How often does a solar eclipse occur?
Although solar eclipses seem extremely rare – because they are not often visible from the same spot on the planet – they actually occur quite frequently. Every year, there can be between 2 and 5 solar eclipses across the globe. That said, not all of them are total eclipses: some are partial or annular, and sometimes the total eclipse is only visible from a very narrow strip.
The most common scenario is two solar eclipses per year. Three or four are less frequent, and five solar eclipses in a single year is a very rare event that occurs only a few times per century.
However, as the Moon’s shadow is very small, the probability of the eclipse passing over exactly the same spot is very low. For this reason, at any given fixed location on Earth, a total eclipse occurs only once every 300 to 400 years, or less.
