The Moon is Earth's only natural satellite. At about one-quarter the diameter of Earth (comparable to the width of Australia), it is the fifth largest satellite in the Solar System, and the largest satellite relative to its prime planet within the Solar System, and larger than any known dwarf planet (including Pluto). It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth that of Earth. Jupiter's moon Io ("EYE-oh") is the only satellite in the Solar System known to have a higher surface gravity and density.
