Is Constellation 88 the star of all galaxies? Why are they all superstars Isn't it said that the Milky Way has the largest number of red dwarfs?

In fact, the constellation is one direction. If someone asks such a question: "Does the direction of 35-39 east by south belong to China?" Teachers and classmates will definitely correct this statement in geography class. Similarly, it is unreasonable to say that a constellation does not belong to the Milky Way.

However, more than 6,000 stars visible to the naked eye do belong to the Milky Way. Even supernovae in the companion galaxies of the Milky Way are close to the naked eye, let alone stars.

Among the 2 1 brightest first-class stars in the whole day, there are indeed many superstars, such as Betelgeuse, Betelgeuse, Antares and Tianjin IV ... About 65,438+00 belong to superstars or Supergiant star. In fact, this problem is not difficult to understand, because they have strong luminous ability. Epsilon star in the constellation Bojiang is a yellow dwarf star similar to the sun, which is only a little more than 1 1 light-year away from the solar system, but it is only a fourth-class star with very ordinary brightness, not to mention a further main sequence star. These superstars are not. Their luminous power is often tens of thousands or even millions of times that of the sun, so it can naturally be very bright at a long distance.

For example, Tianjin IV, which is 0/400 light-years away from the Earth, is still a big star like 1. If it is 32.6 light years away from the earth, its brightness can reach -8, almost the brightness of the waning moon. What about the sun? 32.6 light years, just a star with a magnitude of 4.86. Although visible to the naked eye, it is definitely classified as a dark star.
