Why the Eclipse Velocity ​​Varies

The velocity at which the moon’s shadow strikes in the course of the eclipse will differ based mostly in your geographical location. The shadow is just not uniform and can shift because it crosses totally different components of the Earth. The curvature of the earthmixed with the altering distance between the moon and the bottom beneath, impacts how rapidly the shadow travels throughout the floor.

The place the Shadow Will Transfer the Quickest

In some areas, significantly when the eclipse is simply starting or ending, the shadow of the moon will race at unbelievable speeds. At these excessive factors, the moon’s shadow will exceed 10 million km/h. This speedy motion occurs when the shadow hits the Earth at a pointy angle, inflicting the eclipse to flash throughout the sky in simply moments.

The place the Shadow Will Transfer the Slowest

At sure factors, significantly over the Pacific Ocean, the eclipse will decelerate dramatically. On this area, the shadow of the moon will crawl at speeds of roughly 2,057 km/h. That is the place the eclipse will final the longest, with the ring of fireplace remaining seen for a number of minutes, permitting observers to take pleasure in a protracted view of this distinctive occasion.

What Causes the Velocity ​​Fluctuations?

The differing speeds are as a result of a number of components. The eclipse begins when the shadow of the moon first makes contact with the Earth, which happens at a steep angle, inflicting the shadow to maneuver rapidly. Because the eclipse progresses, the shadow begins to strike the Earth extra immediately, slowing it down. The ultimate issue is the gap between the moon and the Earth, which consistently shifts and additional influences the velocity.
