Perigee and apogee. The moon satellite

The full moon in its perigee (the closest point of its orbit) and its peak (the farthest). The photo shows a comparison between the different sizes visible from Earth.

This illustration, based on the images of the Galileo probe, shows the approximate difference in the apparent size between a full moon in perigee (on the left) and the full moon at its peak (on the right), the furthest points in the lunar orbit

The Earth and the Moon are a little closer during winter in the northern hemisphere. Between the furthest possible point and the closest one there may be a 20% difference in the luminosity of the Moon. The difference may not be detected by the human eye.
