What happens more often, solar or lunar eclipses?
Solar eclipses are fairly numerous, about 2 to 4 per year, but the area on the ground covered by totality is only about 50 miles wide. In any given location on Earth, a total eclipse happens only once every hundred years or so, though for selected locations they can occur as little as a few years apart. An example is the August 21, 2017 and April 8, 2024 eclipses, which will be viewed at the same spot near Carbondale, Illinois. Eclipses of the Moon by the Earth's shadow are actually less numerous than solar eclipses; however, each lunar eclipse is visible from over half the Earth. At any given location, you can have up to three lunar eclipses per year, but some years there may be none. In any one calendar year, the maximum number of eclipses is four solar and three lunar.
