Scientists have discovered the real "three-body" star, with an extremely complex and strange "disk".
The three-body star in Liu Cixin's science fiction works is a planet running around three stars, due to the impermanence of the three-body movement orbit, resulting in the planet shuttling back and forth between the three stars, cold and hot, the climate is also without any regular permanent era chaotic era alternate, so the trisolaran people have trained the strong survival ability of tardigrades dehydration and lozenges.
But scientists have not previously discovered such a star system in the real world, and even if the prototype Centauri in the novel α triad, the third star Proxima Centauri is at a position of 0.21 light-years — equivalent to 1/20 of its distance from our sun , orbiting the other two stars , and there is hardly any possibility of a trisolaran star orbiting these three stars at the same time.
But scientists may have recently discovered a real-world trisolaran, but this star system is still forming, which is about 1300 light-years away, in the constellation Orionis of the constellation orion.
The A and B stars of the GW Orionis galaxy orbit each other about an astronomical unit, that is, the distance between the Earth and the Sun; the C star orbits the two at a distance of 8 astronomical units, about a little closer than Saturn. Further outside is a vast disk of protoplanetarys, left over from the formation of these stars, which has not yet been completely blown away. Since the orbits of the three stars are not in one plane, the gravitational pull is extremely complex, and the shape of this disk is also very strange, which will definitely make you marvel.
The material in the disk can agglurate to form planets, and scientists recently discovered a gap in the disk that is thought to have formed a planet, clearing the orbit of other material. If confirmed, it would be the first known planet to orbit three stars, what we call a trisolaran.
Of course, it may be a little different from a trisolaran star, because the planet orbits three stars on the periphery, rather than shuttling between them. It is also unlikely that there will be any life on this trisolaran, nor is there any warm and habitable permanent epoch, because it is 100 astronomical units away from the three stars — in the solar system, even the farthest Pluto is only 40 astronomical units away from the sun, and it is already too cold to be cold. So this so-called three-body star is also a world with extremely weak sunlight, and it is difficult to imagine that there will be life.
If this triad does have a three-body star, what happens when you travel between these three stars?
I feel that there may really be a phenomenon of alternating between the permanent era and the chaotic era, as written in the novel. This is because the A star of this star system is 2.74 times the diameter of our Sun, the B star is 1.65 times, even the C star, there are 0.88 times, two are hotter than our sun, one is slightly colder, and the distance between them, respectively, is 1 astronomical unit and 8 astronomical units, you can analyze it a little, you know how this planet will suffer, it is definitely violent and hot, changeable.
But such a planet is almost impossible, because even if it did, it could quickly be swallowed up by one of these stars, or ejected from the system.
