The exact diameter of the Sun was calculated by Japanese astronomers

Scientists from Japan reported in April 2013 that they were able to calculate the exact diameter of the Sun. In North America and parts of Asia, a ring-shaped eclipse was observed at that time. For the calculations, the effect of "Bailey's beads" was used. The effect is formed in the initial and in the final phase of the eclipse.

At this time, the edges of the disks of the two luminaries - the Sun and the Moon, coincide. But the relief of the Moon has many unevennesses, therefore through them the sunlight passes in the form of bright red dots. According to a special system, astronomers calculate the data and determine the circumference of the solar disk.

Comparison of the data obtained during the eclipse in various observatories in Japan, as well as the available calculations and observations, including those obtained from the Japanese lunar probe, made it possible to calculate the most accurate diameter of the Sun at the present time. According to their data, it is equal to 1 million 392 thousand 20 kilometers.

For many years all astronomers of the world have solved this problem. But too bright a luminary made it impossible to measure its diameter, so the Sun star has not yet been measured. Observing tumultuous changes, studying solar phenomena, scientists nevertheless moved forward in the study of this bright and very important star for us.

At its core, the sun is a ball consisting of a gas mixture. This is the main source of energy of the Sun, which sends us light and warmth. They travel a distance of one and a half hundred million kilometers until some part of them reaches Earth. If all his energy overcame atmospheric resistance, then in one minute two grams of water would raise the temperature by one degree. In former times this value was taken as a constant solar number, but later fluctuations in solar activity were revealed , and geophysical scientists began to monitor the temperature of the water in special tubes installed under direct sunlight. By multiplying this value by the radius of the distance, the value of its radiation is obtained.

So far, the diameter of the Sun has been calculated using the distance from the Earth to the star and the apparent angular value of its diameter. Thus, an approximate number of 1 million 390 thousand 600 kilometers was obtained. Then the scientists divided the calculated radiation value by the surface value and, as a result, received a luminescence force per square meter. centimeter.

So it was found out that the strength of its glow exceeds the glow of molten platinum by a factor of tens. Now imagine that the Earth receives only a very, very small part of this energy. But nature is arranged in such a way that this energy on earth increases.

For example, the sun's rays warm the air. As a result of the difference in temperature, it begins to move, creating a wind that also gives energy, rotates the turbine blades. The other part heats the water, which feeds the earth, yet another part is absorbed by the plant and animal world. A little bit of the sun's heat goes to the formation of coal and peat, oil. After all, natural chemical reactions also need a source of heat.

The energy of this star is very important for earthlings, so the success of scientists from Japan, who managed to get a more accurate diameter of the Sun, are considered a very important discovery.
