A total solar eclipse in a specific location on Earth is rare and can happen approximately once every few centuries, although globally, total eclipses occur about every 18 months.
The frequency of a total solar eclipse in a particular location on Earth is relatively rare because each eclipse is visible only along a narrow path called the eclipse path. Due to the Moon's shadow moving at approximately 1500 kilometers per hour across Earth's surface, the duration of totality at any given point is brief, often lasting just a few minutes and never exceeding about 7 minutes.
The exact interval between total solar eclipses at a single location can vary significantly, but on average, it might be several centuries. However, across the globe, total solar eclipses occur approximately every 18 months. The recent 2017 total solar eclipse traversed the United States and was a significant event for eclipse chasers and enthusiasts.
