What is the largest star in the Milky Way?

The largest is the star VV A in the constellation Cepheus.

The small bright spot on the left is the sun, and the giant on the right is the Vv star A in the constellation Cepheus (the volume is too large, the display is incomplete, if you show all the vv stars, the point of the sun will be too small to be seen).

The largest star in the Milky Way is Seamount.

At a distance of 7,500 light-years from Earth, Seamount is 120-150 times the mass of the Sun and about 4 million times brighter than the Sun.

Black holes, also known as collapse stars, have a huge black hole at the center of the Milky Way (Sagittarius A) with a mass about 250,000 times that of the Sun!

The star Aita Karifa is about 1 million times the mass of the Sun and emits 5 million times the intensity of the Sun. Seen in the book

Sadly, although scientists are making optical telescopes bigger and bigger, they still can't see the true face of the center of the Milky Way. Later, they finally understood that there was a large amount of dust near the silver heart, which was like a thick veil that obscured the scientists' vision and prevented them from seeing what was going on there.

The largest mass is A1 in the figure

The largest is Vv A, the constellation Cepheus

Betelgeuse, 400 times the diameter of the sun.

What is the largest star in the Milky Way?

It's Sirius. You don't believe it.

How many stars are there in the Milky Way? Answer: More than 200 billion.

The Milky Way is the galaxy to which the Earth and the Sun belong. Because of the bright band projected on the celestial sphere by its main part, it is called the Milky Way by our country. There are more than 200 billion stars in the Milky Way.

The Milky Way looks like a large disk with a slightly bulging center, with a diameter of about 100,000 light-years, and the Sun is located at the center of the Milky Way. The drum is a silver heart is a dense area of perseverance, so it looks at a white expanse. The Milky Way looks like a giant whirlpool with four spiral arms.

The solar system is located in one of the spiral arms (the Orion arm) and rotates counterclockwise (it takes 100 million years for the Sun to revolve around the galactic core).

The Milky Way is in the shape of a vortex, with 4 spiral arms extending evenly and symmetrically from the center of the Milky Way. The center of the Milky Way and the 4 spiral arms are places where stars are concentrated. From a distance, the Milky Way looks like a large discus for physical exercise, with a diameter of 100,000 light-years, equivalent to 946,080,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000

The thickest part in the middle is about 12,000 light years. The Sun is located on a spiral arm called the Orion Arm, about 10,000 light-years from the center of the Milky Way.

There are about 200 billion stars in the Milky Way, and the Sun is just one of many. In the Milky Way, there are many stars and nebulae that form disk-like structures with a diameter of 10,200,000 light-years, and the closer you get to the center of the Milky Way, the denser the star. Although the Sun is not a big star, it is more massive than 75% of the Milky Way's red dwarfs.

There are about 200 billion stars in the Milky Way.

There are about 200 billion stars in the Milky Way, which is still the stars that can be monitored and calculated by current technology, and there are actually many more stars in the Milky Way. Among the many stars in the Milky Way, the Sun as we know it is actually a type of star, and it is also the more famous star in the Milky Way.

In the Milky Way, these stars and the nebulae orbiting in the middle of the galaxy form a disk-like structure with a diameter of 10,200,000 light-years, and the average distance between these stars is also up to four light-years. The closer the stars are to the center of the Milky Way, the higher their density will be as they get closer to the center of the Milky Way.

Although the star as we know it is the Sun, and the stars seen with the naked eye are larger than the Sun, this does not mean that the Sun is a small star in the Milky Way. Seventy-five percent of the stars in the Milky Way are red dwarfs, so they are less massive than half the Sun and are largely invisible to the naked eye.

The top 10 stars in the Milky Way are as follows:

1. Shield seat UY

The constellation Scutellus is the largest star in the universe, a red supergiant located in the constellation Scutellus, which is 5 billion times the size of the Sun. Due to the density and instability of its base, it is not possible to determine its exact size for the time being.

2. Cygnus NML

Cygnus NML is one of the largest known stars with a radius of 1640R, and is also one of the most luminous stars, and the fusion of Cygnus also produces oxygen, making it the most Earth-like planet.

3.、woh g64

WOH G64 is a red supergiant discovered in the Great Mageren Galaxy, located 160,000 light-years from Earth and more than 7 billion times the size of the Sun.

4. Westloo 1-26

Westloo is one of the largest stars ever discovered, about 1,530 times the sun's half-thrust diameter, and is a supergiant star with a very high temperature, the first intense radio source variable star discovered in human history.

5. Sagittarius VX

Sagittarius is a pulsating red supergiant located in the constellation Sagittarius, which is 1520 times the diameter of the Sun, and its volume is large, but the density is small, only 12 times that of the Sun.

6. Cygnus ky

The constellation Cygnus is one of the brightest stars in the universe, 270,000 times brighter than the Sun, with a radius of about 1420r and about 5,153 light-years from Earth.

7. Canis Major VY

VY Canis Major is a red supergiant located in the constellation Canis Major, located 3,900 light-years from Earth, with a mass of about 17 times that of the Sun and a radius of 1,069 times that of the Sun.

8. Scorpio VH

VH Scorpio is a red supergiant star located in the constellation Scorpius, and its radius is between 1287-153 of the radius of the Sun.

9. The fairy king scatters the nuclear seat RW

RW Cepherd is a star in the constellation Cepheus, an unusual supergiant star whose radius changes between 981-1758R, and its luminosity is constantly changing, barely visible to the naked eye at its brightest.

10, Cassiopeia pz

The Cassiopeia PZ is a red supergiant located in the constellation Cassiopeia and one of the brightest stars in the red supergiant, with a radius of about 1790-1940 times the radius of the Sun and 17,800 light-years from Earth.

The largest stellar constellation in the Milky Way, Shield UY.

As a red supergiant, UY Shieldus has a very large size, extremely low density, and a relatively unstable state. The star will erupt a large amount of material into space at a very fast rate, forming clouds around it.

The star is almost completely obscured by the dust and gas, and rapidly loses mass due to its low density and high brightness, and is in a similar state to most red supergiants (such as Canis Major). Because the dust and gas are not very transparent, hindering measurements, and due to the limitations of modern technology, astronomers are still unable to determine their size.

Stars are giant spheres made of light-emitting plasma, mainly hydrogen, helium, and trace amounts of heavier elements. On a clear night, there are countless points of light in the night, and most of them are stars except for a few planets. The Sun is the closest star to Earth, and almost all of the stars that can be seen at night are in the Milky Way.

Of the approximately 300 billion stars in the Milky Way system, only a fraction of them can be observed. Human beings have a long history of observing stars, and there are many ways to observe them. The brighter stars are divided into constellations and clusters, some of which have their own names.

The brightness of a star is known as magnitude, and the brighter the star, the lower the magnitude. Astronomers also compiled star catalogs to facilitate research.

Stars undergo nuclear fusion at their cores to produce energy that is transmitted outward, then radiated from the surface into outer space. Once the nuclear reaction in the core is exhausted, the life of the star is coming to an end. At the end of life, stars also contain degenerate matter.

Differences in the size and mass of stars lead to different outcomes: white dwarfs, neutron stars, black holes.

Two or more gravitationally bound stars can form binary stars that can have a significant impact on their evolution when they are in relatively close orbits.

The ranking of the largest stars in the universe is as follows:1. Shield seat UY

2. Canis Major VY

3. Tian Li Nian counts the planet of Goose nml.

4、woh g64

5. Westloo 1-26

6. Sagittarius VX

7. Cepheus VV

8. Canis Major VY

9. Orion Planet.

10. High-fiber Gemini star.

Shield seat UYIt is one of the top ten supergiants in the universe, it belongs to the star, and this planet is not suitable for human life because there is no gas and no rocks on it. So on this planet humans can't breathe, but this planet is very big, the diameter of this planet.

VY Canis Major can be called the first of all planets and is a supergiant star. The planet is about 4,500 light-years away from Earth and, according to experts, is estimated to be about 50 times more massive than the Sun.

The number of stars in the Milky Way is between 100 billion and 400 billion cherry sails.

The Milky Way, a barred spiral galaxy (a type of spiral galaxy) where the solar system is located, is elliptical in the shape of an elliptical disk with a huge disk structure, and the latest research shows that the Milky Way has four well-defined and fairly symmetrical spiral arms, which are 4,500 light-years apart. The number of stars in the Milky Way is between 100 billion and 400 billion. The Milky Way as a whole rotates poorly, with a rotation speed of about 220 kilometers per second at the Sun, and the Sun orbits around the galactic center for about 100 million years.

The visual absolute magnitude of the Milky Way is equal, and the total mass of the Milky Way is about a trillion times the mass of the Sun. The age of the Milky Way is about 10 billion years old, and the scientific community believes that the universe occurred about 13.8 billion years ago. The Milky Way has two companion galaxies:

The Great Magellanic Galaxy and the Small Magellanic System.

The largest galaxy

They are all members of the Local Group of Galaxies and are part of the Virgo Supercluster, which in turn makes up the Laniakea Supercluster. The Milky Way galaxy is composed from the inside to the outside, including the galactic heart, the galactic core, the galactic disk, the galactic halo, and the galactic crown. Most of the Milky Way** regions are old stars (mainly white dwarfs), and the outer regions are mostly nascent and young stars.

There are more than a dozen satellite galaxies scattered around the area of hundreds of thousands of light-years, and the Milky Way grows by slowly swallowing up the dwarf galaxies around it. M109 (NGC3992) is a barred spiral galaxy located in the constellation Ursa Major at a distance of about 41 million light-years. M109 is the largest galaxy in the Northern Ursa Major Cluster, accompanied by Messier-108.
