The mysterious celestial body that formed the moon is smaller than expected. What is the reason?

In fact, it is known that the moon collided with the earth billions of years ago to form a moon shape that lasted for billions of years. In fact, the mass of this celestial body is smaller than we thought in recent years. The moon we usually know through telescopes and the internet seems to be relatively large, but it is actually smaller than we thought, because it may be related to the previous collision and explosion and our cognitive range, so everyone may think that the moon is one from small to large.

Recently, many computers or experiments actually simulated a collision 265,438+0 years ago to form the moon. From the whole conclusion, in fact, after the moon collided with the earth, the mass may be around110. For a long time, astronomers have been speculating that the collision between the giant round star of the moon and the early earth was put forward in the 1970s. Researchers pointed out that the biggest collision event produced a large number of debris and eventually merged into the moon, which is also an incomplete combination. Although astronomers in Kazakhstan have so far been unable to explain the consistency of debris between the moon and the earth, scientists have put forward some views. After the collision, the two halves of the earth formed the earth-moon system, followed by the collision of small high-speed projectiles with large volume and fast rotation.

In order to reveal the fact that the formation and mass of the moon are less than expected, the Paris Institute of Geophysics and colleagues are now analyzing it. Through collision simulation, it is found that the collision weather whose mass exceeds the earth's mass 15% cannot produce the chemicals we see in the mantle layer, and its collision with the earth will lead to a large amount of cobalt and nickel on the ground. Recently, an independent research institute found that shortly after the formation of the moon, the earth was hit by an asteroid, which brought a lot of rare elements to the earth.

So in general, the moon is actually a combination of various debris celestial bodies, rather than an independent celestial body. In addition, the material attraction on the surface of the moon is small, and the volcanic eruption on it is relatively large. In addition, there is no air and water on the moon, and there is no wind and rain erosion. It has always maintained its original mass shape. Therefore, the mysterious weather that forms the moon is mainly debris, so it is much smaller than expected.
