Mercury is the smallest of the eight planets in the solar system, that is, the last and eighth.

Hope it helps.

Mercury is closest to the Sun in terms of distance from the Sun.

In terms of mass, Mercury is the smallest (Pluto is actually smaller, but two years ago, Pluto was judged by the International Astronomical Society to be a small body in the Coibo belt, not a big planet, so the honor of smallest planet was returned to Mercury).

Rotation and revolution are the first, distance is the first, and mass is the eighth (in descending order).

Distance is the first, running speed is the first, and quality is the eighth.

Life eventually came into existence on the earth because of water, and it was in the solar system.

The water content of the earth is relatively small, and the moons of Jupiter and Saturn contain much more water than the earth. There are eight planets in the solar system.

There are at least 173 moons, 5 dwarf planets, and countless small objects. Structurally, the eight planets occupy the main orbital position, the outermost planet, Pluto.

It also has an orbital radius of 39 astronomical units, so from Pluto's orbit as the boundary, it is basically in the orbit of the outer solar system.

At the center of the solar system is a huge sun, and the eight large planets and the dwarf planet Pluto all revolve around the sun in their respective elliptical orbits. The distance between the planets and the planets feels so close. This gives us the impression that the solar system is not very big.

Watery regions of the solar system: Saturn's rings, asteroid belt, Kuiper belt. There is no conclusive conclusion on the ** of water on the earth, but it is said that it was brought by the impact of a comet originating in the Kuiper Belt when it hit the earth, and the impact caused the ice on the comet to evaporate rapidly and then gradually captured by the earth's gravity, forming rain falling on the ground, producing rivers, lakes and seas.

Saturn's rings, Jupiter's rings, asteroid belts, and Kuiper belts contain ice fragments, meteorite fragments, etc., and the total amount may far exceed that of Earth.

Watery planet: Europa.

Ilymede. 3. Ganymede.

4. Ceres.

Pluto, Enceladus. Europa and Enceladus, in particular, contain more than several times as much water as the Earth. Europa is only a quarter of the diameter of the Earth, but it has an ice layer about 100 kilometers thick, and all the water gathers into a sphere, which will reach a diameter of 877 kilometers; Enceladus has been confirmed to have water by the Cassini probe, but beneath the surface ice sheet is an ocean of liquid water, estimated to contain 2-3 times more water than Earth.

Water is not a very scarce thing in the solar system and even in the universe, and in recent years the moon has been.

Mars has also been confirmed to contain a certain amount of water. Water on Earth is related to the origin of life and also to mass fraction.

Larger phosphorus, which is produced in supernova explosions, is not guaranteed to be captured by the planet and is involved in the origin and evolution of life.

Regardless of the form in which water exists, then most of the celestial bodies in the solar system have water. For example, the Sun, Mercury, Earth, Mars, ......

Neptune is surrounded by liquid water, Mars may have water in the form of ice, Uranus has ice on the surface, which is considered water in the form of ice, and Pluto has gaseous water on it.

NASA's Curiosity rover has discovered water forms on Mars. Most planets have water forms, only Earth has liquid water.

Of the eight planets in the solar system, Mercury is the smallest of them.

According to scientists' theories, Mercury has now lost its mantle, leaving only an iron core.

The second reason is that Venus is located in a very dense atmosphere, and the main component of the atmosphere is carbon dioxide, so Venus is very reflective, but the light reflected to the solar system is stronger, and the other reason is that Venus is very close to the Earth.

At its closest point to Earth, Venus is 40.5 million kilometers away, 100 times the distance between the Earth and the Moon.

So, is Venus the closest planet to Earth?

In this case, why do scientists consider Mercury to be closest to Earth? In astronomy, the closest distance between planets is when two planets are on the same side of the Sun, and the closest distance between Venus and the Earth is 40.5 million kilometers.

However, with the continuous progress of human technology, we have also learned some secrets of Mercury through probes, and the more we understand, the more we find that Mercury is not as simple as we think.

The presence of liquid water on the surface of the planet is important for the birth of life.

Mercury is the closest to the Sun and is the smallest of the eight planets.

Given that Mercury and Venus are too close to the Sun, planetary temperatures will rise very high.

The average distance from the Earth to the Sun is 100 million kilometers, 41 million kilometers farther than Venus and 55 million kilometers closer than Mars.

In fact, the mass of the Earth is just right enough to produce a strong magnetic field and a thick enough atmosphere to protect the Earth's water. In addition, the distance from the earth to the sun is just right enough for water to form an ocean and exist on the surface.

According to the Great Migration Hypothesis, Jupiter was first formed at a distance of about 100 million kilometers from the Sun's astronomical unit (about 100 million kilometers) millions of years after the formation of the Sun.

Mercury itself is relatively small, and the distance from the earth is also very far, it generally appears at dawn or evening, because the sky is still relatively bright at this time, so people on the earth with the naked eye may see it very small, generally want to observe Mercury, but also need to use professional equipment.

The solar system is a small celestial system in the Milky Way, and many planets have similar characteristics. Therefore, here humans are constantly looking for companions and looking for the presence of life. However, the conditions under which life exists are very unique. On these balls, we don't even see the presence of water.

Well, that's all for you in this issue, and the next issue will introduce you to Venus, one of the eight planets.

Among the planets in the solar system, Earth is the only planet known to have a large amount of liquid water. With the exception of Earth, water on other planets is limited or non-existent. However, water may be present on some planets' letter moons or terrestrial planets.

For example, Jupiter's moons Europa and Enceladus, as well as Saturn's moon ice giant Enceladus, are believed to have oceans of liquid water beneath their ice. In addition, water ice may exist in the polar regions and subsurface on Mars. In the course of scientific research and exploration, we are also studying the water resources of other planets and moons in the solar system.

In the solar system, Earth is the only planet known to have a large amount of liquid water. Water on Earth exists in liquid, solid (ice), and gaseous (water vapor) forms, making up the Earth's water bodies such as oceans, lakes, rivers, and groundwater.

Water is also present on other planets, but they have relatively little water or in the form of ice compared to water on Earth. Here are some of the presence of water on other planets in the solar system:

Mars: There is ice on Mars, especially in the polar regions of the North and South Poles, which contain water ice and carbon dioxide ice. In addition, the Martian atmosphere also contains a certain amount of hydrovapor gas.

Jupiter: Jupiter is a giant gaseous planet that has water vapor in its atmosphere, but water exists in Jupiter's gaseous state due to extreme high pressure and temperature conditions.

Saturn: Saturn is also a gas planet, similar to Jupiter, and it also contains water vapor in its atmosphere.

Venus: The surface of Venus is extremely hot, and its atmosphere contains a small amount of water vapor, but due to extreme temperatures and pressures, water cannot exist in a liquid state on the surface of Venus.

Mercury: Despite Mercury's extremely high and low surface temperatures, scientists speculate that water ice may be present in its polar regions.

In addition to planets, evidence of the presence of water has also been found on some moons in the solar system (closed or called the Moon), such as Jupiter's Europa moons and Titan, and Saturn's Titan. The water on these satellites is mainly in the form of ice in the subterranean ice below the surface. These findings have also stimulated interest and research into whether there was pre-ligated life on other celestial bodies in the solar system.

In the early solar system, it is likely that many planetary cores will form at the same time near the same planetary orbit. These planetary cores collided. Mercury also has the ability to be the result of multiple planetary embryos colliding with each other.

In the collision, Mercury was stripped of its surface material, changed its orbit, flew towards the Sun, and stabilized at its closest place. The reason Mercury does not have moons is that it is very close to the Sun. The moons of the Forechamber Planet either fly towards the Sun or fall to the surface of Mercury.

Mercury has an atmosphere, volcanoes, magnetic fields, and water ice. Mercury has a solid-state inner core several kilometers in diameter, surrounded by a liquid outer core more than 1,000 meters thick. This liquid outer core causes Mercury to produce a magnetic field.

Humans launch the Human Messenger probe to Mercury. After measurement, the mass of Mercury is 330 billion tons. The diameter of Mercury is 4879 kilometers.

After Mercury formed in its early days, it was hit by other planets. Mercury's orbit was deflected by the impact. It is possible that Mercury was born hundreds of millions of kilometers from the Sun. This place is right between the orbits of the Sun and Mars.

Closest to the Sun in order of farther away: Mercury,

Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

The realm of the solar system includes the Sun, four Earth-like inner planets, an asteroid belt made up of many small rocks, four huge outer planets filled with gas, and a second small celestial body region filled with small frozen rocks known as the Kuiper Belt. Among them, there are currently eight planets in the solar system, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The orbits of the major celestial bodies in the solar system are in the vicinity of the plane of the Earth's orbit around the Sun (ecliptic). The planets are all very close to the ecliptic, and comets and Kuiper Belt objects usually have a more pronounced tilt.

A bird's-eye view of the solar system from the north, all the planets and most of the other celestial bodies orbit the Sun in a counterclockwise (left-handed) direction. There are some exceptions, such as Halley's Comet.

Celestial bodies orbiting the Sun obey Kepler's laws of planetary motion, and their orbits are all an ellipse focused on the Sun, and the closer they get to the Sun, the faster they are. The orbit of the planet is nearly circular.

In such a vast space, there are many ways to represent the distance of each orbit in the solar system. In fact, the farther away from the Sun the planet or ring.

Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

There is an asteroid belt between Earth and Mars, and there is Pluto after Neptune, which is no longer a big planet, and there is the Kuiper Belt outside Pluto, which is the home of the comet.

The planets in the solar system are, in descending order from closest to the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, Little Pluto, Ice Dwarf, DH-like Quasar, Sedna.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The Earth has 1,333 cubic kilometers of water, which is not the largest amount of water on our planet compared to other planets in the solar system.

Scientists say (I don't know if it's accurate) that Europa, a moon of Jupiter, is about the size of our moon and may be hiding a subsurface ocean that is more than twice as large as Earth's. Europa, on the other hand, has more than 30 times the amount of liquid and solid water on Earth. It's likely that Titan, a small moon of Saturn, also has a subsurface ocean.

Planets in the solar system are sorted by the amount of water they haveFrom less to moreIn order: Titan, Titan, Earth, Europa, Pluto, Trilad, Calmede, Titan, and Callisto.
