How often do solar and lunar eclipses occur? |
Solar eclipses (including partial eclipses) occur more frequently than lunar eclipses; over the entire Earth there are two to five solar eclipses per year, while the average number of lunar eclipses per year is between one and two. A solar eclipse can only be observed by a narrow path on Earth’s surface while a lunar eclipse can be seen over a much larger area.
