In 2013 and 2014 there will be a total of four solar eclipses. When the moon casts a shadow over the Earth, and the moon is between the sun and Earth, there is a solar eclipse.
On earth there are 2 eclipses, Lunar and Solar eclipses
There are generally two solar eclipses and two lunar eclipses each year. Because solar eclipses cover a very narrow stripe across the Earth, solar eclipses SEEM TO BE rare - in one particular location. There can be several CENTURIES between total solar eclipses in the same spot. On the other hand, it can be just a few years. There's a town in Illinois that will have two total solar eclipses only 8 years apart, in 2017 and 2024.
There are between 2 and 5 solar eclipses each year. In 2011, there are four solar eclipses, all partial ones. There is also one every ten years
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.
solar and lunar.
Over the average of many years, there are 2.3 of each kind of eclipse per year, both solar and lunar. During the 20th Century (1901 to 2000) there 229 solar and 230 lunar eclipses.
There are typically between 2 to 7 eclipses each year, which can be a combination of solar and lunar eclipses. Solar eclipses occur when the Moon passes between the Earth and the Sun, while lunar eclipses happen when the Earth passes between the Sun and the Moon.
Both solar and lunar eclipses generally occur 2 times a year. Some years you will have fewer, or more. For example, there will be NO solar eclipses at all during 2011! The maximum possible number of solar or lunar eclipses per year is five.
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.
There are generally, on average, two solar eclipses per year. Sometimes there are fewer. In 2011, there will be 4 partial solar eclipses (and two total lunar ones. Sometimes there are more; the maximum possible would be five. But on average, two per year. Of these solar eclipses, about 25% are total and 25% are annular, with the remainder being partial. Lunar eclipses also occur, on average, twice a year. Roughly half are total; the remainder are partial or penumbral. 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's no regular schedule. Here are a few facts: -- The closest together that two eclipses can possibly be is about 2 weeks. -- On the average over a period of many years, there are about 2.3 lunar eclipses and 2.3 solar ones every year. But that's a long-term average. -- There can be anywhere from one to five eclipses in one year ... lunar, solar, or mixed.
The long-term average period of the complete cycle of moon phases is 29.531 days. So whatever shape of the moon you're looking at, you'll see the same phase again in that length of time later.
