The fifth largest moon in the solar system is the Moon, is it solid?

In the solar system, the moon, as the fifth largest moon, has two major theories about whether it is solid, one is the "moon solid theory" and the other is the "moon hollow theory". The current prevailing view is that the Moon is not solid, it is hollow.

In the 60s of the 20th century, some scientists put forward the idea that the moon is a hollow planet based on the fact that the density of the moon is lower than that of the earth, that is, the "lunar hollow theory". So far, although there is some evidence to support the "lunar hollowness theory", there is still a huge controversy about the reliability of this theory.

1. Human Lunar ExplorationWith the progress of science and technology, human beings have successfully landed on the moon and started the journey of exploring the moon. The cratered surface of the moon and its clear distinction between light and darkness have given mankind a great shock. In the process of human exploration of the moon many times, there is no specific answer to whether the moon is hollow or solid, and most people now believe that the moon is hollow.

2. Scientific ExplorationIn April 1970, Apollo 13 successfully explored the moon and sent back the echo of the moon's "moonquake", and through observation and analysis of this echo, scientists came to the conclusion that the moon may be a hollow sphere. At the same time, scientists have found that the density of the Moon is smaller than that of the Earth, as well as observations through the Moon's orbital circulator, which have led to further positive conclusions that the Moon is most likely a hollow planet.

3. The controversy that has always existed whether the moon is hollow or solid This is a controversial issue that has always existed, and different people have different opinions. This is actually a normal phenomenon. Just like the earth we live on now, human beings have not been able to determine whether it is hollow or solid.

But the prevailing view we can be sure of is that the Moon is hollow.

With the continuous progress and development of science and technology, we believe that whether the moon is solid or not will be explored in the future.

In ancient times, the ancients' worship of the moon can be said to be like a surging river, but with the development of science and technology, human beings went to space and found that the moon was only a satellite of the earth. To put it bluntly, it is the moon, which is just a small part of the earth, and it follows the earth every day. Of course, the status of our earth is not high among the celestial bodies, and it revolves around the sun every day.

But in any case, the Moon, as our neighbor, is currently the largest celestial object that humans can see with the naked eye. <>

However, with the research of scientists, it has been found that the position of the moon in the solar system is very unusual, because compared with several other moons, the moon appears to be very large. This is not to say that the Moon itself is large, because the Moon is the smallest of the five major moons, mainly because the other moons are generally 1:1000 in volume compared to the planets around them.

The volume ratio of the moon to the earth is maintained at 1:49, which can be said to be a very special existence in the solar system. <>

And in addition to its large size, the mass of the Moon is also very different from that of other satellites. Its mass is obviously not as large as its volume, so many people wonder if the interior of the moon is hollow after all. However, although the lunar rover can now conduct some scientific expeditions on the moon, the area that can be explored is still very small, especially in some lunar craters, and our signals cannot be connected to it at all.

As a result, human exploration of the depths of the earth is still unknown. However, scientists have also found that the role of the moon on the earth is far beyond our imagination, and as a satellite, the moon is constantly absorbing some cosmic dust from space and attaching it to the surface of its own planet. This has led to an increase in the mass of the Moon, and it has also been observed that the Moon is constantly escaping the Earth at a rate of centimeters per year, which shows that the mass of the Moon is too large compared to the Earth's gravitational pull, and it is gradually getting out of the Earth's control.

According to the results of current scientific exploration, it is likely that the moon is not solid but hollow, because some scientists believe that the density of the moon is lower than that of the earth, so many people now believe that the moon is hollow.

The moon is hollow, and the American astronaut Apollo tested the **wave on the moon after landing on the moon, and it was found that the **wave lasted very long and was not transmitted to the interior of the moon.

The moon is solid, it is not hollow, the moon we see is the moon, the moon we see is round, that is, the moon is not covered by any object, and when we see the moon is scimitar-shaped, there is something covering the moon.

The largest moon in the solar system is Triton, and the Moon is the fifth largest moon in the solar system.

Triton is Neptune's largest natural moon and the first moon to be discovered.

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 twice that of the Earth. The surface of the Moon is covered with craters formed by the impact of small celestial bodies. The average distance between the Moon and the Earth is about 10,000 kilometers, about 30 times the diameter of the Earth.

Europa is the largest moon in the solar system, with the Moon in fifth.
