14 Fun Facts About the Ring Moons of Jupiter: A 15-Minute Book
by Jeannie Meekins
There are eight regular satellites in orbit around Jupiter. These are moons that formed within the gravity field of Jupiter. They were formed at the same time and out of the same material as the planet itself. They have circular orbits and orbit in the same direction as the planet. This book is about the four, small ring moons. These little known moons are odd shaped and orbit close to the planet.
