What does the tria system look like? Why does this phenomenon occur?

In theory, it is in a void situation, and it is very easy to be subject to minor hazards causing road and rail production.Unprecedented changes have led to the fact that there will be no fixed solution to the three-body problem. Only when the mass of the three stars is too far apart, a constraining three-body problem will occur, which is easy to produce a long-term stable triad system.

Triple refers to a cluster system composed of three stars. These three stars maintain each other by gravity, and in many cases, the luminosity is very different.

This is because the triad system in "Three Bodies" is actually unstable. It may only take a few million years for stars to be expelled, or two of the stars will collide and eventually evolve into a stable state.

South Gate II A is a yellow dwarf star like the sun, with a mass about 1 times that of the sun; B is an orange dwarf star with a mass slightly smaller than the sun, about 0.9 times that of the sun.

In order to explain this phenomenon, they speculated that there may be a lot of dust around the neighboring star c, or a planetary ring, resulting in the deviation of brightness. If the planetary ring is speculated correctly, then the shape of the neighboring star c looks about the same as that of Saturn, and the size of the planetary ring is 3-4 times that of Saturn's ring.

What is a tripo? Give an example.

1. It is a system composed of three stars called triad ~ two are called binary stars. For example: centarus a-south gate two closest to the earth except the sun is a triad. The closest to the Earth is the C star, also known as the neighboring star. According to the number of star members, it can be called tria, quadrupe, etc.

2. A system composed of three stars can also be called a tria, and a system composed of four stars is called a quadruple, and so on.

3. Tria conjunction refers to the mutual relationship between three or more planets or stars in the constellation. The tria includes the mutual relationship between the three stars, such as the sun, the moon and the Mercury, which are arranged at an angle of 120 degrees in the same constellation.

Is the three-star system environment really as terrible as described in "Three Bodies" and has no rules to follow? _Baidu...

1. The novel describes the civilization environment of the Samsung system in a creepy way. The operation of the three stars there is completely irregular, causing the planetary civilization there to suddenly fall into a state of extreme cold and freezing without warning, and suddenly exposed to flame-like heat, without any irregularity. Can be followed.

2. This is because the triad system in "Three Bodys" is actually unstable. It may only take a few million years for stars to be expelled, or two of the stars will collide and eventually evolve into a stable state.

3. In other star systems, it is not uncommon to contain multiple stars, and there are also many triple star systems. For example, the closest star system to the solar system - South Gate II.In South Gate II, a rocky planet was even found, and it may be in the habitable zone and is a potentially habitable planet.

4. It is not necessarily absolutely irregular, but there is no regularity in a relatively short time scale, and only a long scale will show regularity. It is difficult to generate life or civilization in the Samsung system. To be precise, it is a living being based on human beings, because there should be many life forms in the universe, which is unimaginable.

In the universe, is there really a triar system mentioned in the Three Bodies?

1. Of course there is, and the nearest tria system is the closest star system to us - South Gate II, or Alpha Centauri.This tria-star system is located 4 light-years away, and it is the prototype of the novel Three Bodies. However, at present, astronomers have not discovered a chaotic triplet system like the one in The Three Bodies.

2. So is there a "three-star system" in the universe? The answer is naturally no. In the "three-star system" in the "Three-Body", the three stars are similar in size and interact with each other.

3. In fact, there are not only three-star systems, but also four-star, five-star, etc., which are relatively common in the universe. The position of the sun is the edge of the Milky Way, and the density of stars near the center of the Milky Way is greater, and the possibility of multi-star systems may be greater.

Is there a three-star system like a three-body galaxy in the universe? Why?

1. Even the writer himself wrote in his work that the "three-star system" composed of three stars is very unstable, so it is basically impossible to exist in the real universe.

2. Just like the three-body civilization, human beings can't adapt to the changing weather for no reason.

3. There are many three-star systems in the universe. It is generally believed that three stars are formed at the same time.

4. Stable three bodies There is also a stable three-star system, that is, two of the celestial bodies are relatively close, forming a small double star system, and then the distance between this system and the other celestial body is farther, and much far away, forming a higher-level double-star system. That is, the hierarchical twin stars.For example, the relationship between the sun, the earth and the moon is this kind of system.

What are the characteristics of the Samsung system? The interaction between stars. The existence of planets

1. Uranus: the slope of rotation is the greatest. Neptune: The planet farthest from the sun, with the most violent atmospheric activity and the fastest surface wind speed. It is the only planet discovered using mathematical predictions rather than planned observations.

2. This kind of system is also difficult to exist stably. Therefore, the three-star system found so far is a twin-star system composed of a pair of double stars and another distant star, that is, the stacking of two layers of double star systems. These three stars are far apart from the other stars, so the three-star system is often ignored by the gravitational influence of other stars.

3. For the triad system, it is also possible to form planets around any star. For example, there is one planet around Centaur B, and there are at least two planets around the neighboring star. In the triad system HD 188753, the main star also has at least one planet.
