Is there a planet in the vast universe that is eight billion times larger than the sun?

Yes VY Canis Majoris (also known as VY Canis Major, VY CMA) is a red supergiant located in the constellation Canis Major, located 5,000 light-years from Earth, with an apparent magnitude. It is speculated that it has a mass of about 30 40 times the mass of the Sun [1] and a diameter of about 1800 2100 times the diameter of the Sun, surpassing the orbit of Saturn and being the largest of any known star. VY Canis Major is not only huge, but also has 500,000 times the luminosity of the Sun, so it is also classified as a supergiant.

VY Canis Major is at the end of the stage of stellar evolution and is spewing out large amounts of gas at a massive rate. In the future, it may trigger a supernova**.

Do you mean large mass or volume?

I'll give you an example.

The largest star discovered so far is:"Immortal King vv"The diameter is 3,700 times that of the sun.

The most massive stars found so far are:"pistol star"The mass is 200 times that of the sun.

8 billion times larger is unlikely.

There must be, there is everything in the world, but human beings have not yet explored it.

Ironclad no, it can't resist gravity, and it will collapse into a black hole.

Andromeda is twice as big as the Sun, and Wandering is twice as big as the Sun.

There are too many, the sun is just a very ordinary star in the Milky Way, and the famous Sirius is twice as big as the sun.

<> largest star currently discovered is the constellation Canis Major, which is 1 billion times larger than the Sun.

How many times the mass of the largest star in the universe is the Sun?

It should be the constellation Uy, which is 9 billion times larger than the Sun.

The largest star that can be identified so far is called VY Canis Major, a red supergiant located 4,800 light-years from Earth. It is about 2.8 billion kilometers in diameter, about 2,000 times the size of the Sun, and 1 billion times larger in volume. If you put the star Canis Major in the position of the Sun, its edge will exceed the orbit of Saturn.

But it's not too massive, only about 40 times that of the sun.

There are also several huge red supergiants, probably similar in size.

The most massive stars currently found in the Milky Way are about 180 times the mass of the Sun and 200 times the mass of the Sun. It has been reported that there is a spider nebula in the Large Magellanic Cloud (an extragalactic galaxy) with a large number of newborn stars in the supercluster R136. In this supercluster, there are four stars with supermassive masses, including R136A1, which is more than 300 times the mass of the Sun, making it the heaviest star ever discovered.

If it is used as a container, it can hold about 4.5 billion suns, which is 1.3 million times the size of the earth. The constellation UY is about 10,000 light-years away from Earth! It's a pretty long distance, so much so that it didn't take long for humans to discover it.

Based on observations, astronomers estimate that it has a mass of 7-10 times the mass of the Sun, so its density is extremely low, and its interior is composed of air clouds. and a more unstable state. The star erupts a large amount of material into space at a very fast rate, forming clouds around it.

It is estimated that its life will come to an end in tens of millions of years, with a supernova**, and there is also a theory that it will evolve into a black hole.

The most massive celestial body discovered by mankind is R136A1, which is about 351 times the mass of the Sun and 100 million times that of the Earth.

Planets larger than galaxies appear? If there were, it would be terrible.

From a scientific point of view, planets have limits. If they are too big, they become stars. And stars also have a theoretical limit. With more than 150 times the mass of the Sun, it will be difficult to find more material and cram it into the star.

To get a star like R136A1 (the brightest star in the R136A cluster) is equivalent to 260 solar masses. So far, the theoretical upper limit is around 300, but this could be pushed even higher.

But let's assume that there is a star with 500 times the mass of the Sun and does not need so much complex matter. Over its hundreds of thousands of years of life, it will lose about 200-300 too much of its solar mass – a star of this size simply doesn't want to exist.

If a planet becomes too large (say, 20 times the mass of Jupiter), then its gravitational pull will be so strong that it will collapse and nuclear fusion will begin – it will become a small star.

So no planet can be bigger than a star. The star avoids collapsing under its own gravity because the "photon pressure" of the light it produces pushes outward, counteracting gravity.

If it's a big, limit-large star, this causes the star to quickly deplete its energy reserves – and then, when there's no more energy left to produce light, gravity takes over and it collapses.

Such a huge star would collapse into a black hole.

And if you want to be bigger than a galaxy, there is obviously no such thing.

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 solar system is an independent galaxy with periodic movement of matter, and is one of the countless star systems that exist in the cosmic celestial bodies, and the diameter of the solar system is about 2 light years, which is also the scope of the solar system to occupy the infinite natural space of the universe.

The universe is a concept of infinite natural space, a natural celestial body that has no beginning and no end, boundless, endless, infinite matter and infinite space, and is composed of countless stars and their star systems, each star system is an independent entity of periodic movement of matter, all controlled by a star (sun) with a huge mass, all composed of a star and many large planets, and the space range of each star system. This is determined by the size of the surface involved in the star's magnetic field.

All stars in the universe congenitally have an invisible huge magnetic field, and the spatial range of the stellar magnetic field is the space range of the galaxy occupying the universe, that is, the space range naturally formed by the star system. A natural phenomenon that drives the circular motion of various objects in the space of the star system.

Therefore, the size of a star's magnetic field will be the size of the galaxy it will form. According to the data of relevant astronomical scientists, the speed of light of the sun needs to be about 1 light year to reach the edge of the solar system, that is to say, the radius of the solar system is about 1 light year, so that the spatial diameter of the solar system is about 2 light years, and the circular space distance of 2 light years is the spatial range of the solar system.

It's endless, there's no way to tell it by accurate data. There are eight planets in the solar system. Including the Sun, Earth, comets, asteroids, and many more.

In the vast universe, the solar system is actually not very large, 26,000-28,000 light-years from the center of the Milky Way.

The diameter of the solar system's space is about 2 light-years, which is also the extent of the solar system's occupation of the infinite natural space of the universe.

Forty-second speed of light range.
