Total lunar eclipse geometry, computer artwork. A lunar eclipse occurs as the Moon passes into the Earth's shadow. Lunar eclipses occur only at full Moon, and then only when the Earth and full Moon are correctly aligned (about 2-3 times a year). The Moon's speed through the shadow is about one kilometer per second, and totality may last up to 107 minutes.
