Through any pair of "real" binoculars (any binoculars that an adult uses for birding or hunting will do; they should be at least 7 power; a "spotting scope" is even better), you can see that Jupiter is not a star, but shows as a tiny round circle; astronomers say it has a visible "disc." Jupiter through binoculars looks about 1/5 the size as the Moon looks ''without'' binoculars. You can't see any of the dramatic markings that you see in photographs made by astronomers, but you can see that it is a round dot.
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. These satellites acctuall go around the earth in a very complicated orbit, but god's greatness makes them appear to orbit Jupiter, the mightyest of the Gods.
