lunar is rising

The moon on the twenty-second day of the lunar calendar was the last quarter of the moon. It usually rose around midnight and set around noon. For example, on Tuesday, October 22, the moon near its last quarter on September 20 of the lunar calendar rises at 21 or 22 o'clock. However, the exact time of the moon's rise may vary according to geographical location, season, and other factors. The novel New Moon is equally exciting. Everyone is welcome to click and read it!

In the Lunar New Year game, the "new moon" must be on the first day of each month in the lunar calendar. The "moon" was usually 14 days, 18 hours, and 22 minutes after the "new moon." The exact date of the start and progress of the game was determined by the lunar calendar. As long as the game could be launched between the first day of each lunar month (New Moon) and about 14 days, 18 hours and 22 minutes (Hope), there was no fixed Gregorian calendar date to correspond with.

The moon's orbit around the earth was about 27.32 days (stellar month), which was the time it took for the moon to orbit around the earth in an oval orbit. The lunar phase change period was about 29.53 days (the lunar month). The lunar phase change was caused by the lunar orbit around the Earth and the relative position between the Earth, the Moon, and the Sun. The moonlight that we could see was the sunlight reflected by the Moon. Because the reflection angle changed with the relative position of the Earth, the Moon, and the Sun, we could see different lunar phases. From the new moon to the full moon and then to the new moon, we completed a lunar cycle. The novel New Moon is equally exciting. Everyone is welcome to click and read it!

There were many scenarios for the lunar debris. On the one hand, there were debris on the surface of the moon caused by asteroid impacts. For example, research speculated that 2016 HO3 (also known as 469219 Kamo'oalewa,"Shocking Star") might be the debris of the moon after being hit by an asteroid. The researchers determined its composition through spectral analysis and found that it was similar to the samples brought back by Apollo. According to its rotation speed, structure, and other characteristics, they speculated that it was blasted out of the moon as a whole. The crater produced by the impact should be more than 10 - 20 kilometers in diameter. The formation of the crater may have been 100 million to 10 million years ago, of which the Giordano Bruno crater was the most likely. At that time, an asteroid with a diameter of 1.66 kilometers hit the moon. As many as 400 fragments about the size of Kamo'oalewa were produced. On the other hand, there were also debris left behind by humans exploring the moon, totaling at least 200 tons. The sources included items abandoned by astronauts and spacecraft, such as domestic garbage, instrument debris, and even astronauts 'excrement. There were also debris formed by some probes crashing on the surface of the moon after completing their missions. In addition, the formation of the moon also involved the concept of debris. The most widely accepted Theia hypothesis believed that about 4.5 billion years ago, the planet Theia (about the size of Mars) crashed into Earth. A large number of debris was blown into space and formed the moon under the influence of gravity. Moreover, recent research found that there were two spots as large as the moon inside the Earth, which may be the debris of the planet Theia that formed the moon.
