2.5 minutes of dakness during the day when the moon covers the sun
It will be phenomenal. I will drive to Buffalo to watch it.
Somewhere on Earth, there is a total solar eclipse about once every 18 months through a strange scientific fluke. By chance, the moon, at an average distance of about 386,000 kilometres from Earth, just happens to be the same size in the sky as the sun, which is at an average distance of 149.6 million kilometres.
Every so often, it all lines up and, as the moon orbits Earth, it passes in front of the sun, blocking it out entirely.
