About a billion years ago the moon was only about 200,000 Kilometers away from earth, instead of the now 384,000 Kilometers. It would have taken the moon 20 days to orbit the earth instead of over 27 days today. The tide would have been much stronger as well and during the full moon phase, you would not have needed sunglasses but the light reflected to the earth would have been immense. The moon's relationship with the earth is in constant change as the moon continues drifting away.
Until next moment,
