Moon
From Destinypedia, the Destiny wiki
Luna is Earth's moon. Like just about every body in the Solar System, itis littered with the debris of man's golden age. The surface of Luna apears to be shattered, with giant rifts in the ground and massive chunks tilted upward. One location on the moon is known as Hellmouth, a massive hole that goes deep into the planet. It is unknown what, if any, amount of combat takes place on Luna.
