Rocky Planet

(Terrestrial Planet, Telluric Planet)
(planet like Earth and Mars, mostly rock)

A Rocky Planet or Terrestrial Planet or Telluric Planet is a planet of mostly rock, like Mercury, Venus, Mars or Earth. Among Extra-Solar Planets, there are larger such planets, i.e., Super-Earths and Mega-Earths.

There is a presumed (and real?) correlation between rocky planets and how much Electromagnetic Radiation and Stellar Wind they are receiving, which is related to how close they are to the host star. A large would Atmosphere as per a Gas Giant would not last if too close (Photoevaporation).

There is presumed to be something of an upper limit on the size of rocky planets.
