Its diameter is around 220,000 light-years and its mass equals the mass of 1,230 billion Suns! There are about one trillion stars in the Andromeda Galaxy.
What are the 3 galactic neighbors of the Milky Way?

Will we survive the collision with Andromeda?
Four billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda. The galaxies as we know them will not survive. In fact, our solar system is going to outlive our galaxy.
What will happen to Earth when the Andromeda Galaxy collide?
Excluding planetary engineering, by the time the two galaxies collide, the surface of the Earth will have already become far too hot for liquid water to exist, ending all terrestrial life; that is currently estimated to occur in about 3.75 billion years due to gradually increasing luminosity of the Sun (it will have …
What is the farthest star ever discovered?
