Xinhua News Agency, Tianjin, February 10 (Reporter Zhou Runjian) After Venus, who appeared in the "Chang Gung" attitude on December 4, 2021, ushered in the brightest of the year, on February 13, 2022, the star appeared in the "Qi Ming" attitude. Venus will once again be at its brightest of the year, and if the weather is fine, interested members of the public can get up early and face the southeast sky to see how it opens the dawn.
Venus is the nearest neighbor of the earth. In ancient my country, it was called "Taibai", that is, Taibaixing.
When it appears in the morning, people call it "Qi Ming" or "Morning Star"; when it appears in the evening, people call it "Chang Geng" or "Evening Star".
Under normal circumstances, Venus is the brightest celestial body in the whole sky except the sun and moon, and it can reach a magnitude of -4.9 at its maximum brightness.
Xiu Lipeng, director of the Tianjin Astronomical Society and an astronomical science expert, said that Venus meets the earth once every 584 days. During this period, Venus will be the brightest twice, and the interval between the two brightest is very short. One time is on Venus. After the great east distance, once before the great west distance of Venus.
On October 30, 2021, Venus ushered in the great east distance.
Since then, Venus has become brighter and brighter. On December 4, Venus, which appeared in the "Chang Gung" attitude, ushered in the brightest of the year, with a brightness of -4.9 magnitude; on March 20, 2022, Venus will usher in a large western distance.
In the 36 days before that, that is, on February 13, Venus, which appeared in the "enlightenment" attitude, will once again usher in the brightest of the year, with a brightness of -4.9 magnitude.
Xiu Lipeng said that the brightest Venus must occur when Venus is in a "crescent moon" state before and after the lower conjunction, not when it is in a "full moon" state before and after the upper conjunction.
"Conjunction is when Venus and the sun appear to be in the same direction in the sky from the Earth. In the upper conjunction, the Earth and Venus are on opposite sides of the sun, and the distance between the two is at the furthest; in the lower conjunction, the Earth and Venus are on the same side. , at this time the two are the closest." Xiu Lipeng explained.
In January 2022, Venus moved to the west of the sun, becoming a morning star, rising out of the ground earlier than the sun.
"At dawn on the 13th, if the weather is fine, and interested members of the public look to the southeast sky, with the naked eye, they can see the diamond-like Venus set in the sky, dazzling. Of course, viewing Venus is not limited to the 13th. On this day, before and after this time, its 'shining figure' can be seen in the morning light before dawn." Xiu Lipeng said.
