If that is true, then the Earth and the Moon should have the same average temperature, right? I mean, a big difference between the two is that the Earth has an atmosphere and the Moon has only a trace. Since their orbits around the Sun are roughly the same, they should get about the same amount of sunlight per square meter.

Granted, the albedo is not the same. The Moon has a significantly lower albedo than the Earth. That means for a given amount of sunlight, the average temperature of the Moon should be somewhat higher than the Earth.

But that isn't the case. Despite the greater amount of sunlight absorbed per unit area, the average temperature of the Moon is significantly lower. Because it doesn't have significant amounts of greenhouse gasses. Like CO2...
