What happens more often, solar or lunar eclipses?
According to Fred Whipple’s book Earth, Moon and Planets, solar eclipses are fairly numerous, about two to five per year, but the area on the ground covered by totality is only a few miles (kilometers) wide. In any given location on Earth, a total eclipse happens only once every 360 years. Eclipses of the Moon created by Earth’s shadow are actually less numerous than solar eclipses; however, each lunar eclipse covers about half of Earth’s surface. 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.
