Saturn is known to contain metallic hydrogen, an unusual form of hydrogen that behaves like a metal under the extreme pressures and temperatures found in the planet's interior. This state of hydrogen is thought to contribute to Saturn's strong magnetic field. Additionally, trace amounts of other metals, such as sodium and potassium, may also be present in the atmosphere.
