Timeline of natural satellites in the Solar system by decade of discovery

For comparison, discovery dates of Uranus, Neptune and Pluto 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.

Historically the naming of natural satellites did not always match the times of their discovery. See Naming of natural satellites.
