Changes

The exciting thing about Jupiter is that usually you will see two, three, or four little "stars" near it that are all lined up in a straight line, with each other, and with Jupiter. If you watch it night after night, these "stars" will change their position relative to Jupiter, but you almost always will see several of them and they will always be lined up. These are four of the satellites of Jupiter.
