This year’s Mid-Autumn Festival "15 Moon and 15-round"


   forecast shows that the weather in Beijing tomorrow will be fine and citizens can watch a full moon on the Mid-Autumn Festival night.

  News from our newspaper (reporter Lei Jia) Tomorrow will be the Chinese traditional Mid-Autumn Festival.

Unlike the “16-round moon at 15” in most previous years, the moon for Mid-Autumn Festival this year is August 15th. Although the fullest hour appears on the morning of the 15th, the weather forecast shows that Beijing’s weather tomorrow will be fine. See a full moon.

  According to Cowen, the chief science expert of the Beijing Planetarium, because the moon orbits the earth in an elliptical orbit, sometimes it is closer to the earth and sometimes farther away. When it is close to the earth, it moves faster, and when it is far away. , The speed is slower; therefore, the time from the new moon to the full moon is not completely fixed. Most of the full moon appears on the fifteenth and sixteenth, and in some cases it can appear on the seventeenth or even the fourteenth.

The full moon is sixteen the most, accounting for nearly 60%; the fifteenth is the next, accounting for about 40%, so there is the saying that "the moon is 16 round in fifteen".

  Tomorrow's full moon will be at 8 o'clock in the morning. At this time, the moon has fallen below the horizon in most parts of our country. In the morning, you can see the roundest moon at low altitude in the west.

Although the moon has passed its roundest moment on the night of this year’s Mid-Autumn Festival, it has only been more than ten hours later. It is difficult for human eyes to tell whether the moon is the roundest or not. Therefore, the 15th moon seen on the night of the Mid-Autumn Festival Still round.

  In addition, since the distance from the moon to the earth is far and near, the nearest is less than 360,000 kilometers, and the farthest is more than 400,000 kilometers. Therefore, the size of the moon also changes. Of course, this size change is difficult to see with the naked eye alone.

If the moon is exactly near the perigee at the full moon, it will look "big and round". This is the so-called "super moon."

This year's super moon will appear on May 26, and the smallest full moon will appear on December 19.

On the night of the Mid-Autumn Festival this year, the moon is about 390,000 kilometers away from the earth, which is slightly smaller than the average distance and below the average size.

The next super moon will appear on June 14 next year, May 16 of the lunar calendar.
