Are there more solar or lunar eclipses each year?
Total solar eclipses can be expected about every year and a half or so, but in any one calendar year, there are at least two and as many as five solar eclipses … these can be partial, total and annular and often only visible from isolated regions of the Earth, which is why they seem so infrequent. In fact, solar eclipses outnumber lunar eclipses by almost 5 to 3, if you ignore the penumbral lunar eclipses that are essentially unobservable. Total lunar eclipses come in clusters. There can be two or three during a period of a year or a year and a half, followed by a lull of two or three years before another round begins. When you add partial eclipses there can be three in a calendar year and again, it’s quite possible to have none at all. Lunar eclipses are visible from the entire nighttime hemisphere of our planet and as a result are more frequently observed and seem to be more numerous. Source:
