Origins & Early Life

A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are colloquially referred to as moons, by analogy with the Moon, Earth's natural satellite. In English, the Moon with a capital M denotes Earth's satellite, while moon with a lowercase m is used generically for natural satellites.

Career & Major Achievements

In the Solar System, there are six planetary satellite systems, altogether comprising 456 natural satellites with confirmed orbits. Seven objects commonly considered dwarf planets by astronomers are also known to have natural satellites: Orcus, Pluto, Haumea, Quaoar, Makemake, Gonggong, and Eris. Including the aforementioned seven, there are 652 minor planets known or suspected to have natural satellites.

Enduring Legacy & Impact

The first known natural satellite was the Moon, but it was considered a "planet" until Copernicus' introduction of De revolutionibus orbium coelestium in 1543. Until the discovery of the Galilean satellites in 1610 there was no opportunity for referring to such objects as a class.
