How is the Milky Way a celestial system? What celestial body is the center of the Milky Way

Yes around the silver core.

The Sun also has a speed of revolution relative to the center of the Milky Way.

This is the classification of celestial systems from large to small: 1 5

-5.Earth.

-4.Earth-Moon system.

-3.Solar System --- 5Sun.

-2.Milky Way --- 4Other planetary star systems.

1.Universe --- 3Other star systems.

-2.Extragalactic galaxies.

Galaxy. The center is the galactic center, which is the intersection of the galaxy's axis of rotation and the galactic plane. It is the center of the silver nucleus and the center of the Milky Way. The Silver Heart is located in the constellation Sagittarius.

Direction. This region is mostly made up of massive stars. The mass of the silver core is about 4 million times the mass of the sun. Some people think that the galactic region is a massive dense nucleus, perhaps a massive black hole.

The silver core is a slightly raised part of the Milky Way**. It is a very bright spherical body, about 20,000 light-years in diameter and 10,000 light-years thick. This region is made up of a high density of stars and interstellar matter.

Among them are mainly old red stars that are about 10 billion years old. The activity of the silver core is very intense.

Galaxy.

The center of the Milky Way is the intersection of the Milky Way's axis of rotation and the galactic plane, and the Milky Way's nucleus, the silver core, is in the direction of the constellation Sagittarius. In terms of right ascension and declination, it is at 29°00 in right ascension and 29°00 in the year 2000, and this "point" is not far northwest of Gamma, near the border between Ophiuchus and Scorpio.

People use optical telescopes to try to peek into the secrets of the center of the Milky Way, and although people have the ability to make optical telescopes bigger and bigger, and can look farther and farther, they still can't see the true face of the center of the Milky Way. It was only later that the reason for this was discovered, and it was because there was a large amount of dust near the silver heart, which could obscure people's view like a white hazy fog or a yellow hazy sandstorm that blew up.

The rapid development of infrared astronomy, radio astronomy and X-ray astronomy has provided astronomers with new observational tools and means to explore the mysteries of the center of the Milky Way, because infrared, radio waves and X-rays can all pass through the dust barrier. In this way, infrared, radio waves, and X-rays from the center of the Milky Way are like messengers from the center of the Milky Way, giving us some important information about the center of the Milky Way.

In the vast space, stars are not willing to be lonely, they like to be in piles, or pairs, or groups of three or five, and some even thousands, or even hundreds of thousands, millions of them gather together to form globular clusters, some of which form the skeleton of the Milky Way. Their center is the center of the Milky Way. According to the model of the Milky Way described by the British astronomer Herschel, the Milky Way is a flat, space-limited star system, like a piece of baked cake that has been bitten unneatly by a child, and the solar system where the Earth is located is located in the center of the baked cake.

By this reasoning, the Sun should be at the center of the Milky Way, and the clusters of stars in the Milky Way should be scattered around the Solar System. According to Herschel's theory, globular clusters should be visible everywhere in the sky from Earth, but this is not the case. One-third of the globular clusters are clustered around the Big Dipper, and the remaining two-thirds are mostly located in the half-celestial sphere centered on the constellation Sagittarius.
