Does the moon have an outer sphere, does the moon have an outer sphere

The Moon had an atmosphere in the distant past, but because its gravitational pull was too small, it simply could not preserve its atmosphere! Over time, the atmosphere will disperse into space, so now there is no atmosphere on the moon!

First of all, there is no circle on the surface of the moon.

The Moon is the only natural satellite of the Earth, and it has a close evolutionary connection with the Earth. Based on the analysis of the Apollo 11 and 12 lunar seismological observators built on the moon, as well as the study of the lunar surface and lunar rocks, it is known that the current lunar interior also has a sphere structure, but it is not exactly the same as the inner sphere structure of the earth. The surface of the moon has a layer of lunar soil that is several meters to tens of meters thick.

The entire Moon can be considered to consist of the lunar lithosphere (0 1000 km), the asthenosphere (1000 1600 km) and the lunar core (1600 1738 km). The lunar lithosphere can be further divided into four layers, namely the lunar crust (0 60 km), the upper mantle (60 300 km), the middle mantle (300 800 km) and the lunar seismic zone (800 1000 km). The asthenosphere is also known as the lower mantle.

At depths of 10 km, 25 km and 60 km of the lunar crust, there are sharp changes in the velocity of lunar seismic waves, indicating significant discontinuities at these depths. The surface of the moon to a depth of 25 km is the first layer of the lunar crust composed of basalt, and the second layer of the lunar crust between 25 km and 60 km, composed of gabbro and pyrorite. The upper mantle is composed of magnesium-rich olivine, and the middle and lower mantle are composed of mafic rocks.

The location of the lunar hypocenter is located between the depths of 600 1000 km, and the average lunar source depth is 800 km. Since the density of the rocks on the surface of the Moon is not much less than the average density of the entire Moon, it can be assumed that the core of the Moon will not be composed of heavier elements such as iron and nickel, and it may be plastic or partially molten. At a depth of 1,000 km on the Moon, the temperature of the lunar mantle will not be higher than 1,000 ° C.

Based on what is known about the inner state of the Moon, the solid partial sphere structure is not unique to the Earth itself. The above-mentioned sphere structure of the Moon is also the result of the differentiation of the entire lunar material sphere during the evolution of the Moon.

No... There is no life on the moon, no carbon dioxide can be made, no atmosphere can be formed

There is no circle on the surface of the Moon. Due to the small mass of the Moon, it cannot produce enough gravitational force to adsorb a large number of gas milling molecules on the surface of the Moon, so there is no Mintong atmosphere on the Moon, and there is basically no bridge in the outer sphere.

Revolution of the Moon. The Moon orbits the Earth in an elliptical orbit. The great circle of this orbital plane on the celestial sphere is called the "white path".

The plane of the white channel does not coincide with the celestial equator, nor is it parallel to the plane of the ecliptic, and the spatial position is constantly changing. Cycle day. The average inclination of the lunar orbit (white path) to the Earth's orbit (ecliptic) is 5°09.

But it is known that the Moon is gradually departing from the Earth at an average rate every year.

The rotation of the moon. The Moon rotates while revolving around the Earth, and the period day is exactly a sidereal month, so we can't see the far side of the Moon. This phenomenon is called "synchronous rotation", or "tide locking", and is almost a universal law in the world of solar system satellites.

It is thought to be the result of the long-term tidal action of satellites on planets. The balance movement is a wonderful phenomenon that allows us to see 59% of the surface of the moon. There are mainly the following reasons:

1) In different parts of the elliptical orbit, the rotation speed does not match the angular velocity of the revolution.

2) The intersection of the white and equator.

Summary. No. The Earth's outer sphere includes: the atmosphere, the hydrosphere, and the biosphere. The moon is too small to bind the atmosphere, so there is no water or life. Naturally, there is no outer circle.

Does the Moon have an outer sphere + which book is excerpted from.

No. The Earth's outer sphere includes: the atmosphere, the hydrosphere, and the biosphere. The moon is too small to bind the atmosphere, so there is no water or life. Naturally, there is no outer circle.

Which book is it taken from.

The answer is taken from knowing <>

Some learning interactive classes** and some astronomical magazines are also described.

Well, thanks. You're welcome, and I hope my answer helps. I wish you all the best and good health.
