Moons Of All The Planets
Know all 219 known moons of all the planets in our solar system? Well here they are! Every so often new moons are discovered for Saturn and the dwarf planets. (m = apparent magnitude)
☿ Mercury Moons = 0
Mercury is too close to the Sun to hold on to a moon.
♀ Venus Moons = 0
Venus may have had a moon in the distant past, which collided with another object and then impacted Venus.
♁ Earth Moons = 1
Earth also has several quasi-satellites - asteroids 2020 CD3 and 2020 HO3 being the closest with the most stable temporary orbits.
♂ Mars Moons = 2
Both moons of Mars may be captured asteroids, and can be viewed in small (4-inch) telescopes.
- ASTEROID BELT REGION -
⚳ Dwarf Ceres Moons = 0
Ceres is the only dwarf planet located in the asteroid belt and has no moons surprisingly. A number of smaller asteroids (also called minor planets) do have moons, but they are all too faint to see in any amateur telescope. Notable asteroids with moons include:
Sylvia with 2 moons Romulus & Remus; Eugenia with 2 moons Petit-Prince & S\2004; Daphne with moon Peneius, Kalliope with moon Linus; Minerva with 2 moons Aegis & Gorgoneion; Kleopatra with 2 moons Alexhelios & Cleoselene; and Ida with moon Dactyl.
- OUTER SYSTEM REGION -
♃ Jupiter Moons = 79
Moons of Jupiter are listed in order of size. The first 4 moons listed, the Galilean moons, are viewable naked eye under dark skies, while Amalthea can be be viewed in a 8-10-inch telescope.
♄ Saturn Moons = 82
Moons of Saturn are listed in order of size. The first four moons are viewable with good binoculars and the next four moons with a 4- to 8-inch telescope. Saturn also has hundreds to thousands of moonlets embedded in its ring system.
S/2006 S 1
S/2006 S 3
♅ Uranus Moons = 27
Moons of Uranus are listed in order of size. The first 4 moons can be viewed in medium-sized (8- to 10-inch) telescopes.
♆ Neptune Moons = 14
Moons of Neptune are listed in order of size. Triton is viewable using a medium-sized (10-12 inch) telescope. Triton is believed to be a dwarf planet from the Kuiper Belt captured by Neptune.
- KUIPER BELT REGION -
♇ Dwarf Pluto Moons = 5
Moons of Pluto are listed in order of size. Pluto and Charon are considered a binary dwarf planet system. None of the moons are visible in any amateur telescope. Pluto however, at current magnitude 14, is viewable in 12-inch and larger telescopes.
Dwarf Orcus Moons = 1
Dwarf Salacia Moons = 1
Dwarf Haumea Moons = 2
Dwarf Quaoar Moons = 1
Dwarf Makemake Moons = 1
Dwarf Varda Moons = 1
Dwarf Gonggong Moons = 1
Dwarf Eris Moons = 1
- INNER OORT CLOUD REGION -
Planets here are in very elongated orbits that go from the Kuiper Belt out to the inner edge of the Oort Cloud. Several dwarf planets out there are believed to be perturbed by Planet 9, thought to be a mini-Neptune planet at 10X Earth mass. It's existence is highly probable but not yet confirmed.
