How many light years is the Milky Way and how many light years is the diameter of the Milky Way?

The Milky Way is the galaxy in which the solar system is located, including 1,000 to 400 billion stars and a large number of star clusters, nebulae, and various types of interstellar gas and interstellar dust. It has a diameter of about 100,000 light-years and a thickness of about 12,000 light-years at the center, and the total mass of visible matter is about 140 billion times the mass of the Sun. In the past, the Milky Way was thought to be a spiral galaxy like the Andromeda Galaxy, but the latest research suggests that the Milky Way should be a barred spiral galaxy.

At present, an international team of researchers has made mass estimates of the Milky Way and the Andromeda Galaxy, and found that the mass of the Milky Way is only half that of the Andromeda Galaxy.

The Milky Way has a massive disk structure with a galactic core and four spiral arms, which are 4,500 light-years apart. The Sun is located on the Orion Arm, an arm of the Milky Way, at a distance of about 26,000 light-years from the center of the Milky Way. In June 2013, NASA announced the clearest Galaxy image with a 100-million-pixel capacity of 457MB.

Astronomer Maria German believes that the study of the disk of the galaxy's star clusters shows that the inner cluster of stars in the Milky Way is older, while the outer stars are younger, and it can be speculated that the formation process of the Milky Way began from the interior and gradually evolved to a diameter of more than 100,000 light-years. Scientists say the investigation also uncovered new evidence that the Milky Way also swallowed up many small galaxies as it grew, and that objects from other galaxies merged into the Milky Way's interior.

Due to the large amount of gamma rays emitted from the Milky Way**, Stephen Hawking once claimed that his observations showed that the center of the Milky Way was a huge black hole.

The Milky Way is the star system in which the solar system is located, including 120 billion stars and a large number of star clusters, nebulae, and various types of interstellar gas and interstellar dust. Its total mass is 140 billion times that of the Sun. Most of the stars in the Milky Way are concentrated in an oblate sphere of space, which is shaped like a discus.

The protruding part of the oblate sphere in the middle is called the "nuclear sphere", with a radius of about 7,000 light-years. The middle part of the nuclear ball is called the "silver core", and the surrounding area is called the "silver plate". Outside the silver disk there is a larger sphere, where there are few stars and less dense, called the "galactic halo", with a diameter of 70,000 light years.

The Milky Way is a spiral galaxy with a spiral structure, i.e., with a galactic core and two spiral arms, which are 4,500 light-years apart. The speed and period of rotation of each part of the silver vary depending on the distance from the silver core. The Sun is about 10,000 light-years away from the galactic center, orbiting it at a speed of 250 kilometers and seconds, and the period of its rotation is about 100 million years.

Throughout the ages, I don't know how many emperors and generals, border soldiers, and sassy people.

Guests and poets have left an immortal chapter for the Great Wall. Biansai poetry has become an important genre in classical literature. Such as Li Bai.

"The long wind is tens of thousands of miles, blowing the Yumen Pass",The Great Wall of Astronomy marked by the two astronomers at the time was 200 million light-years away from Earth's Milky Way. It is 500 million light-years long, 300 million light-years wide, and 15 million light-years thick.

It is about 100,000 light-years in diameter.

First of all, the Milky Way is made up of three parts. The central part of the nuclear sphere is 3000 light-years in diameter and is ellipsoidal. The silver disk is the main body of the Milky Way, with a diameter of about 80,000 light-years, a thickness of about 10,000 light-years, and a thickness of about 3,000 to 6,000 light-years at the edge.

It is made up of planets that are less than 10 billion years old and have a high content of heavy metals. Outside the galactic disk is a spheroid called a galactic halo of sparse stars and interstellar material, about 100,000 light-years.

The milky way galaxy (English: milky way galaxy), is a type of spiral galaxy (a type of spiral galaxy) where the solar system is located, in the shape of an elliptical disk, with a huge disk structure, the latest research shows that the Milky Way has four clear and fairly symmetrical spiral arms, the spiral arms are 4500 light-years apart. The number of stars in the Milky Way is between 100 billion and 400 billion.

The Milky Way as a whole has a poor rotation. The rotation speed at the Sun is about 220 kilometers per second, 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 Large Magellanic Galaxy and the Small Magellanic Galaxy. They are all members of the local group of galaxies and are part of the Virgo Supercluster; It is part of 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 an area of hundreds of thousands of light-years, and the Milky Way grows by slowly devouring the surrounding dwarf galaxies.

The diameter of the Milky Way is 100,000ly.

The Milky Way is the barred spiral galaxy in which the solar system is located, including 1000 400 billion stars and a large number of star clusters, nebulae, and various types of interstellar gas and interstellar dust.

With a total mass of about 210 billion times that of the Sun, it belongs to the local group of galaxies, and the nearest extragalactic galaxy is the Dwarf Canis Major galaxy, 42,000 light-years away.

The Milky Way is the home of the universe where human beings live, and it is also one of the important objects for us to explore the universe. The size of the Milky Way determines its importance, and it is even bigger than we can imagine. The Milky Way is a very large celestial body, about 100,000 light-years in diameter and 1,000 light-years thick, containing an infinite number of stars, planets, dust and gas clouds.

A light-year is a unit of measurement of the distance of a celestial body, which refers to the distance traveled by light in a year as it travels in a vacuum, which is about 100 million meters. It is estimated that the center of the Milky Way is about 10,000 light-years away from the solar system, and the edge of the Milky Way is nearly 100,000 light-years from the solar system. This means that even if we were to travel at the speed of light per year, it would take tens of thousands of years or more to reach the center or edge of the Milky Way.

The Milky Way galaxy has a large number of planetary stockings, with about 1,000 planets that may be similar to Earth. Through the exploration and study of these planets, we hope to discover more planets similar to Earth that may have life, and dig deeper into their physical and chemical properties and life characteristics.

Overall, the sheer size and complexity of the Milky Way means that there are still many uncertainties and unknowns about what we know about it. However, with the continuous development of science and technology, we have more and more opportunities and ways to understand this mysterious universe and understand the various interstellar matter and life phenomena in it, so as to understand the nature of the universe more deeply.
