The world is soon to witness Surya Grahan or total solar eclipse on July 2, 2019. The eclipse is estimated to last for 4 minutes and 33 seconds, which is going to be longer than the 2 minutes and 40 seconds eclipse that took place in August 2017. The upcoming eclipse is going to be the only total solar eclipse that will occur this year.

It takes place when the sun, moon and earth are in a straight line in a way that the moon blocks the sun’s rays from reaching the earth.

About once every eighteen months, the moon and the sun collide, temporarily blocking the sun’s visibility. As the moon’s shadow makes its way across a part of the planet, places in the shadow’s path can experience anywhere between a few seconds and several minutes of twilight, depending on how close they are to the middle of the line of totality, or the route the moon’s shadow takes across the planet. There are two other kinds of solar eclipses — partial and annular eclipses — during which the moon does not block the sun entirely.
