"October's Annular Solar Eclipse: Travel Speed, Safety, Viewing Locations, FAQs, and Impact on Texas Power Grid"
Originally Published 2 years ago — by Space.com

The speed of October's annular solar eclipse will vary depending on the location on Earth. The moon's shadow will travel as fast as 7,000 mph and as slow as 1,700 mph. The speed is influenced by the geometry of the Earth, the distance to the moon, and the moon's orbital speed. The eclipse will move fastest at the extremes of its path and slowest in the middle. In the U.S., the shadow's speed will decrease from 5,683 mph to 1,772 mph as it passes through. The eclipse will create a "ring of fire" as the moon's antumbral shadow passes across the Earth's surface.
