On the evening of November 4th and 5th, if the weather is fine, the Chinese public will enjoy the beautiful Venus accompanying the moon.

Recently, many attentive members of the public will find a star shining brightly in the low sky in the southwest when they look up on their way to get off work or school. This diamond-like star is "the brightest star in the night sky" - Venus.

In ancient my country, Venus was called "Taibai". When it is located to the west of the sun, it will appear in the faint morning light in the east in the morning, and is called the "morning star" or "morning star"; When the sun is in the east, it will appear in the sunset in the west in the evening and is called the "Chang Geng Star" or "Evening Star".

Due to its extremely high brightness, Venus can easily enter the public's sight. Therefore, "she" has a high exposure rate in various myths and legends at home and abroad, and is an out-and-out "traffic star".

Yang Jing, a member of the Chinese Astronomical Society and director of the Tianjin Astronomical Society, said that relative to the earth, Venus is an inner planet. Viewed from the earth, it only moves near the sun. We can usually only see it during a period of time in the early morning and evening. arrive. The moon is a satellite of the earth, and it moves around in the sky every other lunar month. Therefore, every time the moon passes near Venus, the moon phase is either the crescent moon at the beginning of the lunar month, or the waning moon at the end of the lunar month, and The distance and positional relationship between the two when they are together will also be different.

Recently, Venus has returned to the evening sky. As time goes by, its horizon height has gradually increased, and its observable time has become longer and longer. This also means that the moon passes by every month. When Venus is nearby, it can form a picture of "Venus with moth eyebrows". This month is no exception. The evenings on the 4th and 5th are a good time to appreciate Venus accompanying the moon.

Specifically, the 4th is the fourth day of the lunar calendar. After sunset, the moon is located on the lower right of Venus, and the distance between the two is slightly far. The 5th is the fifth day of the lunar calendar. In the evening, the moon is located to the left of Venus. The distance between the two is closer and easier to observe. For most parts of our country, this "fairy tale of stars and moon" can last about an hour. There is plenty of observation time. In the night, the moonlight is bright and the stars are bright, accompanying each other and pleasing to the eye.

"When interested members of the public observe this 'Star and Moon Fairytale', they do not need to use a telescope, just the naked eye; when choosing a location, try to choose an unobstructed location in the southwest." Yang Jing reminded.
