The most wonderful introduction of Venus in the whole year.
On February 17, Venus in the form of "Chang Geng Xing" will be the brightest in the whole year. In the southwest sky, it will shine like a gem and be as bright as a lighthouse.
Whenever Venus is far from the east (a good time to watch Venus at dusk) or far from the west (a good time to watch Venus in the morning), its angular distance from the sun is the largest, which is more conducive to observation. However, distance is not the brightest time for Venus, because Venus is still far from the earth at this time. After a distance to the east, Venus gradually approaches the earth, and its brightness increases. However, due to the phase change of Venus, the part of the sun shining on the earth is getting smaller and smaller, so there is a moment when Venus reaches its brightest. After this moment, the brightness of Venus began to decline. Similarly, at some point before the great distance to the west, the brightness of Venus reached its brightest again.
Jassamyn Liu, secretary-general of Tianjin Astronomical Society, said that on June+10/October 12, 65438, Venus headed east. Since then, Venus has become brighter and brighter. February 17 reached the brightest in the whole year, which was -4.8 or even brighter. Shadows of houses, trees, animals and people can be reflected in the dark and observed even in the daytime.
