It’s a rare sight
A solar eclipse happens when the moon comes between the Earth and the sun, blocking out the sun and casting a shadow over the Earth. Partial eclipses happen a few times a year around the world, but a total eclipse—where the full sun is blocked out—only happens once every few decades in North America. That’s because the Earth is always spinning and moon is always orbiting and the two motions need to line up just right for the spectacle to occur. The full thing lasts two or three hours, though the sun is only fully covered for a couple of minutes.
