In our galaxy, there are stars and solar systems. There are comets, asteroids and a lot of solid material. There is also a lot of space between star systems. We call this space between star systems the Interstellar Medium. In this area, there are great clouds of gas and dust. They can range in size from a few light years to many thousands of light years across. Some even glow. They are nebulas.
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.
