Jupiter

Jupiter

A giant mass of predominantly hydrogen and helium, Jupiter dwarfs the other planets in our Solar System with a mass is 2.5 times larger than that of all of the other planets combined. NASA’s spacecraft Juno is on a mission at Jupiter to deepen our understanding of how such giant planets were formed. Recently 12 new moons have been spotted orbiting Jupiter bringing the total number of Jovian moons to 79, the first four of these moons were observed in 1610 by Galileo Galilei and have captivated our interest ever since.

Why does Jupiter spin so fast?

It's our Solar System's largest planet, and also the dizziest.
