Factoid

Biggest ocean of our solar system is on Jupiter –not of water but metallic hydrogen. Jupiter retained a higher level of hydrogen and helium than earth when it was formed because of its distance from the sun. Its orbit is five times further from the sun compared with the earth. Because of its chemical composition and mass, way down the cold clouds pressure rises to the point that hydrogen turns into liquid and forms an ocean of liquid hydrogen. Computer models show not this is the largest ‘known’ ocean in the solar system, but could also be about 40,000 km deep – roughly as deep as the earth is around!
