The cause of Jupiter's accompanying moon
According to astronomical experts, the orbit of the moon around the earth is an ellipse, which moves fast when it is near and slow when it is far away. If it is the first half of the month, there will be a full moon on the fifteenth; If it is slow, it will reach the full moon position in the early morning of 16 or 17.
According to statistics, from 2002 to 2005, the Mid-Autumn Festival was on the 15th day of the eighth lunar month, but since 2006, the full moon of the Mid-Autumn Festival has been on the 16th for five consecutive years, and it is expected to return to the 15th next year. In addition, last night's Mid-Autumn Festival moon was a little smaller than before, which was caused by the moon just passing the apogee.
Astronomical experts said that the Mid-Autumn Moon was the farthest from the Earth since 1992, and it passed the apogee 16 on September 2 and reached 406 165 kilometers away from the Earth. Therefore, the apparent diameter of the Mid-Autumn Moon you saw this year is the smallest since 18 years, which is nearly 10% smaller than the usual full moon.
