About
PROTO-PLANET: Proto-planets are small celestial objects that are the size of a moon or a bit bigger. They are small planets, like an even smaller version of a dwarf planet. Astronomers believe that these objects form during the creation of a solar system. CRYOVOLCANO: A Cryovolcano (as known as ice volcano) is a type of volcano that erupts volatiles such as water, ammonia or methane, instead of molten rock. |
