How scary is Jupiter? The internal environment is quite scary, just one storm can drop 3 earths
Jupiter, a planet with constant storms, even some storms, for hundreds of years. If you put these storms on the earth, that can directly tear the earth to shreds. Jupiter, the largest planet in the solar system, takes Jupiter's most typical storm, the Great Red Spot, for example. It can hold 3 Earths. Throw in the four rocky planets Mercury, Venus, Earth, and Mars, and the Great Red Spot can be swallowed. Even more frightening is that Jupiter has no ground, and if you go deep into it, you will come into direct contact with Jupiter's core. Such a terrifying Jupiter is a "heart-warming" big brother who has blocked countless impacts for the four planets including the earth. Jupiter's Great Red SpotSuper planet
How big is Jupiter, let's put it this way, 99.99% of the mass of the solar system is occupied by the sun, and in the remaining 0.01%, Jupiter is again Dominated the eight buckets. The remaining seven planets add up to the size and mass of Jupiter, which can be described as the first "big brother" of the solar system. However, such a large Jupiter is a "fancy" planet because it has no land and is a "big balloon". Jupiter is a gaseous planet, and the probe reaching Jupiter cannot be called a landing, because there is no "land". It has an iron core, which is much larger than the earth, and the magnetic field strength is more than 10 times that of the earth. The temperature of this core exceeds 7000 ℃. Outside of Jupiter's structural core, it is surrounded by dense gas. We can call the gas that composes Jupiter its atmosphere, so Jupiter is the planet with the thickest atmosphere in the solar system. Many of Jupiter's atmospheres are flammable gases, such as hydrogen, methane, ethane, etc. These gases are orange-red when illuminated by sunlight, a real big fat orange. And this big orange has a very bad temper. There are storms going on all the time, and the biggest storm is the Great Red Spot. Jupiter is the big fat orange among planets. We often say on Earth that wind and rain come and go quickly. This sentence is not easy to say on Jupiter, because the Great Red Spot has lasted for at least 300 years and has formed its own cycle. . The large storm spans 24,000 to 40,000 kilometers from east to west, and 12,000 to 14,000 kilometers from north to south. The direction of rotation is counterclockwise, and the rotation period is 6 Earth days, which is equivalent to 14 Jupiter days. What is even more amazing is that the color of the Great Red Spot will change, most of the time it is orange-red, but also yellow and orange. In addition to the Great Red Spot, Jupiter also has many small red spots, small orange spots, small yellow spots, etc. These are all storms. The Great Red Spot is actually a storm, so there is nothing to worry about. Jupiter has a lot of anger and long spots on the surface. Just throwing a Jupiter storm on the earth is a disaster that destroys the world. If it is the Great Red Spot, it is estimated that 3 earths are not enough for it to blow. Not only the earth, but throw all the four rocky planets in the solar system into it, and the Great Red Spot can laugh at them and tear them apart. The internal environment of Jupiter is so terrifying, it has been a storm for 4.6 billion years! Why is Jupiter, a planet that is also the sun, so big? Comparison of Jupiter and other planetsJupiter's past and present
The solar system was born in a chaotic nebula, and Jupiter is likely to be a star without climate. Jupiter is very large compared to other planets, but it is still far from the smallest star Jupiter. The smallest star found so far is 2MASS J0523-1403, which is 77 times the mass of Jupiter. So astronomers believe that 77 times Jupiter is a limit. If an initial star cannot meet such a mass requirement, then it is likely to fail to "ignite" and can only become a planet. The smallest star and the sun About 4.6 billion years ago, the solar system was born out of a nebula. Jupiter was still brewing and developing in the direction of the star, but it was a pity that it encountered a more powerful sun. The gravitational pull of the sun's mass forcibly interrupted Jupiter's path to becoming a star, binding it into orbit. This can also be a good explanation, the main composition of Jupiter's gas is very close to that of the sun. However, Jupiter is still a long way from becoming a real star, and it cannot be done by simply "igniting" it. Jupiter is still a long way from the star. As mentioned earlier, the minimum standard for a star is 77 Jupiter's mass, and Jupiter is 76 away from becoming a star. If Jupiter is "ignited" now, there may only be a big explosion in the solar system, and the energy of the explosion may affect the motion of the other seven planets, but has no effect on the sun. The mass of Jupiter is too great, the solar system will be greatly changed without it, and even the pattern will be changed. After all, Jupiter once dominated the fate of a planet in the solar system. There is a "gravel region" in the solar system called the asteroid belt, which is between Mars and Jupiter. There are more than 500,000 years of large and small asteroids distributed in it. Their predecessor was an unformed planet. The gravitational pull of Jupiter in the asteroid belt hindered the formation of this planet, and it ended up in pieces, and the asteroid belt is its remnant. This is not over yet, the unborn planet, and part of it was captured by Jupiter's gravity and became a satellite of Jupiter. If Jupiter was bigger when the solar system was formed, it is estimated that Mars would also be doomed, either joining the asteroid belt, or directly becoming a satellite of Jupiter with the small body of Mars. In this way, Jupiter is an "evil star", which directly "aborts" a planet in the solar system. However, Jupiter's huge gravitational force protects the four planets in the asteroid belt to some extent, and the earth is also its beneficiary. The asteroid belt's predecessor was the unformed planet reliable "big brother"
In 1994, a comet crashed into Jupiter, the closest The most recent comet impact on Earth. Although Jupiter has no land, its gas was still smashed into many large craters by the comet, because it was torn into more than 20 pieces after entering Jupiter's atmosphere, and finally 4 impact craters were more than 10,000 kilometers in diameter. The diameter of the earth is only 12,756 kilometers, which means that the fragments of these comets collide together and the earth is gone. If it wasn't for Jupiter's gravitational pull on the comet, it might have come to Earth. The time of the comet impact should be known about 66 million years ago, when the earth was hit by an asteroid with a diameter of about 10 kilometers. The result was really bad, and it directly set off a round of mass extinction. If the Earth was constantly in such a state of impact, the evolution of life would not be what it is today. Perhaps an impact will directly wipe out life on Earth, or even make the Earth cease to exist. In addition to the earth, there are also Mercury, Venus and Mars, which should say to Jupiter: listen to me, thank you, because of you, we will not be hit. Mars should also say: Thank you for not growing so big, otherwise I would be gone. The Four Rocky Planets of the Solar SystemExploring Jupiter
Humans have been exploring Jupiter for a long time. Jupiter and some of its moons have been discovered since the time of Galileo. . Jupiter is not too close to the earth but not too far away, so there are not many probes that have observed Jupiter. The first man-made probe to observe Jupiter was Pioneer 10. Later, Voyager 1 and 2 also observed Jupiter by the way because they wanted to use Jupiter's gravitational slingshot. The Galileo and Juno probes that were launched later were dedicated to detecting Jupiter and its moons. The Galileo probe Jupiter is a gaseous planet, so the probe has no way to log it. Regarding the existence of life on Jupiter, most opinions believe that Jupiter does not exist. But a small number of astronomers also believe that Jupiter has colloidal organisms that roam Jupiter's atmosphere like fish in water. Jupiter is less likely to have life, but it has two moons that have a high probability of life, Europa and Ganymede. There are 79 Jupiter moons that have been identified by mankind. Among them, Europa is the most famous. The Voyager series probes used precious energy to fly to see it. Jupiter's surface is imagined to be a completely frozen planet, covered by a 100-kilometer-thick layer of ice, which is likely to be an ocean below. Europa was photographed with geysers, suggesting that there are still craters in the ocean beneath the ice, and these conditions are very similar to those on early Earth. Various conditions indicate that Europa is not a simple moon, and its younger brother Ganymede is similar to it, and it is larger and has a magnetic field. In order to gain a deeper understanding of Europa, NASA is preparing to launch the "Europa Clipper" in cooperation with ESA, which is dedicated to exploring Europa. Jupiter Europa will also become another satellite that human beings dream about after the moon.
