The red spot on Jupiter also known as The Great Red Spot, is so enormous that it could fit three Earths inside.
"Best planet to learn about!" - Tim
Since Jupiter is one of the gas giants, we have not found a way yet to send a human into Jupiter but we hope it may happen in the future.
Jupiter's mass is 318 times Earth's mass and Jupiter is 2.5 times more giant than all of the other planets in our solar system. Jupiter is so large that if it gained much more mass it would shrink. More mass would make the planet more dense and it would start pulling on itself. Astronomers estimate that Jupiter could have 4 times it's mass and still remain the same size.
