A superstar in the depths of the universe, with a mass only 32 times that of the Sun, what about its

According to astronomers' measurements, a superstar in the depths of the universe is 4.5 billion times the size of the Sun.

In the universe, there are many celestial bodies. In addition to the special planet of the Sun, there is also a superstar in the universe, which is only 32 times the mass of the Sun, but 4.5 billion times the size of the Sun, which is really incredible.

The universe is vast, and there is not just the sun. The star Cepheid is more than 30 times the mass of the Sun, more than 700 times the diameter of the Sun, so the volume is three cubic times that of the Sun's 700.

There are more than 300 billion stars in the Milky Way, and the Sun is the closest to the Earth, so the Human Sun seems to be the largest.

Not true, but close. There are many red dwarfs and brown dwarfs that are smaller than the Sun. But the other stars are slightly larger or a little smaller than the Sun (1

several times), but there are especially many stars larger than the Sun. The largest Stevenson 2-18, (super-red giant), is 10.1 billion times larger than the Sun.

In the vast universe, the earth is only one of the asteroids, and human beings are even smaller than the universe, but this does not stop human beings from exploring the universe. Originally, it was thought that the Sun was the largest planet in the entire solar system, but as the study of the shape of the universe deepened, it became known that there are planets in the universe that are more massive than the Sun.

From the ground to the naked eye, the Sun is actually much larger than the planets, but in fact, many planets are larger than the Sun, such as Vega, Betelgeuse, etc. These shapes are often tens or hundreds of times larger than the Sun. And one sun is already 1.3 million earths, which shows the petite size of the earth in the universe.

Of course, none of these planets are the largest stars in the universe, and the largest star discovered so far in the universe is Stephenson 2 18, which is located 20,000 light-years away in the direction of the constellation Shield. The radius of Stephenson 2 18 reaches 100 million kilometers, and the size of the entire volume can accommodate 10 billion suns, and hundreds of millions of Earths have accumulated together to reach this size.

The reason why this star has become so huge is because it is a star that is on the verge of death. Stephenson 2 18 is a planet that is much more massive than other stars in its own right, and these stars will become red supergiants at the end of their development. The internal energy of supergiants produces hydrogen nuclei that expand the outer layers of the star.

In the end, the size of the red supergiant continues to increase, but the mass of the star continues to lose, and eventually the balance of the star will be broken, and there will be supernova explosions. It is speculated that the Sun will also become a red supergiant in 5 billion years, because the Sun itself is massive enough to be a red giant, and it is very similar to Stephenson2 18.

In fact, before the discovery of the red supergiant Stephenson 2 18, people once thought that the shield uy at 51 million light years was one of the largest stars in the universe, but later research found that the uy of shield is not as big as imagined, only 755 times the size of the sun. This is a bit inadequate compared to other giant stars in the universe, such as VY Canis Major and WOH G64 in the Magellanic Galaxy, both of which have a radius more than a thousand times that of the Sun.

There are many stars in the universe that are bigger than the Earth or the Sun, and they may be tens of thousands of light-years, hundreds of thousands of light-years. But it is precisely because of this that people need to understand more clearly that human beings cannot be frogs at the bottom of the well, and should also look farther ahead, so that our earth can develop better.

The earth is a sphere, we live on the surface of the earth, standing in the wilderness and looking around, we will find that the earth is like a plane, and we will not see that the earth is a sphere without entering space, this is because our earth is too big. We humans are indeed very small compared to the huge Earth, which has a diameter of 12,756 kilometers and a mass of tons (trillions of tons), but in our solar system, the Earth is just an ordinary planet, and Jupiter, which is also a planet, is much larger than the Earth.

Jupiter is 1,300 times the size of the Earth and 318 times the mass of the Earth, yet Jupiter is too small compared to the Sun. The Sun is the boss of the solar system, and its volume and mass are 1,000 times larger than that of Jupiter.

However, the Sun is only one of the hundreds of billions of stars with a galactic coefficient, and the Milky Way is about 160,000 light-years in diameter and a trillion times the mass of the Sun.

It is generally believed that there is no such huge celestial body in the universe, the largest known single star is ton 618 quasar, which is actually composed of a black hole and its agitated accretion disk, astronomers have found that the mass of this black hole is as high as 66 billion times that of the sun, but its mass is still much worse than that of the Milky Way, about 1 23 of the total mass of the Milky Way, but it is much larger than the mass of the black hole in the center of the Milky Way, about 15 of the latter, 000 times, and its mass is also larger than the mass of some dwarf galaxies, such as the large Magellanic galaxy that is very close to our Milky Way, its mass is about 10 billion times that of the sun, then it is not as big as the black hole of ton618, only equivalent to its 1 6 1 7, the Magellanic galaxy is even smaller, less than 1 billion times the mass of the sun, only a few tenths of the mass of the ton 618 black hole, and some smaller galaxies have a mass of only about hundreds of thousands of times that of the sun, For example, the Segret 2 dwarf galaxy is only about 500,000 times the size of the Sun and less than 1/100,000th of the mass of the ton618 black hole.

Black holes are a type of star, and the sheer mass of this black hole has shocked scientists who discovered it. Its Schwarzschild radius is about 195.3 billion kilometers, and its diameter is about 390 billion kilometers, which is much larger than the volume of the largest known star known to us in the constellation Uy of Shield, which is about 100 million kilometers in diameter, and the calculation shows that the volume of the Ton618 black hole is about 4.5 million times that of the Terrais UY, and if it is compared with the volume of the Sun, then the Ton618 black hole can hold 200 million billion suns.

If you compare the mass, then the difference is even greater, the mass of the Shield UY is only 8 10 times that of the Sun, but the mass of the Ton618 black hole is 66 billion times that of the Sun, so that is to say, the mass of the Ton618 black hole is about 6.6 billion times that of the largest star Shield UY, which shows that the mass of the star in the main sequence stage is much smaller than that of the galactic black hole.
