Terrestrial planets in general are solid, or solid with a liquid core. Gaseous planets in general are liquid, or liquid with a solid core.
Can there be planetoids with substantial alternating layers of solid - liquid - solid, or liquid - solid - liquid? (I do not consider Earth's hydrosphere as substantial in this regard.) I believe there are some known moons which qualify.
