Is Saturn suitable for human habitation?

Question 1: Can Saturn and Mars be suitable for human habitation? Why is Saturn definitely not? Saturn is a gaseous planet. Although its center has a rock core with a diameter of 20,000 kilometers, outside the core is Saturn's atmosphere with a thickness of 60,000 kilometers. Moreover, Saturn's atmosphere is 96.3% hydrogen and 3.25% helium, with a very small amount of ammonia, acetylene, ethane, phosphine and methane. There is still a strong wind on Saturn, and the wind speed is as high as1800 km/h. How can people live in such a place?

Mars is called a smaller earth. There used to be water on the surface of Mars, and the temperature was as high as 25 degrees Celsius, 24 hours a day. But at least, Mars is not suitable for human habitation. First, Mars is too dry and there is no water. Second, the mass of Mars is only one tenth of that of the Earth. The mass is too small, which makes the atmosphere of Mars too thin. The density of the atmosphere is less than 1% of that of the earth, and the main component is carbon dioxide. Oxygen is only 65438+ 0.5 per thousand, so humans can't live on the surface of Mars.

Maybe one day, humans will put an asteroid made of water on Mars, so that Mars can form an ocean again, and then the atmosphere will become thicker and the air pressure will increase, and then plants will be transplanted from the earth to Mars, changing the composition of the Martian atmosphere and producing more oxygen. Maybe one day, humans can move to Mars.

Question 2: Is Saturn suitable for human habitation? Because Saturn has no soil ... it can't grow crops ... it will starve to death.

Question 3: Why are Saturn and the moon unfit for human habitation without oxygen?

Question 4: Which of the eight planets is more suitable for human habitation? If we insist on Mars, the water and temperature of Venus are too high for human beings to adapt. Jupiter and Saturn, two giant planets, belong to gaseous planets. Let's start with Jupiter Jupiter is mainly composed of hydrogen and helium, and the temperature of bile in the middle is estimated to be as high as 30500℃. Jupiter's surface consists of liquid hydrogen and helium. Deep into the center of the earth, it is liquid metal hydrogen, and the core is rock core, which is about twice as big and ten times as heavy as the earth. So no human can stay on the mainland. Saturn and Jupiter have similar surfaces. For the remaining distant planet Uranus Neptune, the light and temperature are not good. However, we can also consider the satellites of some planets, which may be possible. But at present, compared with the environment of the earth, the environment of other planets is much worse. So let's protect our earth.

Question 8: What are the planets suitable for human habitation, and can humans reach Kepler -22b?

Kepler -22b is the first exoplanet located in the livable zone confirmed by NASA in February, 201/. It revolves around a star very similar to the sun. NASA confirmed that Kepler -22b planet is suitable for human habitation.

Edit this paragraph to discover planets.

Kepler mission of NASA confirmed the first of the so-called "Yi" in 20112.

Comparison of Kepler -22b planetary system and planets of the solar system.

An exoplanet in the habitable zone, orbiting a star very similar to our sun. The newly confirmed exoplanet is named -22b (Kepler -22b. As of February 2 0 1 1, scientists reported that 54 exoplanet candidates had been discovered in the livable zone, of which Kepler -22b was the first one to be confirmed.

William? Brouqui is a scientist at the Ames Research Center of NASA in California and the chief scientist of the Kepler telescope project. He led the discovery of Kepler -22b. He said: "The first time we observed the possible sporadic clues of this exoplanet, it was only three days after the completion of the telescope's launch and debugging work, and we finally observed the repeated Ling Xing phenomenon three times during the holiday of 20 10, so we can confirm this discovery."

Edit the introduction of this planet.

Kepler -22b is about 2.4 times the diameter of the earth and about 600 light years away. Using the existing spacecraft, it will take 22 million years for human beings to fly to Kepler -22b. Although its diameter is much larger than that of the earth, its orbital period is about 290 days, which is not much different from that of the earth. The central star it surrounds is very similar to the sun, and it is also a yellow dwarf with spectral type G, but its mass is slightly smaller. The surface temperature of this planet is about 70 degrees Fahrenheit (equivalent to 2 1 celsius), which is very suitable for living.

However, scientists are not sure whether the earth's surface is rock, liquid or gas. However, this discovery has taken a solid step towards the ultimate goal of finding another earth. [ 1]

Composition and structure

So far, its exact quality and surface composition are still unknown. If its density is equivalent to that of the earth (5.5 15 g/cm), its mass may be 13.8 (2.4) times that of the earth [calc 1], and its surface gravity is 2.4 times that of the earth [calc 2]. If its density is equivalent to liquid water (1 g/cm), its mass is 2.5 times that of the earth [calc 3] and its surface gravity is 0.43 times that of the earth [calc 4]. This planet may be classified as a super earth, but it depends on its actual mass.

Initially, it was estimated that the mass of this planet may reach 35 times that of the Earth, which is similar to Neptune's gas giant planet, but the most likely situation is that it is an ocean planet, and its mass is 10 times that of the Earth.

According to its actual mass, the planet may be super earth or "warm Neptune".

Edit this immigration conjecture

However, it is unrealistic to emigrate immediately, because Kepler-22b is located in the direction of Lyra and Cygnus, about 600 light years away from the earth. Previously, scientists have discovered many planets in the "livable zone", but unfortunately, most of them are huge gas planets, which are not suitable for life. Kepler-22b is not much bigger than the earth, which means it is likely to be made of rocks, but scientists have not confirmed whether the planet is mainly made of rocks or gases or liquids. This is the planet that has proved to be the closest to the shape of the earth in size and orbit.

Edit this paragraph as its "sun": slightly smaller and slightly colder.

The parent star around this planet is slightly smaller and colder than the sun, but it belongs to a relatively stable and long-lived star like the sun. Douglas, a scientist on the Kepler project at NASA headquarters, said that the discovery of Kepler -22b was "an important milestone in the process of discovering our twin brothers on earth".
