More than 200 new craters have been discovered on the moon. Why is the moon hit by so many meteorites?

It can be said that there are craters on any planet, and which planet has the most craters near us is our little brother-the moon. We are all very familiar with the appearance of the crater on the moon. So do you know how many craters there are on the moon? You may not be able to answer, because science can't give an accurate figure so far, because the discovery of craters on the moon continues. If we only estimate from the theoretical level, there may be hundreds of thousands of craters on the moon. Yes, you are right, that is100000. And in my opinion, this number is conservative, because just last month, scientists discovered more than 6,000 craters on the moon.

Please note that it is a newly discovered crater, not a new crater. Don't mistakenly think that the moon is attacked by 6000 meteorites a month, which is terrible. As we all know, the crater is a sinkhole formed by the impact of meteorites. Such a large number of craters on the moon fully illustrates the process of the moon being hit by meteorites many times in history. Then the question is, the distance to the moon is so close to the earth, and the gravity of the earth is stronger than that of the moon. Why do hundreds of thousands of meteorites attack the moon, but few people care about the earth? Because there is a huge difference between the earth and the moon, and this difference is the atmosphere. As we all know, there is no atmosphere around the moon, which means that meteorites will not be hindered in the process of hitting the moon.

But the earth is different. The earth is protected by a thick atmosphere. If the volume and density of meteorites do not reach a certain level, they will burn out in the process of entering the atmosphere and disappear into the air before falling to the ground. Of course, this is just one of the reasons why there are few craters on the earth. Another reason is that craters won't last forever. From the moment of its birth, craters will be affected by weather activities and geological movements, such as water friction and weathering on the surface of craters, which will gradually kill craters. Over time, the crater will disappear. These geological movements and weather activities are very abundant on the earth, so few craters remain.

So do many planets in the universe. Although it is often hit by meteorites, the crater is quickly worn out due to rich weather activities. This is why the moon can be one of the planets with the most craters near us. There is almost no weather activity on the moon, so the speed of killing people in craters is very, very slow. With the passage of time, so many craters have accumulated.
