If only people along the narrow path of totality will see the total eclipse, millions more will see some degree of a partial solar eclipse in Asia and the Pacific, including Hawaii, Guam and parts of Alaska.
A partial eclipse will also be visible along the path of totality for more than one hour before and after the total eclipse.
As the moon passes exactly between the Sun and Earth a relatively rare occurrence that happens only once a year because of the fact that the moon and the sun does not orbit in the same exact plan that will block the bright face of the sun, showing comparatively thin and weak solar atmosphere, the corona.
The phenomenon will last for one and a half to just over four minutes each.
Although more than three hours pass between the time the westernmost place will see the eclipse as the easternmost location sees the end of the eclipse, according to NASA.
