Distinguishing features: Much of the mystery surrounds Jupiter's interior. From the planet's mass, density, and magnetic field, scientists surmise that it probably has a dense core of rock and metal at least 10 times as massive as Earth. A thick layer of hydrogen surrounds the core. Jupiter's gravity squeezes this layer so tightly that it acts as a metal. The metallic hydrogen probably rotates at a different speed from the core, so it produces a "dynamo" effect, generating electric currents that create Jupiter's magnetic field.
