< Planets | Geology

Planetary geology is a lecture from the school of geology and the department of radiation astronomy of the school of physics and astronomy. It is about the geological effects on large rocky objects due, or apparently due, to being in orbits around a star or stellar system within a few light years.

Main resource: Hypotheses
  1. The effects on large rocky objects of having orbits around stars or stellar systems can be muted by rotation.
