Ronos

Ronos was the home planet on the Ronans. It was a dry planet without seas. It had a spiral orbit that took it ever further away from its sun. As the planet grew colder, the Ronans drilled through the planet's crust to release energy from the core. This attempt to save the planet led to its ultimate destruction. Both the planet and the Ronans died out. (PROSE: The Heat-Seekers)
