What planets in the solar system have water?

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.

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.

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.

1. Europa.

Europa's surface temperature averages 110 K (minus 163) in the equatorial region, low at both poles, and only 50 K (minus 223), so the surface water is permanently frozen. But the heat provided by tidal forces may keep the water below the surface ice water.

This speculation was initially the result of a series of speculations about tidal heat (slightly eccentric orbits and the orbital resonances between Europa and other Galilean moons).

2. Enceladus.

In 2008, scientists observed water vapor ejecting from the surface of Enceladus. This observation proves the presence of liquid water on the satellite and supports the idea that life is possible on Enceladus.

3. Triton.

Triton's geological activity and possible internal heat make it a liquid water layer inside. The presence of antifreeze agents such as ammonia increases the likelihood of liquid water. It is possible that primitive life could exist in such an underground ocean.

4. Mercury. Radar observations carried out in 1992 showed that Mercury's North Pole was wide with ice. It is believed that this ice exists at the bottom of the crater, where sunlight can never reach early, and accumulates due to comet impacts or gases from the planet's interior coming out of the surface.

5. Earth. The interior of the earth has a core, mantle, and crust structure, and the outside of the earth has a hydrosphere, atmosphere, and magnetic field. The Earth is the only celestial body in the universe where life is known to exist, and it is home to millions of living beings, including humans.

As follows:

1. Liquid methane ocean over Titan.

Titan is the second largest moon in the solar system, and large amounts of liquid methane are present on this moon. In some theory, this organic matter is enough to sustain some life, and the volume of liquid methane oceans on Titan is even comparable to that of Earth's oceans.

2. The hydrothermal ocean beneath Enceladus.

There is an ocean on Enceladus, and the temperature of the ocean is very high. Because there are one or more fixed-point heat sources on Enceladus, a special substance is formed in this ice body of only 500 km: silica.

3. Pluto and its moon Charon.

Pluto is a planet very far from the Sun, and because of its special orbit that led to its removal from the solar system, Pluto's surface is very cold. There are rifts in Pluto and its moons, and these rifts indicate that there was once a water source or that there was water flowing underground.

How did water come from in the universe?

If you want to get water, you first need hydrogen and oxygen, of which hydrogen can be said to be "everywhere" in the universe, because the hydrogen atom is actually composed of a proton and an electron, and the structure is very simple, so not long after the birth of the universe, hydrogen has existed in large quantities.

The emergence of oxygen needs to be "processed" by nuclear fusion inside the star. After the death of the star, these oxygen elements are released into space, and the next thing is that the hydrogen and oxygen elements in the universe are chemically reacted to form water molecules (H2O).

I believe everyone knows that the planets of the solar system have their own names, such as Mercury, Venus, Mars, etc. But instead of Mercury being rich in water, is Mars hot and dry? This is not the case.

Mercury does not have an abundant water resource. Mercury is very close to the Sun and has a high temperature, and even if there is water, it will evaporate in a short time, so scientists have not found that Mercury has liquid water. But scientists have found solid ice in Mercury's Arctic crater, but in small quantities.

The situation in Jinxing is similar to that of Mercury, where only trace water resources exist.

Mars is the most suitable planet for human migration in the solar system, and its planetary surface is naturally very rich in water resources. Scientists have discovered liquid lakes beneath the surface in the South Pole region of Mars. Jupiter and Saturn, which are bulky, also have abundant water resources.

Neptune and Pluto are too far apart and the temperature is low. Thus, on both Neptune and Pluto, the water resources form ice, which exists in solid form. In addition to water, there are substances in the form of ice such as methane and ammonia.

The water content of the planets of the solar system has a lot to do with the distance from the sun. The distance is too close, the temperature is very high, and most of the moisture cannot be present. Where does the solar system's water come from?

Scientists speculate that this may be related to the Oort cloud at the boundary of the solar system and the Kuiper Belt planetary belt, which is rich in glaciers.

The comets we see on Earth come from a comet warehouse called the Kuiper Belt, so why should there be a Kuiper Belt to form a comet? If the celestial volatile matter (mostly water ice) in the asteroid's orbit has been sublimated (roasted) in the sun, then the comet that passes through the "snow line" will only be exposed to sunlight when it enters Saturn's orbit, exposing the comet material to sunlight. Dust tails and ion tails are formed, becoming comets that we can see (otherwise the comet magnitude would be too low.

Then we can imagine that there are also so many comets that can be the material of the planets that could be formed by the dust disk in the early days of the solar system. But the conditions are different, and there are also ways in which compounds exist in the planet formation process, and when the early planets cleaned the dust disk, even if the asteroid encountered high temperatures, it would not retain this moisture, and the Earth's gravity was moderate, and the temperature was also moderate. After formation, during the orbital cleanup, the asteroid encounters high temperatures, and this moisture arrives.

In the billions of years of Earth's history, hundreds of thousands of tons of comet material have hit the atmosphere every year, which is also an accumulation process!

Basically made of elements, some chemical reactions can also form water. Because there are no conditions for generation on other planets, it is either too hot or too cold.

Because the earth's crust changes, and then the formation of a kind of water, is such a principle, and then there is the water that extends from the cracks in the earth, like the solar system and the planets do not have this special kind of natural change.

There is a lot of speculation about water, the most common one now is that it is brought by meteorites from outer space and landed on Earth, while other planets such as Mars are too close to the Sun, causing solar flares to erupt and evaporate, the atmosphere on Mars causes moisture to disperse, and Jupiter is a huge gas planet that also does not contain water.

Because Mercury is small, full of water resources, and closest to the Sun, Mercury has always been considered by humans to be a special planet among the eight planets in the solar system.

Mainly because Mercury is the closest planet to the Sun has a lot of secrets that people are going to do. We found that Mercury is closest to the Sun, and that the planet is relatively dry and has no water, mainly because it is hidden from the sun.

Mercury does not have moons, so there is no concept of a "moon" there. Mercury's axis of rotation is almost perpendicular to its orbital plane, so there are no seasons of latitude on Mercury. Since Mercury always faces the Sun at perihelion and at aphelion at a longitude 90° apart, there is a seasonal change with different longitudes, which is also a great spectacle in the solar system.
