A Satellite is any object orbiting another body.

Natural satellites include moons. Artificial satellites are human-made and power modern navigation, weather forecasting, TV distribution, and global communications.

A lot of what we call modern infrastructure quietly depends on satellite systems being up.

Satellite radio signals also pass through the [[Ionosphere]], which can introduce timing error and distortion that receivers have to compensate for.
