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.
There are generally two solar eclipses per year, 6 months apart. However, one spot on the Earth will see eclipses only about every 60 years.
There are generally two solar eclipses and two lunar eclipses each year. Sometimes instead of having one total eclipse, we have two partial eclipses a month apart. The minimum number of eclipses in any year is one; the maximum possible would be five. We get the idea that lunar eclipses are more common than solar eclipses, but that's not true. It SEEMS that way, because solar eclipses (when the Moon's shadow hits the Earth) affect a very small path across the Earth's surface, and people outside this path don't generally notice the eclipse. But a lunar eclipse, when the Earth's shadow darkens the Moon, happens ON THE MOON, and is visible from the entire night half of the Earth. So many more people get to see a lunar eclipse, while only a few are in the path of a solar eclipse.
Tornadoes can happen in any season.
Annular eclipses are most common to happen in regions along the "path of annularity," which varies with each eclipse. These regions are typically located in the northern and southern hemispheres, often in remote or less populated areas. Japan is one of the countries where annular eclipses are relatively common.
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.
Most years, there are two solar eclipses. Some years, because of the precise geometry between the Sun, Earth and Moon, we have two partial eclipses instead of one total or annular eclipse. Very rarely, there are FOUR solar eclipses in one calendar year.Because each eclipse affects only a tiny area of the Earth, it is fairly rare for one location to experience two total solar eclipses in the same decade, and it isn't uncommon for there to be centuries between total solar eclipses for any specific spot on the Earth.
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.
No.
There are different numbers of lunar eclipses in different years. I think five (5) is the maximum possible in one 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.
