Irregular moons are probably minor planets that have been captured from surrounding space. Most irregular moons are less than 10 kilometres (6.2 mi) in diameter. The earliest published discovery of a moon other than Earth's was by Galileo Galilei, who discovered the four Galilean moons orbiting Jupiter in 1610. Over the following three ...
The name of Pluto 's moon Charon was suggested by James W. Christy, its discoverer, soon after its discovery. The other four moons are named Hydra, Nix, Kerberos, and Styx . Charon, Hydra, Nix, and Kerberos are all characters in Greek mythology, with ties to Hades (the Greek equivalent of Pluto).
Claimed moons of Earth. This asteroid's orbit keeps it near the Earth, but not orbiting it in the usual sense. When analyzing its orbit from the perspective of different bodies, the presumed quasi-satellite does seem to have a more stable location near the Earth. The orbit of 2020 CD 3 around the Earth. The gray band is the orbit of the Moon.

This list is not comprehensive, and does not list the highest places on the Moon. Clementine data show a range of about 18,100 meters from lowest to highest point on the Moon. The highest point, located on the far side of the Moon, is approximately 6500 meters higher than Mons Huygens (usually listed as the tallest mountain).
