Names of all the Planets of the Solar System
This page shows the names of all the planets and also the names of the currently known moons.
It also lists the names and locations of each Planet and Satellite discoverer (if known)
and provides the meaning/derivation for each name.
The planets are in order of the date of discovery.
Planet and Satellite Names and Discoverers
This page shows information about planetary bodies named by the IAU Working Group for Planetary System Nomenclature (WGPSN), and about bodies named by the IAU Committee on Small Body Nomenclature that have surface features named by the WGPSN.
Satellites in the saturnian system are named for Greco-Roman titans, descendants of the titans, the Roman god of the beginning, and giants from Greco-Roman and other mythologies. Gallic, Inuit and Norse names identify three different orbit inclination groups, where inclinations are measured with respect to the ecliptic, not Saturn's equator or orbit. Retrograde satellites (those with an inclination of 90 to 180 degrees) are named for Norse giants (except for Phoebe, which was discovered long ago and is the largest). Prograde satellites with an orbit inclination of around 36 degrees are named for Gallic giants, and prograde satellites with an inclination of around 48 degrees are named for Inuit giants and spirits.
Note: 20 new moons discovered in 2019 and we are awaiting the official names to be selected before updating the table below.
Pluto and its Moons
Satellites in the plutonian system are named for characters and creatures in the myths surrounding Pluto (Greek Hades) and the classical Greek and Roman Underworld.
