger. It often describes a body in space, such as an artificial satellite that orbits the Earth and beams down signals that power devices like cell phones. The word satellite was first used to describe a follower of someone in a superior position. The word's meaning later broadened to describe anything small that's dependent on something larger. The small satellite circles around the more powerful force, like a moon orbiting a planet. Satellite can describe a small country — a satellite country — controlled by a larger one, or a large organization that has a small office — a satellite office — in another location.
