What is the origin of 'sleep tight'? One of the mysteries of the English language finally explained.
The moon doesn't glow in a very real sense. It reflects the Sun's light. (Or the Earth's light if you're not on Earth and in the right position.) As Quora User says, the moon has a high albedo. So it reflects pretty well.
So-called moonshine is simply light reflected or re-emitted from the moon and this radiation serves to heat the earth slightly. This also varies with the phases of the moon during the month. This extra radiation is just 10**-5 that of the direct solar energy so this also gives a roughly 0.01-0.02 degree effect. 3) Stabilising the Earthâs axis. It seems likely that without the moonâs stabilising gyroscopic effect the earthâs axis would be more chaotic.
