An annular eclipse occurs when the Sun and Moon are exactly in line, but the apparent size of the Moon is smaller than that of the Sun. This is because the distance of the moon from earth varies. The Sun appears as a very bright ring, or annulus, surrounding the outline of the Moon.
No, annular eclipses do not happen every year. They occur when the Moon is farthest from Earth, making it appear smaller and not fully cover the Sun during the eclipse. This alignment is not a regular occurrence, so annular eclipses happen less frequently than total solar eclipses.

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.
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.
Partial 35.3%Annular 33.2%Total 26.7%Hybrid 4.8% As you can see from the table above, partial eclipses are most common, followed by annular eclipses. Total solar eclipses are barely more than one-quarter of the total. Total eclipses occur when the Moon is close enough to the Earth for the umbra, the cone of total shadow, to hit the Earth. Annular eclipses occur when the Moon is so far away that the umbra does not reach all the way to the Earth. "Hybrid" eclipses occur when the Moon crosses the dividing line between total and annular DURING the eclipse, so that the eclipse begins as annular and changes to total, or vice versa, during the eclipse.

There are generally between two and five solar eclipses every year. Half or so will be partial or penumbral eclipses, and half of the rest will be annular, meaning that about one quarter of all solar eclipses are total. In 2011, there are four partial solar eclipses. The first was on January 4; the next will be on June 10.

There are generally two lunar eclipses and two solar eclipses each year. Sometimes you will see two partial eclipses instead of one total eclipse; in 2011, there will be four partial solar eclipses, and no total or annular solar eclipses. Since lunar eclipses happen on the Moon, they are visible from the entire night half of the Earth. Solar eclipses, when the Moon's shadow hits the Earth, affect very small areas of the Earth, and so they seem to be more rare. The next total lunar eclipse will happen on December 21, 2010, and will be visible from any point in North America.
A solar eclipse can only happen when the Moon passes between the Sun and Earth, blocking the Sun's light and casting a shadow on Earth. This alignment can create different types of solar eclipses, such as total, partial, or annular eclipses, depending on the positions of the Sun, Moon, and Earth.
Solar eclipses can only occur at the new moon, while all lunar eclipses happen at the full moon.
Solar eclipses are caused by the shadow of the Moon hitting the Earth. Solar eclipses happen on the Earth.
No, solar eclipses can be years apart.
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.
