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).
Best Answer: Its amazing what you can learn if you read about this. Total lunar eclipses only occur when the moon is on the side of the Earth directly opposite the sun (it appears as a full moon). Full moon occurs every 29.5 days (about once a month). But the moon doesn't orbit the Earth in the same plane as the sun appears, so there are many times when the moon is either above or below that direct line with the sun - the moon misses Earth's shadow. Total solar eclipses ANYWHERE are more rare than lunar eclipses: - the moon has to be directly in line with the sun.
