In terms of size, the Earth is about 49 times larger than the Moon. In terms of diameter, the Earth is about twice the size of the Moon. In terms of volume, the Earth is about 8 times larger than the Moon.
In terms of mass, the Earth is about 81 times larger than the Moon. The diameter of the Earth is 6,378 kilometers and that of the Moon is 1,738 kilometers.
Earth, the third planet in the solar system from the inside and outside, is also the terrestrial planet with the largest diameter, mass and density in the solar system, about 100 million kilometers from the sun.
The Earth rotates from west to east and revolves around the Sun at the same time, which is now 100 million years old, and forms a celestial system with the Moon - the Earth-Moon system.
The radius of the Earth's equator is about 1,000 kilometers, the polar radius is about 1,000 kilometers, the average radius is about 6,371 kilometers, and the circumference of the equator is about 40,075 kilometers.

With a diameter of 6,378 kilometers, the Earth is the terrestrial planet with the largest diameter, mass and density in the solar system, about 100 million kilometers away from the Sun. The Moon is the fifth largest moon in the solar system, with an average radius of about kilometers. The average distance between the Moon and the Earth is about 10,000 kilometers, about 30 times the diameter of the Earth.
The highest mountain on the moon is higher than Mount Everest.
There are a lot of craters on the moon, although it looks very small on the crater, in fact, the edge of these craters is lined with peaks, and the average height of many mountains is three or four thousand meters higher than the plains on the moon (also known as the moon sea), they are all large asteroids after hitting the surface of the moon, the huge impact force displaces the crust of the moon, and the first part of the impact collapses.
The edge part is squeezed and uplifted by the ** part, so in a short time, the edge of the crater will form a mountain range, which usually only occurs in one minute, so the orogeny process on the moon is very fast.
The moon looks very round, but there are not many mountains on it, and the peaks are very steep, these mountains are also named after the earth's mountains or people, the highest peak on the moon is located near the south pole of the moon, is the main peak of the Leibniz mountain range, the highest point is 9000 meters (compared to the average altitude of the Moon Sea Plain), is the highest mountain on the moon, more than 150 meters higher than Mount Everest on the earth (meters above sea level).

The Earth is 49 times the size of the Moon. The diameter of the Earth is 6,378 kilometers, and the Moon is 1,738 kilometers. The Earth is a multiple of the diameter of the Moon.
The mass of the Moon is approximately equal to 1 of the mass of the Earth. The average density of lunar matter is grams per cubic centimeter, which is equivalent to only 3 5 of the density of the Earth. The average distance between the Moon and the Earth is about 380,000 kilometers, which is about 30 times the diameter of the Earth.
Earth's gravitational pull.
It interacts with other objects in space, especially the Moon, which is the only natural satellite of the Earth. It takes about a few days for the Earth to revolve around the Sun. The Earth's axis of rotation is tilted relative to its orbital plane, thus producing seasons on Earth.
The gravitational interaction between the Earth and the Moon causes tides that stabilize the direction of the Earth on its axis and gradually slow down its rotation. Earth is the densest planet in the solar system and the largest and most massive of the four rocky planets.

The Earth is 49 times the size of the Moon. 。The diameter of the Earth is 6,378 kilometers, and the Moon is 1,738 kilometers. The moon is called the moon as seen by the human eye, and in ancient times, it was also called Taiyin, Xuantu, Chanjuan, and Yupan, which is 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 brief introduction to the origin of 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, but the theory supported by more factual evidence is that it was formed by the debris of a huge collision between the Earth and Theia, a celestial body the size of Mars, and gathered in the outer periphery of the Earth.
The front side of the moon is filled with huge impact craters filled with basalt lava flows ejected from dark volcanoes, forming a vast plain called the Moon Sea, which actually has not a drop of water in it.

From the large**, the diameter of the Earth is 12,740 kilometers, and the diameter of the Moon is 3,476 kilometers, and the Earth is twice the size of the Moon.
In terms of mass, the mass of the Earth is kilograms, the mass of the Moon is kilograms, and the Earth is twice that of the Moon.

The diameter of the Earth is 12,740 kilometers, and the diameter of the Moon is 3,476 kilometers, which is twice the size of the Moon.
The sun is fast, it is the sun that catches up with the moon. Judging from the solar eclipse, it is the moon that begins to obscure the sun from the west. In this case, it's simply to shade the sun from above.
41 inches is the standard size, and 40 inches is a little smaller. The 38-inch guitar can feel noticeably smaller. Under 36 inches, it is considered a travel guitar, and it is very easy to use. >>>More
Therefore, the earth is a scum ball, wandering by itself, regardless of the moon that has accompanied it for billions of years, the earth flies away, and the moon can only re-find the gravitational balance in the solar system and obtain a stable orbit.
There are 230 countries and territories in the world. According to the Population Branch of the United Nations Department of Economic and Social Information and Policy Analysis. In 2001, the world's total population was 6.1 billion. >>>More
The systematic scientific study of the question of the origin and evolution of the earth began in the middle of the eighteenth century, and several theories have been put forward to this day. The Earth, as a planet, is thought to have originated from the primordial solar nebula 4.6 billion years ago. Earth, like other planets, has undergone a number of common physical evolutionary processes, such as accretion and collision. >>>More
