Why does the moon stay some distance from the earth?

Upstairs, a broad definition and basic trajectory of the moon have been popularized. I think the question the landlord wants to ask is why the moon is not attracted to it, or flies out of the earth, but keeps a certain distance around the earth. Let me briefly say that the moon revolves around the earth because the earth's gravity pulls the moon, so the moon is close to the earth, so why doesn't the moon come to hit the earth, because it has speed, he is rotating around the earth, and any object that does circular motion has the ability to break free, and when this breaking force and the earth's gravitational pull on the moon perfectly cancels out, then the moon can only keep a certain distance from the earth and rotate around it.

Finally, I think the landlord may have a lot of hypothetical questions, here is a little bit of speculation about the formation of the moon, scientists said that the moon was once a meteorite or meteor that flew into the solar system, and the trajectory of flying into the solar system was just cut close to the earth, and the speed of the flight was perfectly pulled by the earth's gravity, so when it flew it was pulled by the earth, forming a satellite of the earth, generally speaking, the longer the time, the greater the mass of the planet, the ability to capture the satellite will be greater, There are more moons, such as Saturn and Jupiter, and of course these are also speculations. If you are interested, you can search for words like "capture the moon", and there will be many surprises. Ha ha.

Hope it helps.

The moon is a satellite of the earth, always orbiting the earth in an elliptical orbit, this is because the earth has a gravitational effect on the moon, so that the moon orbits the earth, and at the same time, the earth and the moon are subject to the gravitational force of the sun at the same time, and jointly orbit the sun. The perigee distance between the Moon and the Earth is 363,300 km and the apogee is 405,500 km. Generally speaking, the average distance is 380,000 kilometers.

It is an elliptical orbit. And the interesting thing is that one side of the moon is always facing the earth, and the other side of the moon is not visible to us on the earth, of course, now we humans have a lunar probe, and we can observe the other side of the moon through the lunar probe.

Twins will keep a distance, not to mention the moon and the earth, and they will not be conjoined fetuses.

The lunar distance refers to the average distance between the Moon and the Earth as about 60 re), and the angle of intersection between the orbital plane of the Moon around the Earth and the equatorial plane of the Earth is 5. It is a unit of length in astronomy. The average distance from the Earth to the Moon is about 10 times the circumference of the Earth's equator.

The diameter of the Moon is 3476 km, which is about 3 11 of the diameter of the Earth. The surface area of the Moon is about 1 14 of the Earth's surface area, which is slightly smaller than the area of Asia. The volume of the Moon is only 1 49 of the volume of the Earth. The mass of the Moon is approximately equal to 1 of the mass of the Earth.

Perigee. The Moon's perigee to Earth is 363,300 kilometers.

Apogee. The farthest apogee distance from Earth is 405,493 km.

The Moon, with its gentle gravitational pull (about Newton), gently tugged at the Earth, directly contributing to the development of life from the oceans to the land. The area of the Earth directly facing or facing away from the Moon is pulled up by this force. If this is the ocean, tides will form.

There are two ebb and flow times for every rotation of the Earth. The moon tide brings organic-rich waters to the edge of the land. At the junction of land and sea, some aerobic organisms survived tenaciously and became the earliest land organisms.

The Earth and the Moon orbit each other, and the two celestial bodies rotate around a common center of gravity 1,600 kilometers below the surface. The birth of the moon has added a lot of new things to the earth.

A long, long time ago, the earth had a large temperature difference between day and night, and the temperature was between the boiling point and the freezing point of water, which was unsuitable for human habitation. However, the special influence of the moon on the earth's seawater slows down the earth's rotation and revolution speed, makes the earth's rotation and revolution cycle tend to be reasonable, brings us precious four seasons, reduces the temperature difference, and is suitable for human habitation.

The Moon is the most studied by people.

Images of the moon (16 photos) thoroughly celestial bodies. The age of the Moon is about 4.6 billion years. The Moon, like the Earth, has a layered structure such as a shell, mantle, and core.

The average thickness of the outermost lunar crust is about 60-65 km. Below the lunar crust to a depth of 1,000 km is the lunar mantle, which occupies most of the moon's volume. Underneath the mantle is the lunar core, which is about 1000 degrees warm and most likely molten.

The diameter of the moon is about 3476 kilometers, which is 1 4 of the earth and 1 400 of the sun, and the distance from the moon to the earth is equivalent to 1 400 of the distance from the earth to the sun, so the moon is as big as the sun from the earth. The volume of the Moon is only 1 49 of the Earth, and the mass is about 735 billion tons, which is equivalent to about 1 80 of the Earth's mass, and the gravity of the lunar surface is about 1 6 of the Earth's gravity. The Moon, the Earth's only natural satellite, is the closest celestial body to us, with an average distance of about 384401 kilometers from the Earth.

Its average diameter is about 3476 km, which is slightly larger than 1 4 of the Earth's diameter. The Moon's surface area of 38 million square kilometers is large, but not as large as that of Asia. The mass of the Moon is about 735 billion tons, which is equivalent to 1 81 of the mass of the Earth, and the gravity of the Moon is almost equal to 1 6 of the Earth's gravity.

Orbital motion 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.

Revolution period day. The minimum temperature at the surface is 183 degrees Celsius.

The Moon is located on average 384,401 kilometers from Earth. This distance is about 10 times the circumference of the Earth's equator.

The Moon is located at an average distance of 384,000 kilometers from Earth.

If the Moon were a little closer to Earth, the following changes could occur.

1. The Moon must speed up its revolution, so the duration of a synodic month will be shortened.

2. Due to the increase of the gravitational attraction of the moon, the tidal water level will change greater, and the coastal areas may be transgressed by the sea, and the tidal flat area will increase.

3. The tidal locking of the moon on the earth is enhanced, the earth's self-transformation is slow, and the time of day is extended.

4. The perspective of the moon becomes larger, and the moon is larger and brighter at night.

5. When a solar eclipse occurs, the probability of a total solar eclipse increases, and the eclipse duration is prolonged.

That's about it.

1. The distance between the earth and the moon is Yu Chaidou.

2. The distance of the moon refers to the average distance between the moon and the earth is about 60re), and the angle of intersection between the orbital plane of the moon around the earth and the equatorial plane of the earth is 5. It is a unit of length in astronomy. The average distance from the Earth to the Moon is about 10 times the circumference of the Earth's equator.

3. The diameter of the lunar vertical grinding ball is 3476 kilometers, which is about 3 11 of the diameter of the earth. The surface area of the Moon is about 1 14 of the Earth's surface area, which is slightly smaller than the area of Asia. The volume of the Moon is only 1 49 of the volume of the Earth.

The mass of the Moon is approximately equal to 1 of the mass of the Earth.

4. Perigee: The perigee distance of the Moon from the Earth is 363,300 kilometers. Apogee: The farthest apogee distance from Earth is 405,493 km.

Theoretically, yes. In the case of the most supported collision, Theia will slowly move away from the Earth after colliding with the primordial Earth, and this number is an astronomical unit, which is not something we can imagine today. Suppose flying out of the Earth's gravity and forming a new planet is an inevitable result.

It originally belonged there.

Some speculate that Theia may have been a Trojan asteroid, composed of water and ice, which brought water to Earth after it collided with the primordial Earth, and the Earth and Theia produced a large amount of debris, which recombined to form the Moon. Of course, this is a hypothesis, and for the time being, it is considered a way to answer this question. It's as if Theia brought water to the Earth, completed the mission and left with a part of the Earth.

According to the results of human measurements of the distance between the earth and the moon, the moon is indeed moving away from the earth at a certain distance every year, if you want to know whether the moon will completely leave the earth, you must first know the reason why the moon is far away from the earth, we know that the moon is a natural satellite of the earth, and it has a very important role in the development of the earth's ecological environment.

Because the moon has a gravitational effect on the earth, and because the tide is locked, the moon only rotates, there is no rotation, and the speed of the moon is less than the earth's rotation, and the mass of the moon is unchanged, then the moon itself only has potential energy and kinetic energy, and this speed difference will make the liquid water on the earth's surface produce tides, the tide itself is a kind of energy, part of this energy comes from the moon's gravitational pull on the earth, after all, there is also the sun.

Of course, we also know that the influence of tidal energy is to make the earth's self-transformation slow, according to the law of conservation of energy, the moon inputs energy to the earth, the moon can only reduce energy by reducing the speed of revolution, from the law of circular motion, the decrease in the orbit of the celestial body will lead to a higher orbit, that is, the distance between the moon and the earth is getting farther and farther, so we can see that as long as the moon still has a gravitational pull on the earth, then the liquid water on the earth's surface must be affected by gravity, and the moon is losing speed all the time, It's just a matter of size, and year after year, the distance between the Earth and the Moon gets bigger and bigger.

The reason is that because of gravity, from a purely mathematical point of view, there is gravitational attraction between any two celestial bodies, so over time, the moon will definitely be completely away from us one day, and when the conditions are ripe, the moon will be captured by other celestial bodies and become satellites of other planets, so if you can live until that day, then you will not be able to see the moon when you look up at night.

At this rate, one day in the future, the moon will leave the earth completely, and we will never see the moon again.

The moon belongs to the satellites of the earth, and the moon has its own orbit. The Moon revolves around the Earth every 27 days. The moon is not far from the earth.

I don't think the moon will leave the earth completely in the future, because the moon is very important to each of us.

The answer is yes. Don't look at centimeters too much, you must know the truth that small things add up. After a few years, the moon was no longer visible on Earth.
