How many times does a lunar eclipes happen every year??
A lunar eclipse occurs during a Full Moon when the Earth is between the Sun and the Moon and when the Moon passes through some of the Earth’s shadow. The Earth’s shadow has two parts: Umbra – dark inner shadow. Total lunar eclipses occur when the entire Moon passes through the umbral shadow. Partial lunar eclipses occur when only a portion of the Moon passes through the umbral shadow. Penumbra – faint outer shadow. Penumbral lunar eclipses occur when the Moon passes through the penumbral shadow but are very difficult to observer so are of internest mainly to astonomers.
