What are the major moons for each planet?

Answer 1

Mercury and Venus lack moons.

The moon (aka Luna) is Earth's moon.

Mars has Phobos and Deimos, both of which are tiny, essentially captured asteroids.

Jupiter has four primary moons, Europa, Ganymede, Io, and Callisto and 63 others. Ganymede is the largest moon in our solar system.

Saturn's primary moon is Titan. Titan is unusual in that it has a notable atmosphere, even thicker than our own.

Uranus has Miranda, Ariel, Umbriel, Titania, and Oberon. Five major moons.

Neptune has one primary moon, Triton, and a dozen smaller ones.

The dwarf planet Pluto has Charon, a co planet, and two little moonlets roughly similar in size (but not composition) to the Martian moons.
