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.
there are at least two lunar eclipses in a year
Total lunar eclipses occur between 0-3 times per 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
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.
There are generally two solar eclipses and two lunar eclipses each year. Sometimes there are more, or fewer; for example, in 2011, there will be no solar eclipses at all. The maximum possible number is 5 per year, which happens very infrequently.
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.
Mercury and Venus can never have any eclipses, because they have no moons.
There are normally two solar eclipses each year. However, due to a curious alignment of the Earth, Moon and Sun, there will not be ANY solar eclipses in 2011!
