Astra’s Guide to the Total Solar Eclipse

August 21, 2017

Total Solar Eclipse across the USA!

Coast-to-Coast the August 21, 2017 solar eclipse will thrill observers across the United States of America!

What makes a total solar eclipse? A total solar eclipse occurs when the moon comes directly between the Earth and the Sun as viewed from a specific location on the surface. What makes this possible is the fact that the disk of the Moon and the Sun appear a similar size to an Earth observer. Because the Moon's orbit is offset from the Sun by 5 degrees this phenomena is only observable when both are at a node.
