What are the two largest galaxies in the Local Group?

What are the two largest galaxies in the Local Group?

The exact number of galaxies in the Local Group is unknown as some are occluded by the Milky Way; however, at least 80 members are known, most of which are dwarf galaxies. The two largest members, the Andromeda Galaxy and the Milky Way, are both spiral galaxies with masses of about 1012 solar masses each.

Which type of galaxy is the largest galaxy in the Local Group?

The three largest members of the group are our Milky Way (second-biggest), the Andromeda galaxy (biggest), and the Triangulum Galaxy. The other galaxies in the Local Group are dwarf galaxies, and they’re mostly clustered around the three larger galaxies.

What two galaxies dominate local groups?

Here in the Local Group, our two largest galaxies dominate: Andromeda and the Milky Way.

What are the two main galaxies?

Key Facts & Summary

• There are four main categories of galaxies: elliptical, spiral, barred spiral, and irregular.
• The most common type of galaxy found throughout the universe is the spiral galaxy.
• Around two-thirds of all spiral galaxies have a bar-like structure – thus they are classified as barred spiral galaxies.

What are the three largest galaxies in the Local Group?

Bottom line: The Local Group of galaxies consists of three large galaxies – the Andromeda Galaxy (biggest), our Milky Way (2nd-biggest) and the Triangulum Galaxy (3rd biggest) – along with 50 or so much-smaller dwarf galaxies.

Is the Virgo supercluster bigger than the Milky Way?

The Virgo Supercluster’s volume is very approximately 7000 times that of the Local Group or 100 billion times that of the Milky Way.

Is the Pinwheel galaxy in the Local Group?

The spiral galaxy M33, also known as the Pinwheel Galaxy, is the third-largest galaxy in the Local Group after the Milky Way and M31.

Is the Virgo Supercluster bigger than the Milky Way?

Is Local Group bigger than supercluster?

The density of large galaxies in the Virgo Cluster is about ten times greater than that in the Local Group. The enormous gravity of the Virgo Cluster makes it the center of a larger structure, called the Local Supercluster. The Local Group is just a tiny member of the Virgo Supercluster, located on the outskirts.

Which is larger a group of galaxies or a galaxy cluster?

Clusters of galaxies Clusters are larger than groups, although there is no sharp dividing line between the two. When observed visually, clusters appear to be collections of galaxies held together by mutual gravitational attraction.

Which is the largest galaxy in the local group?

Andromeda is the biggest and our Milky Way is the 2nd biggest galaxy in the Local Group. These large galaxies also have many satellite galaxies (it is like planets that have many satellites/moons).

Is the Milky Way in a local group?

The Milky Way is the galaxy where our Earth exists. Our Milky Way exists in a group of galaxies and these all galaxies are called Local Group Galaxies. So, Local Group (LG) is a galaxy group where more than 50 galaxies exist with our Milky Way and Andromeda (neighbor galaxy).

How are the Local Group galaxies like a dumbbell?

The local group galaxies made a shape like a “dumbbell”. Andromeda and its satellite galaxies form one side lobe of the dumbbell whereas Milky Way and its companion galaxies form another side of the dumbbell lobe structure. 1) How large is the local group?

Which is the largest spiral galaxy in the universe?

The two largest members, the Andromeda Galaxy and the Milky Way, are both spiral galaxies with masses of about 10 12 solar masses each, and each have their own system of satellite galaxies:
