How does a lunar eclipse?

Answer 1

An eclipse occurs on those times when the moon moves into a position of direct alignment with sun and the earth. There are 2 types of eclipse lunar and solar. When the full Moon passes through the shadow of the Earth. In this case, the Sun and the Moon are on opposite sides of the Earth. If you observe a lunar eclipse (visible only at night at the time of certain full Moons), you'll see the bright lunar disk turn dark sometimes a coppery red color.
