Total Solar Eclipse
A solar eclipse happen when the moon passes between the Sun and the Earth so that the Sun is fully or partially covered. This can only occur during a new moon, when the Sun and Moon are in conjunction as seen from the Earth.Commonly About two to five solar eclipses can occur each year on Earth.but out of this zero to two are total solar eclipse. An eclipse of the Sun (or solar eclipse) can only occur at New Moon when the Moon passes between Earth and Sun. If the Moon's shadow happens to fall upon Earth's surface at that time, we see some portion of the Sun's disk covered or 'eclipsed' by the Moon.
Duration
7 min 30 sec is the maximum duration for an solar eclipse on a specific place.
But mostly ,we can't reach up to this time,and ends within 6 minutes.
There are four types of solar eclipse, they are:
Total solar eclipse
When the Sun is completely obscured by the Moon
Annular eclipse
when the Sun and Moon are exactly in line, but the apparent size of the Moon is smaller than that of the Sun.
Hybrid eclipse
It is an transitions between a total and annular eclipse. At some points on the surface of the Earth it is visible as a total eclipse, whereas at others it is annular.It is the rarest eclipse .The last hybrid eclipse was in 2005 and the next one is in 2013.
Partial eclipse
When the Sun and Moon are not exactly in line and the Moon only partially obscures the Sun.
