Moon List — Астрологическая энциклопедия ZEUS

List of the 97 satellites of the Solar System

This moon list was last updated April 16, 2001 . This list includes both planetary satellites and asteroidal companions. Note that because some were only recently discovered, some have missing information.

For your information: 26 moons were discovered in 2000, breaking the record for the most moons discovered in one year, beating out 1986, when Voyager 2 discovered 9 moons of Uranus. 12 Saturnian moons have been discovered; 11 Jovian moon has been discovered with one more found to be a moon, not an asteroid (but was discovered in 1999); 1 moon of Pulcova was discovered; 1 moon of 2000 DP107 was discovered. Finally, the first moon of a TNO was discovered. Two so far have been discovered in 2001, both moons of asteroids.
