Mundicide

Mundicide was a term used for the destruction of a planet or similar celestial object. Various degrees of mundicide occurred throughout history; causes ranged from supernovas, superlasers such as the Galaxy Gun or the Death Star, gravitational weaponry such as Centerpoint Station, or other superweapons. Some planets, while not completely destroyed, were rendered completely uninhabitable, such as Caamas and Uphrades. If a planet was deliberately destroyed, like in the case of the Destruction of Alderaan, it can sometimes be comparable to Speciecide due to wiping out a significant portion of the planet's population.
