Given there has not been a total solar eclipse in the continental U.S. On August 21, the continental United States will host one of the most spectacular total solar eclipse events to have occurred since the arrival of Europeans to its shores. Red colors above denote annular eclipse paths. This results in an annular eclipse, where a "ring of fire" (annulus) is seen around the edge of the moon. However, because of small orbital variations, the moon does not always fully obscure the sun during some eclipses. The sun and moon are almost exactly the same size when viewed from Earth, which is why we get total eclipses. Blue paths above show where the sun will be completely blocked for each total eclipse, including the one that will pass across the United States on August 21, 2017.
