Artist's concept comparing the size of the gas giant Jupiter (left) with that of the Earth (right). Jupiter's diameter is over ten times greater than the Earth's, it has over 300 times the mass, and is five times further from the Sun than the Earth. Jupiter is so large that its famous Great Red Spot (actually a giant, hurricane09/14/2009like storm that's at least 400 years old) would easily swallow the Earth. Jupiter spins so fast on its axis that it bulges noticeably at its equator (a day on Jupiter is about ten hours long).
