How often is there a total eclipse of the sun?
Solar eclipses are fairly numerous, about 2 to 4 per year, but the area on the ground covered by totality is only about 50 miles wide. In any given location on Earth, a total eclipse happens only once every hundred years or so, though for selected locations they can occur as little as a few years apart.
How many times solar eclipse occur in a year?
Solar eclipses occur two to five times a year, five being exceptional; there last were five in 1935, and there will not be five again until 2206. The average number of total solar eclipses in a century is 66 for Earth as a whole.
When was the last total eclipse of the sun?
Aug. 21, 2017
A total solar eclipse — like the one that crossed the U.S. on Aug. 21, 2017 — occurs when the moon blocks 100% of the solar disk. If an observer is standing within the path of totality, they will notice a 360-degree sunset and see just the outermost layer of the sun, called the corona, during the total eclipse’s peak.

When was the last time there was a total solar eclipse?
For this eclipse, the longest period when the moon completely blocks the sun from any given location along the path will be about two minutes and 40 seconds. The last time the contiguous U.S. saw a total eclipse was in 1979. Figure 3 – Diagram showing the Earth-sun-moon geometry of a total solar eclipse.
How long does it take to see a total solar eclipse?
Only viewers located in the path of the Moon’s full shadow, its umbra, can see a total solar eclipse. The Moon’s umbra travels eastward at about 1,700 km/h (1,056 mph). A total solar eclipse can last for several hours. Totality can range from a few seconds to 7.5 minutes.
