The Moons of Other Planets• The Moons of Mars Mars’s two moons, Phobos and

Deimos, are small and dark.

• The Moons of Jupiter Jupiter has dozens of moons.(50 known, and 14 waiting conformation) Liquid water may lie beneath the icy surface of the moon Europa. Ganymede is the largest moon in our Solar system. In 1610, Galileo Galilei discovered the 4 largest moons of Jupiter using just a telescope.

• The Moons of Saturn Like Jupiter, Saturn has dozens of moons. (53 known and 9 waiting confirmation) Most of these moons are small bodies of mostly frozen water but contain some rocky material. Titan is the 2nd largest moon in our Solar system

The Moons of Other Planets, continued• The Moons of Uranus Uranus has several moons. (27

known) Uranus’s largest moons are made of ice and rock and are heavily cratered. Miranda is the most intriguing showing most signs of craters. Uranus’s moons are named after women in Shakespeare's plays and Alexander Pope’s poem.

• The Moons of Neptune Neptune has several known moons,(13 known) only one of which is large, Triton The large moon has a thin atmosphere of nitrogen.

• The Moon of Pluto Pluto has 3 moons the most known moon is Charon. Charon’s orbit is tilted relative to Pluto’s orbit.
