The Milky Way is a house of stars, in which billions - and trillions - of stars keep repeating the same house together. Our Sun is also a star and revolves around its Milky Way Galaxy. Just like our Milky Way Galaxy, so is our neighboring galaxy which we know by the name of Andromeda.

This galaxy is like our Milky Way galaxy and it also has billions and trillions of stars. Our modern technology today is not yet able to understand this huge house of stars, yet we know a little about this galaxy. Today, you will put the same knowledge in front of you and tell 15 interesting facts about it…

Type: Spiral
Diameter: 220,000 light-years
Distance: 26 lakh light-years
Mass: 400 to 700 billion times of sun
Age: 4.5 billion years
Stars: 1 trillion
Group: Local Group

1. Andromeda is a spiral galaxy located 2.5 million light-years away from our galaxy. From Earth, this spiral galaxy is 240000000000000000000 kilometers.

2. Andromeda Galaxy is also known as Messier 31 or M31.

3. In the cluster of galaxies, Andromeda is the largest galaxy. This local cluster is a cluster of 54 galaxies.

4. Scientists believe that there are more than 1 trillion stars in this galaxy.

5. The estimated mass of Andromeda is equal to 400 billion suns. In other words, it has a mass equal to the mass of 400 billion suns (from the sun we are talking about the sun in our solar system).

6. The diameter of this spiral galaxy is 260,000 light-years.

7. Andromeda is moving towards the Milky Way Galaxy at speeds of 100–140 kilometers per second. Scientists believe that in the next few billion years, these skies can collide.

8. In 2010, a team of astronomers proposed that between 5 and 9 billion years ago, the two smaller galaxies collided with each other and merged together, and the same merger led to the Andromeda galaxy coming into existence.

9. In addition to the supermassive black hole at the center of Andromeda, there are 26 more black holes inside this galaxy.

10. This galaxy appears in the region of Andromeda constellation and hence its name is Andromeda galaxy. Andromeda was the name of a mythical Greek princess.

11. Andromeda is a massive galaxy with two small satellite galaxies known as M32 and M110. But both these skies are constantly under the influence of Andromeda Galaxy.

12. Spirals of Andromeda continue to deteriorate. This deformation is caused by the gravitational forces of the companions M32 and M110.

13. In this galaxy, huge clusters of about 450 stars revolve, some of them are so huge and full of stars that even scientists find it strange.

14. The Andromeda Galaxy is one of the farthest objects you can find with the naked eye. You will need a good spot in bright light to see it.

15. Since this is the nearest spiral galaxy to us, astronomers have studied this galaxy to understand the origin of the galaxy and the evolution of such galaxies.
