China News Service, Guangzhou, December 2 (Guo Jun and Li Jianji) According to the prediction of the Wuyang Planetarium in Guangzhou: On December 4 this year, Venus (Chang Gung Star) will be the brightest with a brightness of minus 4.9 stars, the highest in 8 years.

After night fell, Venus radiated a dazzling and charming light in the low-altitude south of the west, dazzling the stars.

As long as the sky is clear, you can see it all over China.

　　Venus is the inner planet of the Earth. It is the closest to the Earth and has a radius of 300 kilometers smaller than that of the Earth.

The earliest collection of poems in my country, "The Book of Songs", says: "East has Qiming, and west has Chang Gung."

In ancient my country, when Venus rose in the east before dawn, it was called "Venus"; when Venus appeared in the west sky after sunset, it was called "Chang Gung Star."

The West calls Venus the "Goddess of Venus".

In the recent evening, the Chang Gung star (Venus) witnessed by the public from all over my country in the southwest was the brightest since December 7, 2013.

　　Why does the brightness of Venus show its highest brightness in 8 years?

Mainly in recent days, the earth is not only closer to the sun (on January 4 next year, the earth passes perihelion), but also closer to Venus.

The combination of the two has become the highest brightness in the past 8 years.

On October 30 this year, Venus will be at a distance of 0.49 to the east, which means that the sun's rays illuminate 49% of Venus's apparent area.

On December 4, Venus will be the brightest with an aspect of 0.26.

　　Experts suggest that when watching the brightest Venus, don't forget to watch the rare sights of "three-star line (Venus, Saturn, and Jupiter three stars)".

From now to December 18, if the weather is clear, China and even the rest of the world (except the Arctic and Antarctic) will be able to watch this wonder during the period of 30 to 60 minutes at sunset.

On December 4th, the sunset time in Guangzhou was 17:41, that is, between 18:11 and 41 in Guangzhou, the viewing effect was the best.
