How fast does the Moon revolve around the Earth?

The average speed of the Moon's revolution around the Earth is kilometers and seconds. The centripetal acceleration of the revolution of the Moon is m s.

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.

Moon. orbiting the Earth in an elliptical orbit; The Moon's orbital period is one sidereal month, which is equal to 27 days, 7 hours, 43 minutes and 11 seconds; 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. The average inclination of the lunar orbit to the Earth's orbit is 5 degrees 9 minutes.

Features of the Moon

The moon itself does not emit light, only reflects sunlight.

The brightness of the Moon varies with the angular distance between the Sun and the Moon and the distance between the Earth and the Moon, and the brightness of the Full Moon is more than ten times greater than that of the upper and lower strings.

The average brightness of the Moon is 1,465,000 of the Sun's, with brightness varying from 1,630,000 to 1,375,000. The brightness of the full moon averages — equal (see). It gives the earth an average of lux, which is equivalent to the illuminance of a 100-watt electric lamp at a distance of 21 meters.

The lunar surface is not a good reflector, its average albedo is only 9%, and the remaining 91% is absorbed by the moon.

The moon revolves around the earth. The moon is actually part of the earth, and in the solar system, both the earth and the moon revolve around the sun, and the moon revolves around the earth.

The moon revolves around the earth, so how long does it take for the moon to revolve in one cycle?

In this magical universe, everyone knows that the moon revolves around the earth, so the moon revolves around the earth, so how long does it take for the moon to rotate a cycle, let's find out together. We learned in geography class that the moon revolves around the earth for a month, and the earth revolves around the sun for a year, because of the rotation of the earth, which is what we often call the time of a day, the time of a day on the earth is 24 hours, and the moon orbits the earth, and the time it orbits around the earth is also a day.

Scientists have calculated that the true orbital period of the Moon is a sidereal month, and the time is days. And we generally use it from the earth, the moon completes a synodic replacement as a month, called a synodic month, and the time is the day. After the Moon has made one revolution around the Earth, it is again facing the distant star, and the Moon has completed one orbital cycle, that is, a sidereal month, and the time is days.

This is the real time for the Moon to make one revolution around the Earth, and it is also the real orbital period of the Moon.

In fact, it can also be explained in other ways such as the moon falling in a gravitational potential well. Regardless of the origin of the Moon, the homology, cataclysmic or captive theory, the initial conditions of the Moon: its linear velocity, direction, mass, and position determine its fate.

Because the Moon is tidally locked, and the Moon's orbit around the Earth also represents a rotation itself, so its revolution and rotation time are the same, so the calculation of the moon's time choking can be identified by referring to the moon's own revolution and autobiography.

Some scientists also say that the time for the earth to circle is 24 hours, and the time for the moon to circle is 648 hours. Last year, only 12 days have passed on the moon, and if we sleep on the moon for one night, plus we sleep 12 hours this night, then half a month has passed on Earth. The earth revolves around the sun is the same, the mass of the sun is 330,000 times that of the earth, the earth is simply too small relative to the sun, it can only orbit around the sun obediently, and the sun occupies the visible matter of the entire solar system.

How long does it take for the moon to revolve around the earth?

It takes a month for the moon to rotate in one cycle, which is the conclusion of scientists after research.

Hours, this refers to the revolution, and the time it takes for the moon to revolve around the earth is relatively long.

I think it takes a month for the moon to turn in one cycle, so I think it's a long time.

The speed at which the Moon revolves around the Earth is kilometers and seconds.

The Moon's orbit orbits the Earth in one complete circle. The centers of mass of the Earth and the Moon are 4,700 kilometers from the Earth's center (times the radius of the Earth's equator), and they each orbit around the center of mass. The average distance between the Moon and the Earth's center is 385,000 kilometers, which is about 60 times the Earth's radius.

The average velocity of the orbit is kilometers and seconds, and the Moon moves about an hour between the background of the stars, which is equivalent to the apparent diameter of the Moon. The Moon's orbit is different from that of most planets' natural satellites, which are close to the ecliptic plane, not the Earth's equatorial plane.

There is an angle between the orbit of the Moon and the orbit of the Earth.

There will only be a lunar eclipse when the Moon is between the Sun and the Earth and near the intersection of the two planes, and the solar eclipse should be regarded as a three-star alignment.

Other planets are not enough to shade the sun because of their distance.

Answer: According to the calculation of the moon's 30 days around the earth, the circumference of the earth is 2 vulr = kilometers, 3600x24x30 days = 2592000 seconds, 40000 25920000 = kilometers, meters and seconds

The rotation and revolution of the Moon are introduced as follows:

The rotation of the moon。The cycle is, this is exactly a constant moon, so we can't see the back side of the moon. This phenomenon, which we call "synchronous rotation", is almost a universal law in the satellite world.

It is widely believed that this is the result of the long-term tidal effect of planets on moons. Balancing movement is a wonderful phenomenon that allows us to see the Moon at 59. There are mainly the following reasons:

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

2) The intersection of the white road and the equator.

The mystery of the moon's rotation. The exploration of rotation was inspired by the method used to calculate the mobility of planar members in the principle of "mechanical design". This can be proven by:

1) Both the Earth and the Moon are celestial bodies that revolve around their respective axes. At this point, the Moon's activity is greater than zero, and the Moon can rotate around its own axis.

2) Suppose the "Earth" is a sleeve that can rotate relative to the center of the Earth, and then use a long rod to weld the Moon and the sleeve together. At this point, the activity of the Moon is equal to zero, but with the rotation of the sleeve (i.e., the relative rotation of the stars), it can rotate around the Earth.

(3) Suppose the Moon is welded directly to Earth with a long rod. At this point, the motion of the Moon around its own axis is equal to zero, it cannot rotate around its axis, nor can it rotate relative to the Earth, but only "rotates" with the Earth.

3.Considering the above two cases2, the Moon rotates around the Earth's axis, but it cannot rotate, it appears to be facing the Earth. From a logical point of view, it is incorrect to call this "rotation" the rotation of the Moon in space.

In both cases, the Moon will not rotate relative to the Earth or relative to the stars.

4.It is fair that two rotating bodies rotate around their respective axes with respect to each other. There is no one around the other axis (rotation) to achieve rotation.

Therefore, only the first case can be used to indicate that the Moon rotates around its own axis. The Moon revolves around its axis, both with respect to the Earth and the Sun. It's just that it's not easy to notice because of its rotational eccentricity and rotational correction offset.

Revolution of the Moon. When the Moon rotates, the center of gravity is deflected under the action of centrifugal force, but the gravitational force is deflected inward under the gravitational force of the Earth. Under the action of these two forces, the Moon rotates around its own axis.

The Moon actually revolves around the Earth on its own axis. Therefore, whether using the Earth as a reference or a star as a reference, the Moon rotates with respect to the Earth.

6.The Moon rotates from west to east. The Moon rotates counterclockwise around the Earth when viewed from the North Pole of the Earth, and the Moon rotates clockwise around the Earth from the South Pole of the Earth. The revolution period is 30 days.

The moon revolves around the earth, and the earth revolves around the sun.

The Sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.

The earth is a planet in the solar system, the sun is the main star of the earth, and the earth revolves around the sun, and one rotation is 1 year in the solar calendar.

The Moon is a satellite of the Earth, and the Moon is also the most massive satellite known to the Earth, forming a celestial system - the Earth-Moon System, and the Moon revolves around the Earth for a lunar month. The average distance between the Moon and the Earth is about 380,000 kilometers, which is about 30 times the diameter of the Earth.

The moon revolves around the earth once in the sky. In addition to orbiting the earth, the moon itself is still rotating, and the cycle of the moon's rotation is 27 days, 7 hours, 43 minutes and seconds, which is almost equal to the period of its revolution around the earth. The Moon is the Earth's natural satellite and one of the first planets to be discovered.

Introduction to the Moon. The Moon is a spherical celestial body that orbits the Earth and is also the only natural satellite of the Earth. In Chinese, it is commonly known as the moon or moon, and in ancient times, it was also called Taiyin, Xuantu, Chanjuan, and Yupan.

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.

Introduction to Earth. Earth is the third planet in the solar system from the inside and outside, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, about 100 million kilometers away from the sun. The Earth rotates from west to east while revolving around the Sun.

At present, it is 100 million years old, and there is a natural satellite - the moon, and the two form a celestial system - the Earth-Moon system.

It takes about a few days for the Moon to orbit the Earth. This number is also known as the moon's "orbital cycle" or "moon cycle". However, the Moon's orbit is elliptical, so it actually takes a slight change in the time it takes to orbit the Earth.

Sometimes the moon's orbital period is slightly longer than the days, and sometimes it is a little shorter.

Supermoon.

The rotation period of the Moon is equal to the rotation period, that is, 1:1, and the time for the Moon to revolve around the Earth is 27 days, 7 hours, 43 minutes and 11 seconds, which is the cavity cycle of its rotation. The result of this peculiar rotation of the moon is as follows:

The Moon always faces the Earth in the same half, and you will never see what the Moon's back is like from the Earth, only by probes.

So, the angle of rotation is about 360° 27 days, 7 hours, 43 minutes and 11 seconds=
