Earth
All terrestrial planets, such as Earth, Mercury, Venus, and Mars, have inner and outer cores. These cores are composed of mostly iron and nickel, with the inner core being solid and the outer core in a liquid state. Gas giant planets like Jupiter and Saturn also have cores, but they lack a distinct separation into inner and outer regions like terrestrial planets.
