[[Image:Moons of solar system v7.jpg|thumb|300px|Selected moons, with the Earth to scale. Nineteen moons are large enough to be round, and one, Titan, has a substantial atmosphere.]] [[Image:Moons vs time.SVG|thumb|300px|The number of moons discovered in each year]] This is a '''list of moons''' known to humans, also known as [[natural satellite]]s, that are within the [[Solar System]]. They are grouped into sections based on their ''primary'', the [[planet]] or [[dwarf planet]] around which they orbit. Satellites large enough for their gravity to have given them a near-spherical or ellipsoidal shape have their names in '''bold'''. The earliest discovery of a moon other than our own was by [[Galileo Galilei]], who discovered the four [[Galilean moons]] in 1610. Over the following three centuries only a few more moons were discovered. Missions to other planets in the 1970s, most notably the [[Voyager 1]] and [[Voyager 2|2]] missions, saw a surge in the number of moons detected. In recent years many more new moons have been discovered, mostly by large ground-based [[optical telescope]]s. See [[Timeline of discovery of Solar System planets and their moons]] for more information. The list below contains all moons discovered prior to [[2008]]. Various [[asteroid]]s are [[binary asteroid]]s or have [[Asteroid moon|satellites]] orbiting them. These are not listed here; see [[List of asteroid moons]]. == Mercury == [[Mercury (planet)|Mercury]], the innermost planet, has no moons larger than 1.6&nbsp;km.<ref name="mercury_no_moons">{{cite journal | url=http://adsabs.harvard.edu/abs/2007P&SS...55.2037W | title=A search for natural satellites of Mercury | last=Warell | first=J. | coauthors=Karlsson, O. | year=2007 | journal=Planetary and Space Science | volume=55 | issue=14 | pages=2037–2041 | doi=10.1016/j.pss.2007.06.004}}</ref> Note that for a brief time in 1974, Mercury was thought to have a moon; see [[Mercury's moon]]. == Venus == [[Venus]] has no moons.<ref name="venus_no_moons">{{cite web | url=http://solarsystem.nasa.gov/planets/profile.cfm?Object=Venus&Display=Moons | title=Solar System Exploration: Planets: Venus: Moons | publisher=NASA | accessdate=2008-03-16}}</ref> == Earth == [[Earth]] has one natural satellite, the [[Moon]].
