Moons Of All The Planets
Know all 203 known moons of all the planets in our solar system? Well here they are! Every so often new moons are discovered for the outer dwarf planets. (m = visual 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 has several quasi-satellites - asteroid 2016 HO3 is the closest with the most stable orbit.
♂ Mars Moons = 2
Both moons of Mars may be captured asteroids, and can be viewed in small (4-inch) telescopes.
⚳ Dwarf Ceres Moons = 0
Ceres is the only dwarf planet located in the asteroid belt and has no moons surprisingly. A number of asteroids (also called minor planets) do have moons.
♃ 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 8- to 10-inch telescopes.
♄ Saturn Moons = 62
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.
♅ 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 (8-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 10-inch and larger telescopes.
Dwarf Orcus Moons = 1
Dwarf Haumea Moons = 2
Dwarf Quaoar Moons = 1
Dwarf Makemake Moons = 1
Dwarf 2007 OR10 Moons = 1
Dwarf Eris Moons = 1
Dwarf Salacia 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.
