Quick Answer: What Galaxies Are In The Local Group?

What is the largest type of galaxy?

IC 1101 is a supergiant elliptical galaxy at the center of the Abell 2029 galaxy cluster and is one of the largest known galaxies.

Its halo extends about 600 kiloparsecs (2 million light-years) from its core, and it has a mass of about 100 trillion stars..

What is the biggest galaxy known to man?

It’s difficult to characterize what the largest galaxies are, because they don’t really have precise boundaries, but the largest galaxies we know of are millions of light-years across. The biggest known galaxy is IC 1101, which is 50 times the Milky Way’s size and about 2,000 times more massive.

Where does Earth sit in our galaxy?

Orion ArmEarth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy. Here we are part of the Solar System – a group of eight planets, as well as numerous comets and asteroids and dwarf planets which orbit the Sun.

What is the youngest type of galaxy?

However, observations only recently reclassified it as a barred type spiral galaxy. One of the youngest galaxies ever discovered was the I Zwicky 18 galaxy. It was estimated to be around just 500 million years old though recent observations have discovered old stars in this galaxy.

What is the local group of galaxies called?

The Local Group (also called M31 group or the Andromeda group) is the group of galaxies that includes our galaxy, the Milky Way. The group comprises over 30 galaxies, with its gravitational center located somewhere between the Milky Way and the Andromeda Galaxy.

What are the three major galaxies in the Local Group?

The 3 largest galaxies in the Local Group are, in descending order, the Andromeda galaxy, the Milky Way, and M33 also known as the Triangulum Galaxy.

What does the local group consist of?

The Local Group is the galaxy group that includes the Milky Way. It has a total diameter of roughly 3 megaparsecs (9.8 Mly), and a total mass of the order of 2×1012 solar masses (4.0×1042 kg).

What galaxy do we live in?

The Milky WayThe Milky Way. We live in one of the arms of a large spiral galaxy called the Milky Way. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre.

How many galaxies are there in space?

100 billion galaxiesAll in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.

Where is Milky Way in the universe?

The Milky Way galaxy is in the Local Group, a neighborhood of about 30 galaxies. Our nearest major neighboring galaxy is called Andromeda.

Is local group a cluster?

The Milky Way is just one galaxy located in a vast cluster of galaxies known as the Local Group. … The Local Group is just one collection of galaxies in the even bigger Virgo Supercluster. The largest, most massive galaxies in the Local Group are the Milky Way, Andromeda and the Triangulum Galaxy.

What are the 4 types of galaxy?

In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies. More than two-thirds of all observed galaxies are spiral galaxies.

What is our universe called?

Milky WayOver the next decades, the current terminology came in to use, with Milky Way as the name of our galaxy, the term Galaxy for all galaxies (groupings of billions of stars gravitationally bound), and Universe for everything.

What is our galaxy called?

The Milky WayThe Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area.

How many galaxies are near the Milky Way?

| The Andromeda Galaxy with 2 of its satellite galaxies, via Flickr user Adam Evans. Although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours.

What is the most common type of galaxy in the local group?

Spiral galaxies are the most common type in the universe. Our Milky Way is a spiral, as is the rather close-by Andromeda Galaxy.

What are 5 galaxies in the Local Group?

About the Image One of the most prominent members of the Local group is M31, the Andromeda Galaxy. It has two small satellite galaxies, M32 and M110. Also prominent in the local group is the Triangulum Galaxy (M33), Leo I, and NGC 6822.

Can humans leave the local group?

No. Neither the Milky Way nor the humans that populate a small insignificant planet around a G2 yellow dwarf star, will ever be able to exit the Local Group.
