The brightest thing in the night sky is the moon, which is still the brightest, and we have many beautiful myths and legends about the moon, but we know little about it. It is seen every day, but it always covers a mysterious veil。
First, there is no uniform statement of how the moon came into existence, and there are now four dominant hypotheses, one of which says that the moon was actually a child of the earth, originally integrated, for a reason that was removed from the earth and then began to rotate around it。
There is also a saying that the moon was also a small planet, captured by the earth as it ran over it and began to rotate around it。
The earth and the moon themselves are different planets, because the earth is of greater mass, slowly sucking it over and then starting to rotate around the earth。
Another story is that the impact said that a large meteorite hit the earth, and then the debris rotated around the earth and, over a long period of time, slowly condensed into the present moon。
At present, among the four hypotheses, the most recognized is impact, but so far no significant impact has been observed on the earth or on the moon, which is thought to be either a child of the earth or a fragment of the earth, because of the similar composition of the rocks on the moon。
The moon is our earth's satellite, but as a satellite, its head is absolutely enormous. It is the fifth largest satellite in the solar system, and the largest is io-san, with a diameter of 1 in 27 of jupiter, followed by titan in titan and 24 in saturn. The moon's diameter is one fourth of the earth's, and in proportion it's absolutely huge。
The fact that the moon will always have one side towards the earth and the other side will always have the same cycle of rotation and rotation, and that the moon will turn around the earth, without which there will always be only one face to the earth。
Because of the existence of the moon, a perfect eclipse can be formed, and its shadows can hold the sun perfectly, and it can be as big as the sun, because the diameter of the moon and the distance from the earth are the same as the diameter of the earth and the distance from the earth to the sun. Simply put, the relationship between the moon and the earth is the same as between the size and distance of the earth and the sun. The moon's size is so small that it's so close that it can't produce a perfect eclipse。
The moon is filled with large and small craters, the most incredible of which is that the depth of the craters on the moon is six kilometres. If a large meteorite strikes, it would logically produce deeper craters, the depth of the meteorite crater on earth and the size of the meteorite would be positive, with the entire moon as deep as six kilometres, with the largest crater on the moon having a diameter of 1,300 kilometres, and a calculus of 60 kilometres, if not less than 100 kilometres on earth。
The moon is like a very thick shell, no matter how big it is, it stops. Similar phenomena have been observed on jupiter's satellites, and research scientists have assumed that jupiter's satellites have ice shells on them, that meteorites would have thrown deep holes, that the heat from the impact melted the ice, and that slowly frozen the water to fill the hole。
The density of the surface of the moon is very large, but the average density is very small, so it shows that the density is particularly small. A month-on-month earthquake was also carried out during the month of april, with an seismic instrument on the surface of the moon, and after eight years and 10 months of observation there were also moon shocks on the moon, with a total of 12,458 monthly shocks averaging four times a day, with the largest being the richter category 4, but scientists were shocked when they looked at the waves, and the earthquakes on our planet generally took seconds to dozens of seconds, and the moon could last for hours, and the seismic waves reflected hydraulic resistance, with water in it。
The study found that there were 5 kilometres of rock layers on the moon, and 20 kilometres of metal layers, mainly titanium, which were largely empty, or that there was water, which meant that the moon was a metal ball, which was contrary to the pattern of natural formation of celestial bodies, since natural objects were both central and small。
So the moon is an empty metal ball that never knows when to come from. Beyond that, there are a lot of secrets we don't know about, for example, what's on the other side of the moon, why the united states doesn't go to the moon after it's gone。
While we see the moon every day, it is always waiting for us to open all its secrets with a veil of mystery。
