Correctly determine the diameter of the Sun.

The exact diameter of the Sun is 1,392,020km. That is the result of research by scientists of the Japan National Observatory, according to information of Russian news agency ITAR-TASS.

The exact diameter of the Sun is determined to be 1,392,020km.

During the observation of the astronomical phenomenon that has just happened, most people in Asia and North America witnessed, Japanese scientists have calculated the exact diameter of the Sun, thanks to the optical effect of the present. The statue is called 'Bailey's Pearl Chain' (rosary Bailey) - a phenomenon of a series of bright spots appearing after the Sun disc was completely obscured by the Moon, described by British astronomer Francis Bailey in 1836.

This 'string of pearls ' is observed at the beginning and end of the total eclipse. At this very moment, the edges of the Sun and Moon disks overlap, but sunlight still penetrates through many places because the Moon's terrain is uneven and if seen from the Earth will see red highlights.

Thanks to the "Bailey pearl chain" , astronomers determine the location of the Sun's disk and thereby calculate the exact diameter of the Sun.

World astronomers for many years tried to determine the exact diameter of this star but were not able to do it because the task was complicated because the Sun disk had a very high glare, preventing major identification. locate it.
