How often does a solar eclipse occur? How many times can you see it in your life?

How many years will it take for Bian Xiao to see the solar eclipse? How many times can you see it in your life? Eclipses occur at least twice a year. Because there is an included angle between the earth's orbit plane and the moon's orbit plane, there are two intersections. In this way, as long as the sun and the moon run to these two intersections, a solar eclipse will occur.

For the same place, it is no problem to ask how many years the solar eclipse occurs. For a certain place, the partial solar eclipse can only be seen once every three years, and the total solar eclipse can only be seen once every 300 years.

But for the whole world, there are not so few eclipses, at least twice a year and at most five times.

The occurrence of solar eclipse is not at equal intervals, but follows a cycle-Sharo cycle, with a length of 6585. During the interval of 32 days, that is, about 18 1 day for 8 hours, there were 7 1 eclipse, including 43 eclipses and 28 eclipses.

Because the positions of the earth, the moon and the sun return to the same relative position every once in a while, the same solar eclipse or lunar eclipse will occur, but because the positions of the three do not take into account the position of the earth's rotation, two solar eclipses with the same nature will not occur in the same place in such a time interval.

For example, a total solar eclipse occurred on July 199 1 day, and the eclipse belt passed through Latin America and the Pacific Ocean. People push forward 18 0 1 1 day,1June 30, 973. There must have been a solar eclipse. According to the data, it did happen. The food belt of the total solar eclipse crossed the African continent. If we push back a Sharo cycle, people can calculate that there will be a total solar eclipse on July 22nd, 2009, which is the total solar eclipse in the Yangtze River valley of China.

In this year, there are two solar eclipses on 20 16, which are the total solar eclipse on March 9 and the annular solar eclipse on September 1 day.
