A lunar eclipse occurs when the moon passes through the Earth's shadow - this can only happen during the Full Moon phase.
On earth there are 2 eclipses, Lunar and Solar eclipses
An eclipse of the moon happens when the shadow of the earth falls across the moon. This happens on a recurring basis and thus your question is meaningless - as eclipses of the moon have happened in the far past and will continue to happen into the fare future - counting them is impossible!
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.
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.
