Top 10 Lunar Eclipse Facts By Robert Roy Britt Senior Science Writer posted: 07:00 am ET 13 May 2003

3) Lunar eclipses are frequent, relatively speaking
Though you might not have logged many lunar eclipses in your life, they are
common compared to solar eclipses, at least in one sense.
Solar eclipses are fairly numerous, generally two to five per year, but the
area on the ground covered by totality is only a few tens of miles (kilometers)
wide, so it's rare to be in the path of a total solar eclipse. In any given
location on Earth, a total solar eclipse happens only once every 360 years.
Lunar eclipses are less frequent, but total lunar eclipses are visible everywhere
that it is nighttime as the event takes place -- essentially half the globe.
Any given location can experience up to three lunar eclipses per year. Some
years there are none.
