Of the Solar System's eight planets and its nine most likely dwarf planets, six planets and seven dwarf planets are known to be orbited by at least 300 natural satellites, or moons. At least 19 of them are large enough to be gravitationally rounded; of these, all are covered by a crust of ice except for Earth's Moon and Jupiter's Io. [1]
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 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 ...
Trojan moons Calypso and Telesto (trojans of Tethys), and Helene and Polydeuces (trojans of Dione). These small moons share their orbits with Tethys and Dione, leading or trailing either. [180] [181] Outer large satellites Rhea, Titan, Hyperion, and Iapetus. [179] Titan is the only satellite in the Solar System to have a substantial atmosphere ...
The Sun, planets, moons and dwarf planets (true color, size to scale, distances not to scale) The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly.
The mile-long Saturnian moon’s smooth body, free of any visible craters or pockmarks, may be made of ultralight ice crystals that act like a liquid. According to a 2013 analysis of Cassini data ...
Martian Moons eXploration (MMX) is a sample-return mission being developed by JAXA. The probe intends to launch in 2026, arriving at Mars by 2027 and collecting data about Phobos before collecting a surface sample from the moon and returning to Earth by 2031. A major goal of MMX is to better constrain the origins and history of Mars's moons. [48]
