What is the difference between the Moon and the Earth, and which is bigger the Moon or the Earth?

The moon is commonly known as the moon, also known as the sun yin. The age of the Moon is also about 4.6 billion years, and it is closely related to the Earth. The Moon also has a layered structure such as crust, mantle, and nucleus.

The Moon has a diameter of about 3476 kilometers and is 3 of the Earth's 11. The volume is only 1 49 of the earth, the mass is about 735 billion tons, which is equivalent to 1 81 of the mass of the earth, and the gravity of the moon is almost equivalent to 1 6 of the earth's gravity.

There are dark parts and bright areas above the Moon. There are craters dotted all over the place. The front of the Moon is always facing the Earth.

The gravitational pull exerted by the Moon on the Earth is one of the causes of tidal phenomena. The Moon's orbit around the Earth is a synchronous orbit, and the so-called synchronous rotation is not strict. Since the orbit of the Moon is elliptical, when the Moon is at perihelion, its rotation speed cannot catch up with the rotational speed, so we can see the area in the east of the Moon up to 98 degrees east longitude, on the contrary, when the Moon is at aphelion, the rotation speed is faster than the revolution speed, so we can see the area of the west of the Moon up to 98 degrees west longitude.

This phenomenon is called Libra motion. And because the moon's orbit is inclined to the earth's equator, when the moon moves in the starry sky, the polar region will shake by about 7 degrees, a phenomenon called libra motion. In addition, since the Moon is only 60 Earth radius from the Earth, if the observer observes from the moonrise to the moonset, the observation point will have a displacement of the Earth's diameter, and the area of the moon's longitude of 1 degree can be seen more often.

This phenomenon is called Libra motion.

The earth depends on water.

Secondly, the earth has an ozone layer.

Reducing the direct harm of solar radiation to the human body The earth has gravity that allows us to stand on our feet.

The moon is a wasteland.

There is no life, no interest. The temperature difference between day and night is extremely large

The Earth is larger than the Moon, with a kilometer radius of the Earth's equator and a radius of 1,738,000 meters at the Moon's equator.

Earth (English name: earth; Latin: Terra) is the third planet from the Sun and the only known celestial body that harbors and supports life.

Approximately the surface of the earth is a land mass made up of continents and islands. The remainder is covered by water, mostly by oceans, bays, and other saltwater bodies, but also by lakes, rivers, and other freshwaters, which together make up the hydrosphere.

Most of the Earth's polar regions are covered in ice. The Earth's outer layer is divided into several rigid tectonic plates that migrate to the surface over millions of years, while its interior remains active, with a solid iron core, a liquid outer core that generates the Earth's magnetic field, and a convective mantle that drives plate tectonics.

The Earth's atmosphere is mainly made up of nitrogen and oxygen. The tropics receive more solar energy than the polar regions and redistribute it through atmospheric and oceanic circulation. Greenhouse gases also play an important role in regulating the surface temperature.

The climate of a region is determined not only by latitude, but also by factors such as altitude and proximity to the mild ocean. Severe weather such as tropical cyclones, thunderstorms, and heat waves often occur in a wide area and have a great impact on life.

First, the sphere is different.

1. The Moon. The Moon is the fifth largest moon 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.

The average distance between the Moon and the Earth is about 38,440,000 kilometres, which is about 30 times the diameter of the Earth.

2. Earth. Earth is one of the eight planets in the solar system, the third planet in order of near and far from the sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, at a distance of 1.5 billion kilometers from the sun.

The Earth rotates from west to east while revolving around the Sun. It is 4,04.6 billion years old, and it has a natural satellite, the Moon, which forms a celestial system, the Earth-Moon System. It originated from the primordial solar nebula 4.6 billion years ago.

Second, the structural characteristics are different.

1. The Moon. From the propagation of lunar seismic waves, it is known that the moon also has a layered structure such as crust, mantle, and nucleus. The average thickness of the outermost lunar crust is about 60 64 7 km. Below the lunar crust to a depth of 1,000 km is the lunar mantle, which occupies most of the moon's volume.

Below the mantle is the lunar core, which has a temperature of about 1000 to 1500, so it is likely to be in a molten state, and it is probably composed of Fe Ni S and garerite material.

2. Earth. The geosphere is divided into two parts: the outer and inner spheres of the earth. The Earth's outer sphere can be further divided into four fundamental layers, namely the atmosphere, hydrosphere, biosphere, and lithosphere; The Earth's inner sphere can be further divided into three fundamental spheres, namely the mantle sphere, the outer nuclear liquid sphere, and the solid inner core.

In addition, there is an asthenosphere between the outer and inner spheres of the Earth, which is a transition layer between the outer and inner spheres of the Earth, located at an average depth of about 150 kilometers below the surface. In this way, the entire Earth consists of a total of eight spheres, in which the lithosphere, asthenosphere and inner sphere together constitute the so-called solid Earth.

Third, the revolution is different.

1. The Moon. 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.

Cycle 27 to 32 days. The average inclination of the lunar orbit (white path) to the Earth's orbit (ecliptic) is 5°09'. But it is known that the Moon is gradually departing from the Earth at an average annual rate of 3 8cm.

2. Earth. The orbit of the Earth's revolution is elliptical, the semi-major diameter of the orbit is 149597870 km, the eccentricity of the orbit is 0 0167, and the average orbital velocity of the revolution is 29 79 km per second. The angle between the orbital plane (ecliptic plane) and the Earth's equatorial plane is 23°27', which is called the yellow-ecliptic angle.

The temperature of the same place on the Moon varies greatly, the Earth is the planet of the Sun, and the Moon is a satellite of the Earth.

First of all, the month bai

There is no air on the ball. And the earth duë on zhi

There is air, there is no atmosphere on the moon, but the earth has a powerful atmosphere, there is no grass on the moon, but the earth is full of plants, the moon cannot live people, but the earth can live people. In the morning, the temperature of the moon can reach 160 °C. And the temperature at night can reach minus 180.

The Earth is the planet, and the Moon is the Guardian.

The gravitational pull of the Earth is comparatively large and the gravitational pull of the Moon is very small.

There are living things on Earth, there are no living things on the Moon.

The Earth has an atmosphere and the atmosphere of the Moon is very, very thin.

The temperature difference between day and night on Earth is small, and the temperature difference between day and night on the Moon is particularly large.

The most essential difference is that the Earth is a planet.

And the moon is the only moon of the earth.

The earth has an ecological environment where humans and creatures can live; The moon does not.

There is no air on the Moon, there is air on Earth.

21 The Earth is a planet and the Moon is a satellite.

The difference between the Earth and the Moon is that the size is different, the temperature of the same place on the Moon varies greatly, the Earth is the planet of the Sun, and the Moon is the satellite of the Earth; The similarity is that they are all celestial bodies, none of which can emit light by themselves, and in the same solar system, there are mountains and plains on the surface.

Earth is one of the eight planets in the solar system, the third planet in order from near to far, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun.

1.Gravitational force is different, the gravitational force on the Moon is one-sixth of that on Earth;

2.The moon has no air, no water, no living organisms, and no atmosphere, so it is a wild ball, while the earth has an atmosphere of air and water life. It's a planet fit for human life.

3.The ultraviolet rays that the sun shines on the moon cannot be disturbed, while there is an atmosphere on the earth that can interfere.

4.The Moon is a satellite of the Earth, while the Earth is a satellite of the Sun.

The Moon is a satellite of the Earth.

A satellite is a natural or man-made object that orbits a planet, and the Moon is the most obvious example. In the solar system, except for Mercury and Venus, all other planets have natural satellites. The total number of known natural satellites (not counting the fragments that make up the planetary rings) is at least 40, with Saturn having the most natural satellites.

The Moon is the only natural satellite of the Earth, probably formed about 4.5 billion years ago, and shortly after the formation of the Earth's Vision, there are several hypotheses about its origin, and the theory supported by more factual evidence is that it formed from 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 to form the "Great Collision Origin Theory".

Topography of the Moon:

The surface of the moon has dark parts and bright areas, the bright areas are highlands, and the dark areas are low-lying areas such as plains or basins, which are called lunar lands and moon-seas, respectively. When early astronomers looked at the Moon, they thought that the dark areas were covered with seawater, so they called them "seas". The famous ones are the sea of clouds, the wet sea, the still sea, etc.

The bright part is the mountains, which are dotted with craters, or impact craters, which are low-lying forms of annular uplift. There are more than 33,000 craters on the moon with a diameter of more than 1,000 meters.

The Bailey crater, located near Antarctica, is 295 kilometers in diameter and could fit the entire island of Hainan. The deepest is the Newton crater, which is 8,788 meters deep. In addition to the craters that hit the town, there are also ordinary mountains on the moon. Mountains and deep valleys are stacked on top of each other, creating a unique scenery.
