A total solar eclipse is a rare event. Although they occur somewhere on Earth every 18 months on average, it is estimated that they recur at any given place once every 370 years. Why are reoccurring solar eclipses so rare?

• The light from the sun usually passes through the moon instead of being blocked by it.
• A total solar eclipse actually occurs monthly, but is only visible from the equater
• The Moon passes slightly above or below the line between the Sun and Earth because of its tilted orbit
