I just realized, the gravity physics on the moon where the sameas the physics on earth... Thats kinda dumb, couldnt have been hard to tweek physics a little. On a side note, how do you explain this in the lore of destiny? I guess maybe the travler slightly terraforms each planet/ moon a little so maybe it gave the moon a little bit of an atmospher as well as adjusted the moons gravity? Watcha think. Also it must have pulled mars really closer cause its pretty visible from the moon.
