Due to centrifugal and centripetal forces between the Earth and Moon, Moon revolves around the Earth. Similarly, These centrifugal and centripetal forces cause the Earth to revolve around the Sun. This helps us to study the day, date and year we will live in the present scenario. It takes 365 and 1/2 days to complete one revolution earth around the Sun is not in a perfectly circular path but in an elliptical path. This is the reason why earth experience climatical changes. It Takes 27 days to Moon to revolve around the earth. This is why sometimes the moon appears as Crescent moon in some days due to the shadow of the earth which falls on the moon and some part of the light from the sunlight falls on the moon.
In this Eclipse Phenomenon, These are of two types. They are:
(i) Solar Eclipse
(ii) Lunar Eclipse
During the Solar Eclipse, Moon comes to a position where it completely covers the earth with its shadow which is projected towards the Earth and does not allow the sunlight to fall on the earth and makes the Sun disappear at the daytime. Here, the Moon is located exactly at the middle of the Sun and Earth but for only a short period of time.
During the Lunar Eclipse, Earth comes to a position where it completely covers the moon with its shadow which is projected towards the Moon and does not allow the sunlight to fall on the moon and makes the Moon disappear at the nighttime. Here, the Earth is located exactly at the middle of the Sun and Moon but for only a short period of time.
