Natural Satellites
A natural satellite, also called a moon, is a solar system body that orbits another solar system body that is not the Sun. The body being orbited can be a planet, minor planet or comet. Natural satellites are typically smaller than the body being orbited, but the size can vary within this constraint. With Wolfram|Alpha, you can explore the full set of natural satellites, which range in size from a mile or so in diameter to the size of Mercury or larger. The orbits of natural satellites can be prograde or retrograde and circular or elliptical, and their rotation may be constrained by tidally locking to the object they orbit. Some natural satellites have significant atmospheres.
