If the moon is solid and able to retain the atmosphere?

The moon is solid, and whether it can retain the atmosphere depends on whether gravity can balance the entropy caused by the diffusion of microscopic particles of gas. This is related to the mass of the Moon, its volume, its surface temperature, and the composition of the atmosphere.

Just know what the moon looks like now.

If it really changes from hollow to solid, there will be no atmosphere on the moon, because there is the earth, the gravitational pull of the earth is large, who can absorb whom, but in that case, the tides on the earth will change, the gravitational force is larger, and the tide will rise more.

The moon itself is solid, and the interior of the star cannot be hollow under the action of gravity.

The interior of the Moon is composed of three parts: the crust, the mantle, and the core. The average thickness of the lunar crust is only 70 km, and the diameter of the lunar core is about 300-425 km.

The mass of the moon is much smaller than that of the earth, according to the law of gravitation, the gravitational force of the same object on the moon is only 1 6 of the earth, and the structure of the moon is --- below

...The moon is hollow?? I don't think there will be a hollow planet

From the birth of the star, what gravity, and so on, the star is not only not hollow, but the more inside, the denser it is, simply put, the more things, the more mass, the greater the haha.

The gravitational pull of the moon is small because it is small, and even if it is all-iron, it does not weigh much.

In addition, what is going on inside the Moon, humanity has not yet understood.

It's hard to say whether the moon is hollow or not, and I personally feel that the hollow sphere is more difficult to understand.

Could it be that you already have conclusive evidence that the moon is hollow?

Because the gravitational pull of the moon is only 1 6 of that of the earth, an object can break free from the gravitational pull of the moon as long as it reaches a speed of 2360 meters per second.

Most gas molecules can reach this velocity under certain conditions. Therefore, even if the moon is constantly producing gas, they will keep leaving the moon and flying into space.

The most important factor in the formation of the atmosphere is the gravitational attraction of the planet itself, that is to say, the atmosphere is the atmosphere formed by the gravitational attraction around the planet... The reason why the Moon does not have an atmosphere is because its gravitational pull is not strong enough to trap gas as an atmosphere. Another example is Mars, the gravitational pull is also relatively small, but it is larger than the moon, so it has a relatively thin atmosphere, and Jupiter, the gravitational pull is abnormally large, so the atmosphere is very thick.
