There are 293 confirmed moons in our cosmic neighborhood. By studying these worlds, astronomers hope to learn about ancient asteroid collisions, space volcanoes, and the origins of life itself.
Eventually, new moons were discovered also around Uranus starting in 1787 by Herschel, [23] around Neptune starting in 1846 by William Lassell [24] and around Mars in 1877 by Asaph Hall. [25] Further apparent discrepancies in the orbits of the outer planets led Percival Lowell to conclude that yet another planet, "Planet X", must lie beyond ...
