The closest neighbor galaxy to our very own Milky Way galaxy is the Andromeda galaxy. It was once thought to be a nebula but later, as technology developed, scientists figured out that it was actually a full-scale galaxy. Though our current technology is not sufficient enough to take us to Andromeda, it at least allows us to study the galactic body in a better way with greater details. So, are you ready for 20 interesting Andromeda galaxy facts? Of course you are! We know your curious brain is hungry!
Interesting Andromeda Galaxy Facts: 1-10
1. The Andromeda is a spiral galaxy which is located at a distance of 2.5 million light years from our galaxy. From earth, this spiral galaxy is at a distance of 2.4×1019 kilometers.
2. Andromeda is also known as Messier 31 or in short, M31.
3. In the galaxy cluster known as the Local Group, Andromeda is the largest galaxy. The Local Group is a cluster of 54 galaxies including Milky Way and Triangulum.
4. Scientists estimate that there are 1 trillion stars in the galaxy.
5. The estimated mass of Andromeda is 400 billion solar masses. Put in other words, it has the mass equivalent to the mass of 400 billion suns (by sun we are referring to the sun in our solar system).
6. The diameter of this spiral galaxy is estimated to be 260,000 light years.
7. Though Andromeda is the largest galaxy, it is not the most massive one in Local Cluster. According to scientists, Milky Way is the most massive galaxy because of more dark matter in it.
8. The Andromeda is headed towards Milky Way at a speed of 100-140 kilometers per second.
9. Scientists estimate that Andromeda will clash with Milky Way in nearly 4 billion years.
10. Andromeda has a double nucleus. At the very center or the core of the galaxy is a massive cluster of stars. But at the core, there is also at least one super-massive black hole.
