Full Moon
The Moon shows its full face to Earth once a month — well, sort of. In fact, the same side of the Moon always faces the planet, but part of it is usually in shadow. Most of the time, the "full moon" is not perfectly full. Only when the Moon, Earth, and the Sun are perfectly aligned is the Moon 100% full, and this alignment produces a lunar eclipse. Occasionally — once in a blue moon — the Moon is full twice in a month (or four times in a season, depending on which definition you prefer).
