Question

When does a lunar eclipse take place? Does it occur on every full moon’s night?

Answer 1

A lunar eclipse occurs when the earth comes between the sun and the moon and casts its shadow on moon. On the full moon night, the moon rises in the east after the sun sets in the west. On such a night, the sun and moon are on the opposite sides of the earth. The shadow of the earth falls on the surface of the moon therefore the moon is not visible to us.
