Full Moon Perigee

This evening the Moon is full and at perigee. That means it is at the closest point in its orbit (the orbit of the moon is not a perfect circle) about the Earth. So if the Moon looks a bit bigger tonight, that is because it is bigger - about 14% bigger.

During the next new moon phase there will be a solar eclipse. It will be an annular eclipse where the Moon's disk will not completely cover the Sun's disk. The reason? The moon will be at its further point in its orbit about the Earth (the other side).
