What cluster does the Milky Way belong to? What galaxy cluster does the Milky Way belong to

The Milky Way and nearly 40 other galaxies that are not very far apart form a cluster of galaxies, all of which have a more or less mutual gravitational pull. Of these, the Milky Way and the Andromeda Galaxy are the two largest and closest galaxies, and the distance between them is only 2.5 million light-years Reference.

The Milky Way is the solar system.

The barred spiral galaxy in which it is located, including 1000 400 billion stars and a large number of star clusters, nebulae, and various types of interstellar gas and interstellar dust, is seen from Earth in a silvery-white ring around the sky. With a total mass of about 210 billion times that of the Sun, it belongs to the local group of galaxies, the nearest extragalactic galaxy.

It is the Dwarf Canis Major galaxy located 42,000 light-years away from the Milky Way.

Characteristics of the Milky Way

The Milky Way is the star system in which the solar system is located, including 1500 400 billion stars and a large number of star clusters, nebulae, as well as various types of interstellar gas and interstellar dust.

210 billion times.

Most of the stars in the Milky Way are concentrated in a monophytic sphere of space, which is shaped like a discus. The protruding part of the oblate sphere in the middle is called the "nuclear sphere" and has 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 galactic disk there is a larger, spherical region, where there are fewer stars and less dense, and is called a "galactic halo" by branches, with a diameter of 70,000 light-years.

90% of the Milky Way is made up of stars. There are many types of stars, according to their physical properties.

With their chemical composition, spatial distribution, and movement characteristics, stars can be divided into five star families. The youngest extreme star families The stars are mainly distributed in the spiral arms of the silver disk; The oldest extreme star families are mainly found in the galactic halo. Stars often clump together.

Our galaxy.

In the Virgo galaxy cluster.

A galaxy cluster is a group of galaxies that are clustered together to form a certain mechanical relationship with each other.

A cluster of galaxies that contains a small number of galaxies is called a group of galaxies. The group of galaxies in which the Milky Way is located is called the local group of galaxies, and there are about 50 member galaxies (there are different opinions).

A larger group of galaxies consisting of several adjacent groups of galaxies is called a galaxy cluster. The cluster of galaxies in which our Milky Way is located is called the Virgo Cluster.

The Virgo Cluster is an irregular cluster of galaxies located in the constellation Virgo, consisting of more than 2,500 galaxies and an average distance of 19 million parsecs (60 million light-years) from us, making it the closest irregular cluster to Earth. The Virgo Cluster occupies a long area of the sky, with an angular diameter of about 12°; The line diameter is about 13 million light years. The Virgo Cluster occupies at least a large area of the celestial sphere at 12h 13h right ascension and +20° -20° declination.

The supergiant elliptical galaxy M87

NGC4486) is located at the center of the Virgo Cluster, with hundreds of member galaxies in an elliptical celestial region of 12° 10° in the central region. Its structure is quite complex and may be a projection of several galaxy clusters.

Both the Virgo Cluster and the Local Group of Galaxies in which the Milky Way is located belong to the Local Supercluster, and the Virgo Cluster may be the central dense part of the Local Supercluster.

The present supercluster (Virgo supercluster.

is an irregular supercluster of galaxies that includes the solar system.

A supercluster of galaxies consisting of a group of galaxies including the local group of galaxies in which the Milky Way is located. It resembles a pancake in a pan and covers an area about 100 million light-years in diameter, in the observable universe.

One of the millions of superclusters of galaxies.

The Virgo Supercluster is also the Laniakea Supercluster.

part. It is also part of the Galactic Filigree Pisces-Cetus Supercluster complex. The central region of the cluster is about 60 million light-years away from Earth and is located in the constellation Virgo.

The Virgo Supercluster contains about 100 groups of galaxies and clusters of galaxies, with the Virgo Cluster at its center. The Local Group is located at the edge of the Virgo Cluster and continues to move away from the Virgo Cluster.

A galaxy cluster is a group of galaxies that are relatively concentrated and close together. The Milky Way is relatively large and the galaxies that are closer to it are relatively far away, so there is no galaxy cluster to which it belongs. However, the group of galaxies composed of a large number of galaxies is called a galaxy group, and the group of galaxies where the Milky Way is located is called the local galaxy group.

A galaxy group is a group of galaxies with a scale of 100,200,000 parsecs that are related to each other. The number of galaxies in the galaxy group is about 100 or less, and it is a cluster of galaxies with small scales and star coefficients. The group of galaxies is loose in structure and rather irregular in shape, with spiral galaxies, irregular galaxies and some dwarf elliptical galaxies being the main members, and very few giant elliptical galaxies and S0 galaxies.

This group of galaxies is a general term for galaxies in space with the Milky Way as the center and a radius of about 3 million light-years. There are more than 40 member galaxies in this group, including two giant spiral galaxies, the Milky Way and Andromeda galaxies, a medium-sized spiral galaxy, a triangular galaxy, two irregular galaxies, the Large Magellanic Cloud and the Small Magellanic Cloud, and some other dwarf elliptical galaxies and irregular galaxies.

The total mass of this group of galaxies is about 100 billion solar masses, of which the Milky Way and the Andromeda Galaxy account for the vast majority. The local group of galaxies is a typical open group of galaxies, which does not tend to concentrate towards the center, but there is a phenomenon of three or five galaxies converging into subgroups. It is known that there are two subgroups centered on the Milky Way and the Andromeda Galaxy.

The Local Group is a member of the Local Supercluster.

The Seyfert system and more. Milky Way

Other galaxies are called extragalactic galaxies, and more than 1 billion extragalactic galaxies have been discovered.

What other systems are there besides the Milky Way?

There are only three extragalactic galaxies visible to the naked eye, namely the Andromeda Galaxy M31, the Large Magellanic Galaxy, and the Small Magellanic Galaxy.

As early as the 10th century, he sailed to the equator.

Nearby Arabs have already discovered two cloud-like objects, the Great Magellanic Galaxy.

It wasn't until 1521 that the navigator Magellan named the Great and Small Magellanic galaxies after him and gave an accurate description of them.

The Milky Way is part of the Virgo Supernova Cluster, which spans 60 million light-years and contains more than 2,500 galaxies. The Virgo Supernova Cluster, in turn, belongs to the Laniakea Supercluster, which spans 100 million light-years and contains about 500 known clusters and groups of galaxies.

The Milky Way is the abbreviation of the Milky Way, and it is also the galaxy to which our solar system belongs, with a diameter of 100,000 light-years, which is very huge.

The Milky Way is in a spiral shape, with four 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 the constant shouting of rental stars is concentrated. From a distance, the Yinge River system resembles a large discus for physical exercise, with a diameter of 100,000 light years, equivalent to 10,000 kilometers.

The thickest part in the middle is about 3000-6500 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.

1. The Milky Way belongs to the local group of galaxies, which in turn belongs to the larger Virgo supercluster.

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

3. The total mass is about 210 billion times that of the Sun, and it belongs to the local group of galaxies, and the nearest extragalactic galaxy is the Great Incanus Cavis dwarf galaxy 42,000 light-years away from the Milky Way.
