Is the moon in Mid-Autumn Festival closest to the earth?
The moon revolves around the earth with an average radius of 384,400 kilometers. When the distance to the moon is closest to the earth, it is called perigee; The farthest time from the earth is called apogee. The lunar phase happens to be the "full moon", and when the revolution of the moon is in the "perigee" position, you will see the "super moon".
Wang Kechao, director of popular science at Purple Mountain Observatory, Chinese Academy of Sciences: On the night of Mid-Autumn Festival on September 29th, we will see a big round moon, which is the third closest moon to the earth this year and can be called "super moon". At this time, the distance between the earth and the moon is about 362,000 kilometers, and the most round moment of the moon is September 29th 17:58.
Moon characteristics of Mid-Autumn Festival:
You can see the roundest Mid-Autumn Moon in China and all over Asia. The full moon in the Mid-Autumn Festival appears at 2 1: 59 on the evening of August 15th of the lunar calendar. Mid-Autumn Moon is smaller, the highest since 1993. This is because during the Mid-Autumn Festival, the moon moved to the farthest position from the earth. In the early morning of the 17th day of the eighth lunar month, people see that the apparent diameter of the moon is the smallest.
The moon rises late, the latest since 1995. In Guangzhou, the Mid-Autumn Festival in jathyapple this year is 18: 32, 44 minutes later than last year. The height angle of the moon's horizon in Mid-Autumn Festival is obviously lower than normal. This will bring an interesting and rare astronomical phenomenon to people living in Beijing, that is, when the moon is brightest in the Mid-Autumn Festival (mid-day), the moon is not high or low, but just rises into the air; The moon is neither east nor west, becoming a veritable "compass".
