How far is the Earth from the Moon and how far is the Earth from the Moon

The average distance from the Earth to the Moon is 10,000 kilometers. The closest distance between the Moon and the Earth is 10,000 kilometers, that is, the distance from the surface of the Earth to the surface of the Moon. The farthest distance between the Moon and the Earth is 10,000 kilometers, i.e. plus the diameter of the Moon and the Earth. The Moon is the closest planet to our Earth.

Moon. The Moon is a spherical celestial body that orbits the Earth and is also the only natural satellite of the Earth. In ancient times, the moon was called Taiyin, Xuantu, Chanjuan, and Jade Plate.

The Moon is the fifth largest moon in the solar system, with an average radius of about one kilometer, which is twice the radius of the Earth.

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.

About 380,000 km.

The closest distance from the earth to the moon is 380,000 kilometers, and the farthest time is 400,000 kilometers, if calculated according to the flight time of the speed of light, it only takes about a second for light to go from the earth to the moon, but human technology cannot reach the speed of light, and the human spacecraft does not go directly to the moon, but first flies in the earth's orbit, and then accelerates out of the earth's orbit and into the moon's orbit, which takes hundreds of hours in the middle.

Taking Chang'e-1 as an example, after Chang'e-1 is launched, it will first fly around the earth's orbit for 16 hours, and then the ground will issue an acceleration command, Chang'e-1 will fly to a 24-hour orbit, and then fly to a 48-hour orbit, and finally the ground will issue a command to go to the moon, and Chang'e-1 will accelerate to the lunar orbit, which will take 5 days halfway, and a total of about 8 days, so it is not so simple for human vehicles to fly to the moon, but to fly to the moon gradually by flying around orbit, with the current technology of human beingsThere is no way to reach the speed of light like that, it takes 1 second to reach the moon.

The average distance between the Earth and the Moon is 384,400 kilometers.

If a person were to move kilometers per second at the speed of light, it would only take about a second or so to get from the Earth to the Moon. After research, the Moon is leaving the Earth at a distance of four centimeters per year. The distance between the Moon and the Earth's perigee is 10,000 kilometers; The farthest apogee distance from Earth is 10,000 kilometers.

A method of measuring the distance between the Earth and the Moon.

Over the past few decades, humans have placed multiple corner mirrors on the surface of the moon through lunar spacecraft, including Apollo 11, Apollo 14, and Apollo 15 in the United States; The Soviet Union's Luna-17 (Luna Rover 1) and Luna-21 (Luna Rover 2), among others, used a ground observatory to measure the round-trip time (equivalent) using a laser to calculate the distance between the two. At present, with the help of these artificial instruments, the measurement accuracy of the distance between the Earth and the Moon can reach the order of millimeters.

About 380,000 km.

The average distance between the Moon and the Earth is about 380,000 kilometers. But because the Moon orbits the Earth in an elliptical orbit, the Moon is 50,000 kilometers farther away from the Earth than it was at its closest. The motion of the Earth and the Moon is more like a dance, and their masses are not very different, so they form a binary-like system that revolves around their common center of mass.

The Earth is about 380,000 kilometers from the Moon. The Moon may have been formed about 4.5 billion years ago, shortly after the formation of the Earth, and there are several hypotheses about its origin, which are supported by more factual evidence, and the theory is that it was formed by the debris produced by a huge impact between the Earth and the Mars-sized celestial body "Theia", which gathered in the outer periphery of the Earth.

The front side of the moon is dotted with huge impact craters filled with basalt lava flows ejected from dark volcanoes, forming a vast plain called the "Moon Sea", in fact, there is not a drop of water in the "Moon Sea". Between the outer and lunar seas are bright, ancient plagioclase highlands and conspicuous impact craters.

The Moon moves half a degree per hour relative to the background starry sky, i.e. it is similar to the apparent diameter of the Moon's surface. Unlike other satellites, the Moon's orbital plane is closer to the ecliptic plane than near the Earth's equatorial plane. The time it takes for the Moon to orbit the Earth (one sidereal month) is called a sidereal month, relative to the background starry sky; Whereas the time it takes for a new moon to take for the next new moon (or between two phases of the same moon) is called a synodic month.

The synodic moon is longer than the sidereal moon because the Earth itself travels some distance in its orbit around the Sun during its orbit.
