Why do lunar eclipse happen in a new moon?

Answer 1

The new moon is the monthly phase of the moon where it is completely unlit (or as near to being completely unlit as possible that month). If you think about it, this is going to happen when the moon is between the earth and the sun. New moon happens when it is as close as it can be to casting a shadow on the earth. The moon doesn't cast a shadow on the earth every month, because of the relationship of the orbits of earth and moon. Every now and then, the moon does cast a shadow on the earth at the time of new moon. When this happens, the moon is eclipsing the sun. There are several kinds of solar eclipse, and few things are as beautiful or as awesome as a total solar eclipse.

Answer 2

Solar eclipses can only occur at the time of New Moon. That's when the moon is between

earth and sun, and can be in position to block our view of the sun.

Lunar eclipses can only occur at the time of Full Moon. That's when the earth is between

sun and moon, and can be in position to block the moon's view of the sun.

Answer 3

"New Moon" is what we call it when the sun is more or less behind the moon in the sky. "Solar Eclipse" is what we call it when the moon casts a shadow on the Earth.

Answer 4

That's the only time when the moon is on-line between the Sun and Earth, so

it's the only time when the moon's shadow can hit the Earth's surface.

Answer 5

They do not. All lunar eclipses occur at the FULL moon, while all solar eclipses occur at the NEW moon.

The reason is the alignment of the Sun, Moon and Earth.

Answer 6

Solar eclipses do NOT happen at every full moon. Solar eclipses can ONLY happen at the full moon, but they only occur about twice a year.
