How far is the moon from the earth?

Question 1: How many kilometers is the earth in distance to the moon? The average distance from the earth to the moon is 384,400 kilometers, and the distance from the perigee of the moon to the earth is 357,000 kilometers (that is, from the surface to the surface of the moon). The farthest apogee from the earth is 406,000 kilometers (that is, plus the diameter of the moon and the earth). The moon is the closest planet to our earth. Usually, the distance between the moon and the earth is about 400,000 kilometers. Because the moon revolves around the earth in an elliptical orbit with an axis as the main axis, the farthest distance from the earth to the moon is 50 thousand kilometers more than in the recent time. It is also a full moon. When the distance to the moon and the earth is the closest and farthest, the apparent diameter of the moon is 14%, and the apparent area is 30% larger. It takes only 1.3 seconds for moonlight to travel from the moon to the earth, which means only blinking. But in such a short time, its distance has exceeded 380,000 kilometers. And the moon's orbit deviates outward at a speed of 3.8cm/a, that is, it is away from the earth at a speed of 3.8cm per year.

Question 2: How many kilometers is it from the earth to the moon? The distance between the earth and the moon is 380,000 kilometers.

The distance to Mars is variable.

The nearest distance is about 55 million kilometers, and the farthest distance is over 400 million kilometers. Close contact between them occurs about once every 15 years. In 1988, the distance between Mars and the earth once reached about 58.8 million kilometers, but in 20 18, the distance between them will reach 57.6 million kilometers. But on August 27th this year, the distance between Mars and the Earth will be only about 55.76 million kilometers, the latest time in 60,000 years. In addition, there will be an astronomical phenomenon that Mars rushes to the sun on the 28th, that is, Mars, the earth and the sun are almost in a straight line.

However, according to astronomers' calculations, during the 800 years from 1600 to 2400, the closest distance between Mars and the Earth this year can only rank third. According to the calculation results, by September 2, 2366, the distance between them was about 557 10000 km. By August 28, 2287, the two will be closer, with a distance of about 55.69 million kilometers.

What is the nearest star to our earth?

The sun, of course, but I don't think this is the answer you want to know! It should be the next nearest star. Besides the sun, the nearest star is proxima centauri Centauri, which is 4.22 light years away from the Earth! ...

Question 3: How far is the moon from the earth? How many months does it take to get there? The average distance to the moon is 38440 1 km. This distance is about 10 times of the equatorial circumference of the earth. The orbit of the moon is elliptical, with an average distance of 363,300 kilometers at perigee and 405,500 kilometers at apogee. The moon is 3476 kilometers in diameter, which is about 3/ 1 1 of the earth's diameter. The surface area of the moon is about114 of the surface area of the earth, slightly smaller than that of Asia. The moon is only 1/49 the size of the earth. The mass of the moon is about 1/8 1.3 of the mass of the earth. The average density of lunar material is 3.34 grams per cubic centimeter, which is only 3/5 of the density of the earth. The gravitational acceleration of a free fall on the lunar surface is 1/6 of that of the earth. The escape speed on the moon is about 2.4 kilometers per second, which is about 1/5 of the escape speed on the earth.
