In this article, let's open our minds and talk about Jupiter, the largest planet in the solar system. What will happen if it comes to earth?
Autumn 65438+ 10 is a good season to watch Jupiter. When the sun went down, Jupiter was already high in the southeast of the sky. When Venus falls, Jupiter is the brightest star in the sky. Jupiter is 630 million kilometers away from the earth, but it is still the second brightest star at night. This is because Jupiter is the king of planets in the solar system. It's very big.
Jupiter diameter 139822 km. What is this concept? The diameter of the earth is 12756 km. The diameter of Jupiter is 1 1 times that of the earth. Our earth is put on one by one like a string of candied haws, 1 1 a talent of the earth is worth a Jupiter. In terms of volume, Jupiter can hold more than 1300 Earth.
In addition, Jupiter is not only big, but also very massive. The mass of Jupiter is 3 18 times that of the earth. The other seven planets in the solar system add up to only 2/5 of Jupiter. Jupiter is the only planet in the solar system that can compete with the sun. Its mass is one thousandth of that of the sun. It makes the center of mass of the solar system fall at a distance of 47 thousand kilometers from the surface of the sun. This means that the sun is "shaken" because of Jupiter.
1July, 994 17, a comet named Shoemaker Levi -9 broke into Jupiter's territory. Under the strong gravity of Jupiter, this unlucky comet plunged into Jupiter and caused a powerful impact. This is equivalent to 2 billion atomic bombs exploding continuously over Jupiter. The event that the comet hit Jupiter made people realize that Jupiter saved the earth from the impact of many asteroids and comets from the outer solar system. Since then, Jupiter has become a famous god-the protector of the earth.
Are you thinking: wouldn't we feel more secure if Jupiter, as the protector of the earth, was closer to the earth? What will happen if Jupiter is put in the earth's orbit? What will happen to the earth?
The moon is a satellite of the earth. The moon is 3476 kilometers in diameter, ranking fifth in size among many satellites in the solar system. The average distance from the moon to the earth is 384,000 kilometers. If Jupiter is placed in the orbit of the moon, it will look closer to the earth than the moon. Because Jupiter's radius has reached 70 thousand kilometers. At that time, we may see such a scene on earth.
How big is Jupiter at this time? Its viewing angle has reached 20. The angle of view of the moon in the sky at full moon is 0.5. In this way, Jupiter's viewing angle is 40 times that of the full moon, and in terms of visible area, Jupiter is 1600 times larger than the full moon. Jupiter at this time, even in the daytime, we can see it clearly.
The yellow, white and brown stripes of those things on Jupiter turned out to be endless storms on Jupiter. The most shocking thing on Jupiter is the Great Red Spot Storm. It is about 25,000 kilometers long from east to west and12,000 kilometers wide from north to south. Can be discharged into two earths side by side From the earth, Jupiter looks like a cyclops staring at us.
Such a big Jupiter hanging in the sky has really brought us a strong visual impact, which is enough to shock our hearts.
So close to Jupiter, the earth has been tidal locking by Jupiter. One side of the earth will always face Jupiter. Just like the moon is always facing the earth. Looking at Jupiter from tidal locking Earth, Jupiter will not rise and fall in the west like the moon. It's like being frozen in the sky. People on the side of the earth facing away from Jupiter will never see Jupiter. Although I can't see it, I know in my heart that on the other side of the earth, there is a monster staring at the earth all the time.
1076, 39-year-old Su Shi was appointed as the magistrate of Mizhou. On the night of the full moon in Mid-Autumn Festival, Su Shi drank and enjoyed the moon until dawn, as drunk as a fiddler. The next day, Su Shi, who was still drunk, wrote this well-known song "When is there a bright moon in the water?"
Chanting about the moon is the most common way for ancient literati to express their feelings through scenery. However, if Su Shi had seen Jupiter in the orbit of the moon, it would not be so poetic anyway. Because Jupiter brings us not only visual shock, but also disaster.
We can refer to Jupiter's moon Io. Io is a planet slightly larger than the moon. Its distance to Jupiter is 420 thousand kilometers, which is very close to the distance from the moon to the earth. Io's orbit around Jupiter is an ellipse. Therefore, it will be close to Jupiter for a while and away from Jupiter for a while. In this way, under the repeated extrusion of Jupiter's tidal force, the magma inside Io frequently rushes out of the surface, forming a violent volcanic eruption. Io, a satellite slightly larger than the moon, has become the most active planet in the solar system.
This will happen to the earth when Jupiter is in the orbit of the moon. At this time, the earth is located outside the roche limit of Jupiter. It will not be torn off by Jupiter, but become one of its satellites. Jupiter's mighty tidal force ravaged the earth like Io. The Earth will also be deformed by the tearing of Jupiter's tidal force. This deformation will lead to earthquakes, volcanoes and tsunamis on the earth. These natural disasters must be preceded by the word "super". This is a terrible disaster for human beings and creatures on earth!
This is not all a disaster. As a giant planet in the solar system, if Jupiter is placed near the orbit of the moon, it will affect not only the earth, but the whole solar system. At this time, Jupiter is only 1 astronomical unit (1.500 million kilometers) away from the sun. The solar system is likely to reshuffle, because Jupiter is very close to the sun.
Fortunately, putting Jupiter in the moon's orbit is only a hypothesis, and it won't actually happen. We also use this question to open our minds and understand the power of Jupiter from another angle.
