In astronomy, the blocking out of light from one object by the intervention of another object. The most dramatic eclipses visible from the Earth are eclipses of the sun (when sunlight is blocked by the moon) and eclipses of the moon (when sunlight on its way to the moon is blocked by the Earth).

A lunar eclipse: occurs when the Earth passes between the Sun and the Moon and Earth’s shadow is cast upon part or all of the Moon
