Moons are usually the satellites that come to mind. Since you're asking for a list of uses, I assume you're referring to the man-made type of satellites. Satellites basically orbits around a planet and carry out specific functions. Some, like the space station, can even house people for months and years.
Here is a list of the different types of satellites and their functions.
* Anti-Satellite weapons/"Killer Satellites" are satellites that are armed, designed to take out enemy warheads, satellites, other space assets.
* Astronomical satellites are satellites used for observation of distant planets, galaxies, and other outer space objects.
* Biosatellites are satellites designed to carry living organisms, generally for scientific experimentation.
* Communications satellites are satellites stationed in space for the purpose of telecommunications.
* Miniaturized satellites are satellites of unusually low weights and small sizes.
* Navigational satellites are satellites which use radio time signals transmitted to enable mobile receivers on the ground to determine their exact location.
* Reconnaissance satellites are Earth observation satellite or communications satellite deployed for military or intelligence applications.
* Earth observation satellites are satellites intended for non-military uses such as environmental monitoring, meteorology, map making etc. (See especially Earth Observing System.)
* Space stationsare man-made structures that are designed for human beings to live onin outer space. Space stations are designed for medium-term living in orbit, forperiods of weeks, months, or even years.
* Tether satellites are satellites which are connected to another satellite by a thin cable called a tether.
* Weather satellites are primarily used to monitor Earth's weather and climate.
