On the 26th of this month, Tianyu will stage a spectacular solar eclipse. Astronomical experts said that during this annular eclipse, partial solar eclipse can be observed all over China, and the farther south the eclipse (the ratio of the moon covering the diameter of the sun) is, the greater it is. A solar eclipse occurs when the sun, the moon and the earth are in a straight line and the moon is between them. Eclipses are divided into total solar eclipse, annular solar eclipse and partial solar eclipse. If the distance to the moon is far from the earth, and the sun is close to the earth, and the apparent circle of the moon is too small to completely cover the sun, an annular eclipse will occur. When the annular eclipse occurred, the sun in the sky turned into a ring, shining like a' golden ring'.

The eclipse belt starts from the Middle East, passes through the southern tip of India and Sri Lanka, enters Indonesia, Singapore, Malaysia and other countries in Southeast Asia, and finally ends in the Western Pacific. The average width of this annular eclipse belt is about 1 15 km, and the longest time to see the annular eclipse is about 3 minutes and 40 seconds.

At about 10: 56, the penumbra of the moon entered the Ali region of Tibet in China, and then the penumbra of the moon swept across China in the northeast. Different degrees of partial solar eclipse can be seen in China, among which Hainan has the largest food score of 0.499; Mohe has the smallest food score, which is 0.02 1. After 15: 37, the penumbra of the moon left China from Hainan Province. For China, it can be seen that the eclipse lasted for more than four hours. " Shi Zhicheng said. Astronomical experts said that although it is not as spectacular as the total solar eclipse and the annular solar eclipse, the partial solar eclipse is also wonderful.
