Timeline of natural satellites

     From Wikipedia, the free encyclopedia.

Timeline of natural satellites in the Solar system by decade of discovery For comparison, discovery dates of Uranus and Neptune are also included, as well as the first six asteroids. After the first six, new asteroids were discovered every year; however, the first four at least were for several decades considered full-fledged planets.
