The Earth moves round the Sun once every year, and the Moon moves around the Earth once every Lunar month.These movements of the Earth and the Moon bring about the most beautiful of celestial phenomenon-Eclipses.The word Eclipse is derived from the Greek word 'elkeipses', meaning forsaking or disappearance.

The eclipses are of two Types-
1) Solar Eclipses
2) Lunar Eclipses

There may be a maximum of seven eclipses in a calender year and sometimes it may be as few as two.In the year in which there are seven eclipses, five of these may be of the Sun and two of the Moon.When there are only two eclipses, both of these must be of the Sun.

A Solar Eclipse occurs when the Moon passes between the Sun and the Earth,blocking the Sun's light from reaching the Earth's Surface.

A Lunar Eclipse occurs when the Earth comes in between the Sun and the Moon, which means that the Sun,Moon and the Earth lie along a straight line.The sunlight falling on the Moon gets cut off as the Moon's straight going behind the Earth and the Earth's shadow falls on the Moon, thus eclipsing it.
