Earth moves a round the sun and the moon moves around the earth.

Sometimes the sun, the earth and the moon are in straight line

When this situation happen, we will experience the eclipse of sun (solar eclipse) and eclipse of moon (lunar eclipse)

A lunar eclipse occurs when the Earth's shadow falls on the moon. Lunar eclipses occur, on average, about every 6 months

Total Eclipse - When the entire moon enters the Earth's umbra (the darkest part of its shadow), this is called a total eclipse.

Partial Eclipse - When only part of the moon enters the Earth's umbra, this is called a partial eclipse.

Occurs when the moon lies between the sun and the earth.
