The Earth orbits the Sun at a distance of 15 million kilometers from the Sun, and the Sun orbits the center of the Milky Way at a distance of 140 million kilometers from the Earth, eventually forming this magnificent solar system.
However, the entire system of the solar system is in a state of dynamic equilibrium, the reason for the formation is that each planet has its own gravitational attraction, and at the same time is attracted by the gravitational pull of the sun, and the planets have been moving around the sun in their respective orbits, so that the solar system is formed, and the celestial bodies in this system will also interact with each other, and it is possible that the orbit will change, resulting in the loss of the "stable" state of the system.
Many people are curious about the scene in the movie "The Wandering Earth", but in fact, in the next 1.2 million years, alien interstellar bodies will indeed cut a "wound" in the solar system, what will happen next?
1. The movement of the solar system.
There are eight planets in the solar system, several asteroids and five dwarf planets orbiting the sun, and there are many comets and small celestial bodies that pass through the solar system, and these small celestial bodies are likely to enter the solar system from the outer part of the solar system beyond Pluto's orbit in the Cooper belt or the Oort cloud, and a small number of small celestial bodies are drifting from outer space far away from the solar system.
Therefore, the small bodies in the solar system can be divided into two categories: the asteroids in the inner solar system and the asteroids floating in the outer solar system, although the number of these asteroids is not much compared to the huge objects in the solar system, but their total mass is a large number, so these small bodies may also have a certain impact on the orbits of various objects in the solar system.
Most of what we have learned before is about the solar system, for example, the sun moves around the center of the Milky Way, and the solar system will continue to advance in the process of moving around the center of the Milky Way, so the solar system is always moving, and in the process of moving in the solar system, you may encounter some Aomomo, which refers to those interstellar bodies that have not been observed and discovered in astronomy.
One study pointed out that a red dwarf star 0.3 light-years away from the Sun is also orbiting the center of the Milky Way, and the red dwarf may pass through the solar system when it moves according to its own orbit, causing some interference with the orbits of the planets in the solar system and even celestial bodies including the moon.
The red dwarf star is called Gliese 710, its mass is 1/3 times that of the Sun, so the gravitational pull of Gliese 710 is very obvious, and it is moving at a speed of 14 kilometers per second, and it is expected that it will be 2.3 light-years away from the Sun in 1.2 million years, but Gliese 710 is in the process of advancing due to its relatively small mass.
It will not have a large impact on the celestial bodies in the solar system, so it will not have any effect on the planets in the solar system, and if there are still Oort clouds in the solar system, the Oort cloud refers to a small group of comets and asteroids that exist in the extremely distant part of the solar system, and these asteroids will move around the sun due to the gravitational pull of the sun.
However, the small celestial bodies in the Oort cloud are affected by the gravitational pull of the planets, so the orbits between the planets are very unstable, so when Gliese 710 enters the Oort cloud in the solar system, it is very likely to have the largest range of effects, which will have an irregular gravitational pull on the celestial bodies in the solar system, resulting in the planets in the solar system not only converging towards the sun, but also the planets may be thrown out of the solar system.
2. Interference from alien interstellar bodies.
For the earth, if it is thrown out of the solar system, then the earth will leave the sun to be closer to other stars, the earth will no longer be irradiated by the sun, and the temperature will also drop significantly, not only that, the ocean will also be frozen at a lower temperature, and even frozen into a thick layer of ice in a very short time.
According to the research of scientists, if the ocean is frozen, then the ice that is still rich in oxygen cannot be photosynthesized because it does not shine sunlight, and the role of chloroplasts cannot be carried out, so oxygen will also be greatly reduced, and even due to the disappearance of the ocean, the earth's atmosphere can no longer be maintained, and gradually disappear in the extremely low temperature environment.
Then only a small amount of atmospheric matter will be left to sustain it, so people will lose their living environment, and they will have to look for springs deep underground to find a living environment, but these springs are also limited, and over time, human beings will eventually become extinct on the earth.
Therefore, when Gliese 710 comes, human beings will lose their original living environment, and only after the celestial bodies in the solar system have stabilized again, it is possible for the earth to have a similar environment again.
However, with the continuous progress of human science and technology, it is still 10,000 years before the earth is thrown out of the solar system, and many human beings have migrated from the earth to live on other planets outside the earth system.
Therefore, after the earth is thrown out of the solar system, human beings are no longer limited to the solar system as intelligent life, and human beings will continue to innovate in science and technology in the next 10,000 years, which is also expected to create an environment suitable for human beings outside the solar system in the future, which will also avoid the impact of alien interstellar bodies on the solar system.
3. Other impacts.
However, in the process of migration, in addition to the earth system, there are planetary systems composed of other extraterrestrial planets, which will also be disturbed by the external interstellar body Ao Momo, so in the process of migration, human beings also need to consider this aspect and choose a relatively stable outer solar system planetary system, which will also have a stronger guarantee for the survival of human beings in the later period.
In addition to the interstellar bodies moving around the sun, some of them are asteroids from the solar system, and the other part is a planet from outside the solar system that is affected by the sun's gravity.
The planet could be the most volcanically active object we've seen so far, and it could also be a small planet with extensive active glaciers, which also has the potential to attract human exploration.
At the same time, in the process of human exploration of the solar system, the sun will also be monitored and observed, so as to detect the outer solar system asteroids that enter the solar system as soon as possible, which will also provide time for human beings to take corresponding countermeasures and gradually get rid of the impact of extraterrestrial bodies on the solar system.
epilogue
Nowadays, the earth is the only home for human beings, so we also need to maintain the earth, not only that, but we also need to protect the biodiversity on the earth, the earth is the foundation of our human beings, so that life can continue to continue.
