Question

tell me eassy of andromeda galaxy

Answer 1

The Andromeda Galaxy (/ænˈdrɒmɪdə/), also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs(2.5 million light-years) from Earth, and the nearest major galaxy to the Milky Way.[4] Its name stems from the area of the sky in which it appears, the constellation of Andromeda.

Andromeda Galaxy
The 2006 observations by the Spitzer Space Telescope revealed that the Andromeda Galaxy contains approximately one trillion stars,[10] more than twice the number of the Milky Way’s estimated 200-400 billion stars.[13] The Andromeda Galaxy, spanning approximately 220,000 light years, is the largest galaxy in our Local Group, which is also home to the Triangulum Galaxy and other minor galaxies. The Andromeda Galaxy's mass is estimated to be around 1.76 times that of the Milky Way Galaxy (~0.8-1.5×1012solar masses [9][10] vs the Milky Way's 8.5×1011 solar masses).

The Milky Way and Andromeda galaxies are expected to collide in ~4.5 billion years, merging to form a giant elliptical galaxy[14] or a large disc galaxy.[15] With an apparent magnitude of 3.4, the Andromeda Galaxy is among the brightest of the Messier objects[16]- making it visible to the naked eye on moonless nights,[17] even when viewed from areas with moderate light pollution.

Answer 2

The Andromeda galaxy is a galaxy close to ours. It is also a spiral galaxy.It's distance is about 2.5 million light years away from us . It’s the most distant thing you can see with your eye alone.  Although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours. Excluding the Large and Small Magellanic Clouds, which can’t be seen from northerly latitudes, the Andromeda galaxy – also known as M31 – is the brightest galaxy you can see. At 2.5 million light-years, it’s also the most distant thing visible to your unaided eye.
