There are, on average, two solar eclipses and two lunar eclipses each year. In 1999, there was an annular solar eclipse on February 16, and a total solar eclipse on August 11.
For lunar eclipses, there was a penumbral lunar eclipse on January 21 and a partial lunar eclipse on July 16.
You can look up all eclipses from 2000 BC to 3000 AD on the NASA Eclipse web page.
On average, we can expect two lunar eclipses and two solar eclipses in any year. 2010 will have four eclipses, right on the average.
The answer very much depends on the year. One calendar year has a minimum of four eclipses, which are two solar eclipses and two lunar eclipses. A year can have as many as seven eclipses. So each year is different.
Total lunar eclipses occur between 0-3 times per year.
there are at least two lunar eclipses in a year
About one or two solar eclipses per year, and one or two lunar (Moon) eclipses per year, on average. Go to NASA.com and search it. there will be a map with the spots of eclipses and time/year.
If you're referring to complete lunar eclipses (a lunar eclipse when the moon is full) then unlikely....but any other lunar eclipse (any other moon phase) usually happens atleast twice a year.
none to 3 lunar eclipses a year
Five is the theoretical maximum number of solar eclipses in one calendar year; generally 4 partial eclipses and one total or annular eclipse. This configuration happens about every 200 years or so. Interestingly, there will be four solar eclipses in 2011; all will be partial eclipses, visible (if at all) only from polar regions. The last time there were five solar eclipses in a year was in 1935; the next time will be in 2206.
The total number of eclipses each year does not exceed seven: typically, there are a maximum of five solar eclipses and two lunar eclipses in a given year. This number can vary slightly due to particular celestial alignments.
Total solar eclipses are rare events. Although they occur somewhere on Earth every 18 months on average, it has been estimated that they recur at any given planly once every 370 years, on average.
It varies. During the 100 years of the 20th Century (1901 - 2000), there were 228 solar eclipses and 229 lunar ones, for an average of about 2.3 per year. Any one year may have 2 - 5 of each.
During the 100-year period from 1901 to 2000, there were 228 solar eclipses and 229 lunar eclipses. On the average, that's 2.28 or 2.29 of each kind, for every year, but in in individual year, it can be as many as 4.
