All Moons of Jupiter
Most of Jupiter's swarms of smaller moons orbit much farther out than the Galilean satellites. Of these distant moons, the larger ones may be captured asteroids. The smaller ones are likely fragments from massive collisions.
Quick Facts
Galileo Galilei spotted the first Jupiter moons in 1610 with a new invention called a telescope.
German astronomer Simon Marius found Jupiter's moons about the same time as Galileo, but Galileo was first to report the moons and is credited with their discovery.
Modern astronomer Scott S. Sheppard has discovered the most moons of Jupiter, including nine in 2017 alone.
