Document Summary
It"s radius is almost at it"s maximum for a jovian planet: jupiter does not have a solid surface. It is very dense, hot hydrogen and helium that has been compressed into liquid and metallic phases. The planet is seen to be all atmosphere, but the pressure and temperature increase the farther in, so an airplane could not just fly though: it does still have distinct inner layers, farthest outside is the gaseous hydrogen. These core"s are not as compressed so they hydrogen compounds surround a layer of rock and metal: jupiter has the strongest magnetic field by far, about 20,000 times stronger than earth"s. The metallic hydrogen layer is the cause of it. Io, it"s most volcanically active moon, is responsible for many of the charged particles: the other three jovian planets have magnetospheres as well, but they range between much stronger than earth"s and weaker than.
