The average distance from the Earth to the Moon is 384,400 km, and the Moon's perigee distance from the Earth is 10,000 km (i.e., from the surface to the lunar surface); The farthest apogee distance from the Earth is 10,000 kilometers (that is, plus the diameter of the Moon and the Earth).
The Moon is the closest planet to our Earth. Normally, the Moon is about 400,000 kilometers away from the Earth, and because the Moon orbits the Earth in an elliptical orbit with a main axis, the Moon is 50,000 kilometers farther away from the Earth than it was at its closest. Also a full moon, when the Moon is closest and farthest from the Earth, the apparent diameter of the Moon is 14% larger and the apparent area is 30% larger
It only takes a second for moonlight to travel from the moon to the earth, which means that it only blinks an eye. However, in such a short time, it has a distance of more than 380,000 kilometers. And the orbit of the Moon is shifting outwards at a rate, that is, away from the Earth at a rate of centimeters per year.

The Moon is 384401 kilometers away from the Earth.
The Moon will move farther and farther away from Earth.
The main reason: the earth's 2 tides a day (tidal energy can generate electricity) are caused by the gravitational pull of the earth and the moon This huge energy is consumed every day, and the earth's ability to bind the moon is getting weaker and weaker The mass center of the entire Earth-Moon system will be farther and farther away from the earth At present, the mass center of the Earth-Moon system is still in the interior of the earth, about 1600 kilometers below the ground, and the center of the earth (the mass center of the earth) is 6300 kilometers below the ground The distance between the two will continue to increase Stay away from about 4 cm or so per year Reference: baidu

384,400 km. The average distance between the Earth and the Moon is 384,400 kilometers.
The average distance from the Earth to the Moon, a unit of length in astronomy.
Moon distance is an astronomical unit of length that is generally used to measure the distance between celestial bodies in space. The value of the distance to the moon in January is. The average distance from the Earth to the Moon is about 10 times the circumference of the Earth's equator.
The earliest person to determine the distance between the moon and the earth was reported in 180 BC at Iba Valley. Nowadays, scientists have used advanced laser technology to accurately measure the distance of the moon and conduct a more thorough study of the moon.
Moon distance: The average distance between the Moon and the Earth is about 60re), and the angle of intersection of the orbital plane of the Moon around the Earth and the equatorial plane of the Earth is. Moon distance is now used as an astronomical unit of length. 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.

There are three types of Earth-Moon distance: average distance, distance between the Moon and the Earth's perigee, and distance between the Moon and the Earth's apogee. The average distance between the Earth and the Moon is kilometers. The distance between the Moon and the Earth's perigee is 10,000 kilometers, and the distance from the Earth's apogee is 10,000 kilometers.
Studies have shown that the Moon will move farther and farther away from the Earth as the Earth's rotation becomes slower and slower. Every year the Moon moves about centimeters away from the Earth.
In normal times, the Moon is about 400,000 kilometers away from the Earth. In special periods, the moon is about 50,000 kilometers farther away from the earth than it was at its closest, and this data is still changing.
When the Earth is closest and farthest from the Earth, the apparent diameter of the Moon is 14% larger and the apparent area is 30% larger. The reason why the Moon is moving farther and farther away from the Earth is caused by the common gravitational pull of the Earth and the Moon.

The distance between the Earth and the Moon is 380,000 kilometers.
The distance to Mars is more variable.
The closest distance is about 55 million kilometers, and the farthest distance is more than 400 million kilometers. Close encounters between the two occur approximately once every 15 years. In 1988, the distance between Mars and Earth reached about 58.8 million kilometers, and in 2018 the distance between the two will reach 57.6 million kilometers.
But on August 27 this year, Mars will be only about 55.76 million kilometers away from Earth, the closest in 60,000 years. In addition, there will be an astronomical phenomenon of Mars opposition on the 28th, that is, Mars, the Earth, and the Sun are almost in the same straight line.
However, astronomers estimate that in the 800 years from 1600 to 2400 AD, Mars will only rank third closest to Earth this year. According to the projections, the distance between the two will be about 55.71 million kilometers by September 2, 2366. By August 28, 2287, the two will be closer, with a distance of about 55.69 million kilometers.
What is the closest star to our Earth?
That's the sun, of course, but I guess that's not the answer you want to know! It should be the next closest star, except for the Sun, the closest star to us is Proxima Centauri, light years from Earth!

The average distance from the Earth to the Moon is 384,400 km.
The moon is a spherical celestial body that revolves around the Earth and is also a 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.
Explanation of terms: The Moon is the fifth largest satellite in the solar system, with an average radius of about one kilometer, which is equivalent to a multiple of the Earth's radius; 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.
On May 16, 2019, the National Astronomical Observatories of the Chinese Academy of Sciences announced that a research team led by Li Chunlai, a researcher at the Chinese Academy of Sciences, used the Chang'e-4 probe data to prove the existence of deep materials dominated by olivine and low-calcium pyroxene in the South Pole-Aitken Basin on the far side of the Moon. The international academic journal Nature published this significant discovery.

The distance between the Earth and the Moon is about 384,400 kilometers.
Because the Moon orbits the Earth in an elliptical orbit, it has the closest and farthest distances. The perigee distance is 363,300 km; The apogee distance is 405493 km; The average distance between the Moon and the Earth is about 380,000 kilometers, which is about 30 times the diameter of the Earth.
In ancient times, the moon was also known as Taiyin, Xuantu, Chanjuan, and Yupan, which was the satellite of the earth and the fifth largest satellite in the solar system. The Moon is about a quarter of the diameter of the Earth and about one-eighty-one times the mass of the Earth. The Moon is the most massive moon known to Earth, and its surface is covered with craters formed by the impact of small celestial bodies.
A method for determining the distance between the Earth and the Moon by the Ancient Cracked Hail
The earliest ancient people to measure the distance between the moon and the moon were through visual observation, and the first person to measure the distance between the moon and the earth was Ibargu, who was born around 180 BC in Asia Minor, which is now Turkey.
Ibacoku invented a "sight", a wooden pole about two meters long, with a groove to allow a baffle to slide in, and a plate with a small hole was erected at one end of the pole, from which the human eye could observe the stars, and at the same time slid the baffle so that it just covered the target. According to the distance between the baffle and the small hole and the width of the baffle, the relative size of the measured object or the apparent distance between two points in the starry sky can be calculated.
The safety distance is the distance between the front of the vehicle and the rear of the vehicle in front. When driving on a highway and the speed of the vehicle is more than 100 km/h, the safe distance should be more than 100 meters. When the speed of the vehicle is above 60kmh, the safe distance should be equal to the speed; For example, at a speed of 80 km/h, the safe distance between the vehicles is 80 meters. >>>More
