The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. Jupiter’s mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth’s diameter. (Jupiter's Great Red Spot, even at its current diminished size, spans 15,900, just over a full Earth diameter.) Jupiter is 2½ times more massive than the rest of the planets in the solar system combined. Despite its bulk, though, Jupiter has a fast rotation period of just 10 hours!
Oh my God too much longest...
