Document Summary
Jupiter and saturn are mostly made up on h and he and uranus and neptune are mostly made of hydrogen compounds. Uranus and neptune are denser due to having less h/he and more rock and hydrogen compounds. Jupiter is the exception because it"s density is similar to uranus and neptune but has a lot more h/he. Jovian planets rotate faster than terrestrial planets not quite spherical due to this. Formed in the outer range of the solar system cold enough for hydrogen compounds to condense. Many more hydrogen compounds than metal and rock so jovian planets grew to be very big. Most distant planets ended up smaller because they had less time to capture gas. Jupiter"s core made of rock, metal, helium, and hydrogen compounds core is size of. Jupiter has a strong coriolis effect due to large size and fast rotation circulation cells split into many bands instead of just three.
