List of Natural Satellites

Natural satellites (moons) are quite common in our solar system. This is a comprehensive list of them.
== Moons by Primary ==
Mercury and Venus, both do not have moons, but Venus has been hypothesized to have a moon.
Earth has one moon, the moon, and some other temporary satellites, as well as space debris, satellites, etc orbiting it.
Mars has two moons, Phobos and Deimos, both named after the personifications of Fear and Dread. The two moons are irregularly shaped, and very small with miniscule gravity.
Jupiter has 95 moons with known orbits; 72 of them have received permanent designations, and 57 have been named. Its eight regular moons are grouped into the planet-sized Galilean moons and the far smaller Amalthea group. They are named after lovers of Zeus, the Greek equivalent of Jupiter. Among them is Ganymede, the largest and most massive moon in the Solar System. Its 87 known irregular moons are organized into two categories: prograde and retrograde. The prograde satellites consist of the Himalia group and three others in groups of one. The retrograde moons are grouped into the Carme, Ananke and Pasiphae groups.
Saturn has 146 moons with known orbits; 66 of them have received permanent designations, and 63 have been named. Most of them are quite small. Seven moons are large enough to be in hydrostatic equilibrium, including Titan, the second largest moon in the Solar System. Including these large moons, 24 of Saturn's moons are regular, and traditionally named after Titans or other figures associated with the mythological Saturn. The remaining 122 are irregular, and classified by their orbital characteristics into Inuit, Norse, and Gallic groups, and their names are chosen from the corresponding mythologies the groups are named after. The rings of Saturn are made up of icy objects ranging in size from one centimetre to hundreds of metres, each of which is on its own orbit about the planet. Thus a precise number of Saturnian moons cannot be given, as there is no objective boundary between the countless small anonymous objects that form Saturn's ring system and the larger objects that have been named as moons. At least 150 "moonlets" embedded in the rings have been detected by the disturbance they create in the surrounding ring material, though this is thought to be only a small sample of the total population of such objects.
Uranus has 27 moons, 5 of them are known to be in hydrostatic equilibrium, the remaining 22 are small, 13 are small inner ring shepherds, the rest (nine) are irregular moons. Unlike other planetary moons (that are named from antiquity), Uranus's are named after characters in pieces written by Alexander Pope or Shakespeare. Uranus's major moons: Miranda, Ariel, Umbriel, Titania, and Oberon, are all in hydrostatic equilibrium. Titania, the largest is the 15th largest moon in the solar system.
Neptune has 14 moons, 1 of them (Triton) is in hydrostatic equilibrium. Triton is unique because it is a planetary size object and it has a retrograde irregular orbit. This could mean that Triton is a captured dwarf planet from the Kuiper Belt. The remaining 13 of the moons are either prograde inner moons or small, outer retrograde moons.
Pluto has 5 moons. 1 (Charon) is in hydrostatic equilibrium, and is in a binary system with Pluto. The remaining 4 are small and orbit the binary system.
Haumea has 2 moons, both rather small. They are named Namaka and Hi'iaka. As well as the small moons, Haumea has a thin ring system orbiting it. This could mean shepherd moons embedded in the rings, but none of these have been found.
Makemake and Eris both have one moon. Makemake's has no name (S/2015 (136472) 1), while Eris has its moon named Dysnomia.
A number of other objects in the Kuiper belt and scattered disk may turn out to be dwarf planets. Orcus, Quaoar, Gonggong, and Sedna are generally agreed to be dwarf planets among astronomers, and all but Sedna are known to have moons. A number of other smaller objects, such as Salacia, Varda, and 2013 FY₂₇, also have moons, although their dwarf planethood is more doubtful. This list includes all objects with best estimated diameter above 700 km, including 2003 AZ₈₄ whose satellite has not been seen since its initial discovery.
As of October 2022, 365 asteroid moons and 128 trans-Neptunian moons (including those of Pluto and the other dwarf planets) had been discovered.
