MOONS OF ALL THE PLANETS

Do you know all 294 moons of the planets (and dwarf planets) in our solar system? Well here they are! Every so often new moons are discovered for Jupiter and Saturn. Moons are listed by size from largest to smallest for a given planet.

Planet Mercury is too close to the Sun to hold on to a moon.

Planet Venus may have had a moon in the distant past, which collided with another object and then impacted Venus.

Planet Earth has a single, exceptionally large moon. Earth also has several quasi-satellites - asteroids 2020-CD3 and 2020-HO3 being the closest with the most stable temporary orbits.

Planet Mars has two small moons - both of which may be captured asteroids. Deimos and Phobos are very difficult to see except in large telescopes due to being so close to Mars. Moons are listed by size.

Dwarf planet Ceres located in the asteroid belt has no moons, which is surprising for its size.

Dwarf planet Hygiea in the asteroid belt also has no moon. However, a number of smaller asteroids (also called minor planets) do have moons, but they are all too faint to see in any amateur telescope.

Planet Jupiter has 92 known moons, and up to 600 tiny moons lurking around it. The four Galilean moons Ganymede, Callisto, Io, and Europa are large enough and bright enough to see in binoculars. Moons are listed by size. See also Moons of Jupiter for A-Z list and facts.

Planet Saturn has 145 known moons. The first 6 moons are viewable using a telescope, and the largest moon Titan, is visible through good binoculars. Saturn also has hundreds to thousands of moonlets embedded in its ring system. Moons are listed by size. See also Moons of Saturn for A-Z list and facts.

Planet Uranus has 27 known moons. The first 4 moons are viewable using a medium-to-large telescope. Moons are listed by size. See also Moons of Uranus for A-Z list and facts.

Planet Neptune has 14 known moons. The largest moon, Triton, is visible using a large telescope. Triton is a captured dwarf planet from the Kuiper Belt. Moons are listed by size. See also Moons of Neptune for A-Z list and facts.

Dwarf planet Pluto has 5 moons. Pluto and Charon are considered a binary dwarf planet system due to Charon's exceptionally large size. None of the moons are visible in any amateur telescope. Moons are listed by size. See also Moons of Pluto for A-Z list and facts.

Besides Pluto, there are 8 other dwarf planets in the Kuiper Belt that have 9 moons between them. Shown are each dwarf planet with it's moon, in order of moon size (largest to smallest). Note that these are all "almost certain" or "highly likely" to be dwarf planets. See also moons of dwarf planets for A-Z list and facts.
