The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...

The new discovery increases the moons orbiting the "jewel of our solar system" to 82, surpassing Jupiter
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.
NASA launched the New Horizon spacecraft in 2006 to learn more about the icy dwarf planet Pluto. Here are some of the first photos from that mission, taken from between 125 and 115 million miles away.
Over the following three centuries, only a few more moons were discovered. Missions to other planets in the 1970s, most notably the Voyager 1 and 2 missions, saw a surge in the number of moons detected, and observations since the year 2000, using mostly large, ground-based optical telescopes, have discovered many more, all of which are irregular.
Voyager 2 discovered previously unknown Neptunian rings, [64] and confirmed six new moons: Despina, Galatea, Larissa, Proteus, Naiad and Thalassa. [65] C ] While in the neighborhood of Neptune, Voyager 2 discovered the " Great Dark Spot ", which has since disappeared, according to observations by the Hubble Space Telescope . [ 66 ]
