Explanation:
An lunar eclipse occurs when the Earth comes in between the Sun and the moon when all the three are aligned in space and the Earth casts its shadow on the phase of the full moon and thus darkens it usually the moon turns into a shade of copper red.
For the eclipse to occur every month the Earth's orbit around the sun must coincide with the moon's orbit around the earth.
It takes about a month for the moon to orbit the Earth and if the plane of the ecliptic orbit is the same as that of the orbit of the moon around the earth then there would be at least two lunar eclipses in a month, one at full moon and the other one fortnightly.
