Lunar Eclipse. A lunar eclipse occurs when the Earth's shadow falls on the Moon, and a solar eclipse occurs when the Moon's shadow falls on the Earth. A look at the geometry of Moon phases would make it appear that a lunar eclipse should happen at every full moon and a solar eclipse at every new moon. This does not occur because the plane of the Moon's orbit is tilted 5.2Â° with respect to the plane of the Earth's orbit around the Sun (the ecliptic plane).
Lunar eclipses occur when Earth's shadow blocks the sunâs light, which otherwise reflects off the moon. There are three types â total, partial and penumbral â with the most dramatic being a total lunar eclipse, in which Earthâs shadow completely covers the moon.artial lunar eclipse: Some eclipses are only partial. But even a total lunar eclipse goes through a partial phase on either side of totality. During the partial phase, the sun, Earth and moon are not quite perfectly aligned, and Earthâs shadow appears to take a bite out of the moon.
