mercury has an observed magnetic field, which is believed to be generated within its metallic core. mercury's core occupies 85% of the planet's radius, making it the largest core relative to the size of the planet in the solar system; this indicates that much of mercury's surface may have been lost early in the solar system's history. mercury has a solid silicate crust and mantle overlying a solid iron sulfide outer core layer, followed by a deeper liquid core layer, and then a possible solid inner core making a third layer.
