The moon, is the moon we see with the naked eye, known as XuanTu, Chan Juan, etc. in ancient times, was born 4.5 billion years ago, adjacent to the earth in the solar system, is the brightest celestial body in addition to the sun, rotating and rotating around the earth, in many myths, the ancients recorded the moon is particularly extensive, such as the Moon in the Guanghan Palace living Chang'e and Jade Rabbit have been passed down to this day, but also concluded that the time flow between the underground and the sky is not the same, there is a "day in the sky, a year underground", is that really the case?
If a person spends a day on the moon, how long is earth?
Whenever night falls, when we see the front of the moon, it appears as a patch of gray flakes of different sizes, which are huge impact craters filled by basalt lava flows from volcanoes, called "moon seas". In the entire solar system, each planet is in an orderly orbit, and the distance from the sun is different, so the time of operation is also the same, we all know that the earth rotates around the sun, under the earth's gravity, the moon orbits the earth's trajectory direction, the time is also very different, the earth is also affected by the moon.
The earth rotates around the sun a cycle is 24 hours, that is, the usual day, the earth's rotation is 365 days, that is, a year, but the rotation of the moon and the earth and the rotation is synchronized, the moon's cycle is 27.32 days, that is, the rotation of a week will take about 648 hours, from the time calculation point of view, in fact, the moon day, the earth has passed almost a month, the speed of operation is slow, but the date is much faster than the earth.
Doesn't it sound amazing, scientists say it is like this, the moon is not as clear as the earth's four seasons, when the moon rotates, only when we see it at night, there is always only one side to us, so when we turn a circle, the other side of the moon is blocked by the sun, then the moon still does not stop rotating, until the end of a cycle, the moon's rotation and rotation are the same.
Nowadays, the development of the aerospace industry is booming, as early as that year, there was manned spaceflight put on the moon, the mainland's "Chang'e" series also launched the moon successfully, let us deepen the new understanding of the moon, for the overall knowledge of the moon, the operation of the law have a great explanation, the ancients on its record description, said that the technology at that time was not developed, but there is also a place in line with the reference.
