Everything about Jupiter is large. It is so big that it could easily swallow all of the other planets (or more than 1,300 Earths). It also weighs more than twice as much as all the other planets. Despite its huge size, Jupiter is the fastest-spinning planet, rotating once in less than 10 hours. Jupiter is a giant ball of gas, with no solid surface. It is mainly made of the very light gases, hydrogen and helium.
