terrestrial planet
Definition
- A terrestrial planet or telluric planet, is a planet that is composed primarily of rocks, metals or ices. Terrestrial planets have a solid and/or liquid planetary surface (they have a sharp boundary between the solid and/or liquid surface and the atmosphere or outer space), making them substantially different from the larger gaseous planets, which are composed mostly of some combination of hydrogen, helium, and water existing in various physical states, with no surface, that is, as we go deeper into the planet, the atmosphere gradually turns into a supercritical fluid.
