The International Astronomical Union officially named these moons Nix (Pluto II, the inner of the two moons, formerly P 2) and Hydra (Pluto III, the outer moon, formerly P 1), on 21 June 2006. [4] Kerberos, announced on 20 July 2011, was discovered while searching for Plutonian rings.
Trojan moons are a unique feature only known from the Saturnian system. A trojan body orbits at either the leading L 4 or trailing L 5 Lagrange point of a much larger object, such as a large moon or planet. Tethys has two trojan moons, Telesto (leading) and Calypso (trailing), and Dione also has two, Helene (leading) and Polydeuces (trailing). [23]

In 2021, Scott S. Sheppard and colleagues used the Subaru Telescope at Mauna Kea, Hawaii and discovered two more irregular moons of Neptune, which were announced in 2024. [12] These two moons are provisionally designated S/2021 N 1 and S/2002 N 5. The latter turned out to be a recovery of the lost moon from 2002. [2] [13] Discovery of outer ...
Mars may have had a single moon before something smashed into it, tearing it asunder into the two moons we see today. In a study published Monday in Nature, scientists explained how they used the ...
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 ...
