You might decide to visit the moons instead. One of the four largest moons is Callisto. Callisto is not made of gas. It is solid. The ground is covered with ice and many, many craters.
Craters are like the footprints of meteorites that crash from the sky.
Callisto's craters are mysterious. There is no rain or wind to wear away the craters. You can not really travel that far to find out. However, a space probe is making the trip for you. A probe is like a remote control car or airplane.
