The moon isn't round, and neither is the Earth, and the moon is spherical, but the surface is cratered, uneven, and when you look at the moon, you have dark spots, and it's a sunken part, like a valley, like the sun casts its shadow in a valley when it shines on a mountain.
The shape of the moon is also a slightly flattened ball at the north and south poles and slightly uplifted at the equator. Its mean polar radius is 500 meters shorter than the equatorial radius. The Antarctic region is also asymmetrical, with the Arctic region uplifted and the Antarctic region depression of about 400 meters.
The center of gravity of the moon does not coincide with the geometric center, and the center of gravity is 2 kilometers away from the Earth. This conclusion has been made"Apollo"This is confirmed by the information obtained from the moon landing.
But what we usually see is only one side of the moon, that is, the moon revolves and rotates almost as fast, and the other side says, for"Apollo"It is also difficult to say what the information obtained from the moon landing confirms, because"Apollo"There are many doubts about the moon landing itself, such as that there is no air on the moon, and it is said that it should not be caused by the wind, but the American flag in ** is flying.

It depends on your position, you stand on the moon, look around it will think it is flat, you look at it from a distance and it will feel arc-shaped, but it also has potholes. On Earth, he looks like a big disc pulling!! Ha ha.
-
It is a round sphere with an uneven surface, but it is still round.
-
Up in the air! The history of the moon is more distant than that of the Earth!
-
The clump is round at a distance, but at near it is uneven
-
The rotating planet is definitely fat at the equator and the poles are contracting. Now the pear-shaped shape of the earth is explained in this way, because the rotation produces centrifugal force, so the equator is thrown away, then the poles will contract, and they are all Poissons.
-
Is the Earth round? The Moon is about the same as the Earth.
-
Because the earth, the moon, and the sun all have a large gravitational pull that attracts objects on the surface of the sphere close to the center, they are all round.
-
Because the gravitational pull is greatest in the interior of each planet, it compresses the surrounding matter towards the center and becomes a circle.
-
This is because of the gravitational pull that exists on these stars, as well as the pressure in the atmosphere, which causes these forms to be round.

The moon is not hollow.
The moon is a spherical celestial body that revolves around the Earth and is also a natural satellite of the Earth. In Chinese, it is commonly known as the moon or moon, and in ancient times, it was also called referring to the world as Taiyin, Xuantu, Chanjuan, and Jade Pan.
The Moon is the fifth-largest moon in the solar system, with an average radius of about kilometers, which is equivalent to times the radius of the Earth; The mass is close to kilograms, which is a double of the ground return ball.
On May 16, 2019, the National Astronomical Observatories of the Chinese Academy of Sciences announced that a research team led by Li Chunlai, a researcher at the Chinese Academy of Sciences, used the Chang'e-4 probe data to prove the existence of deep materials dominated by olivine and low-calcium pyroxene in the South Pole-Aitken Basin on the far side of the Moon. The international academic journal Nature published this significant discovery. [2]
At noon on October 26, 2020 local time, NASA's Stratospheric Infrared Astronomical Observatory "Sophia" confirmed for the first time that there was water on the sunny surface of the Moon. [3]
At 23:11 on December 1, 2020, Beijing time, China's Chang'e-5 probe landed for the first time in the area north of the Lumke Mountains on the far side of the Moon [15] ; At 23:10 on December 3, the Chang'e-5 ascender took off from the lunar surface with about two kilograms of samples, and began to return to Earth after completing the docking and transfer work with the orbiter.
This is a well-known rumor, and there is no substantial evidence that the Moon is hollow. I heard that this rumor first appeared mainly because the density calculated by the volume and total mass of the moon is smaller than the actual ore of some moons, so some people speculated that there was a hole in the middle. In fact, we all know according to common sense that if I find some ores from the earth that are denser than the average density of the earth, it is obviously not correct to say that the earth is hollow, not to mention that human beings have mined very little lunar ore, which does not explain anything at all. >>>More
The Earth is a sphere, but due to gravity, it is not a perfect sphere, and the equator bulges outwards to form a "spare tire" structure. In fact, the polar radius of the Earth is kilometers, while the radius of the equator is kilometers.
How to prove that the earth is round?
I think it is; Because:
On November 20, 1969, the lunar module of "Apollo 12" "Intrepid" suddenly lost control and crashed on the surface of the moon, and recorded up to 15 minutes on the high-sensitivity seisismometer 72 kilometers away from the crash site**, if it is only 3-5 minutes at most on the earth**, scientists preliminarily conclude that the moon is a huge hollow ball. >>>More
It was only after reading the last graduate school entrance examination exercises that I decided that I wanted to take the exam, because after reading those things about the graduate school entrance examination, I felt that such an example had no value at all, it was too simple, so I had enough confidence in myself to be able to pass it over and over again.
