The known icy moons in this range are all ellipsoidal (except Proteus), but trans-Neptunian objects up to 450–500 km radius may be quite porous. [10] For simplicity and comparative purposes, the values are manually calculated assuming that the bodies are all spheres. The size of solid bodies does not include an object's atmosphere.
[37] [2] These discoveries brought Saturn's total number of confirmed moons up to 145, making it the first planet known to have over 100 moons. [ 37 ] [ 38 ] [ 39 ] Yet another moon, S/2006 S 20 , was announced on 23 May 2023, bringing Saturn's total count moons to 146. [ 2 ]

The first full moon of 2024 will rise on Jan. 25 at 12:54 p.m. EST. Traditionally known as the Wolf Moon because of a greater chance of hearing wolves howling during that time, according to the ...
The surface of Proteus is heavily cratered and shows a number of linear features. Its largest crater, Pharos, is more than 150 km in diameter. [6] [23] All of Neptune's inner moons are dark objects: their geometric albedo ranges from 7 to 10%. [25]
A montage of Jupiter and its four largest moons (distance and sizes not to scale) There are 95 moons of Jupiter with confirmed orbits as of 5 February 2024. [1] [note 1] This number does not include a number of meter-sized moonlets thought to be shed from the inner moons, nor hundreds of possible kilometer-sized outer irregular moons that were only briefly captured by telescopes.

The Moon is Earth's only natural satellite.It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
