It's even bigger than that: the diameter of the main galactic disk of Andromeda is 152 000 light years. There are additional stars orbiting the galaxy in a halo

It's even bigger than that: the diameter of the main galactic disk of Andromeda is 152 000 light years. There are additional stars orbiting the galaxy in a halo with a total diameter 220 000 light years.
In comparison, Earth's moon is very much smaller, with a diameter of less than 1 light year.
- santoshalper 4y agoFor some reason I really enjoy the way you describe the moon as having "a diameter of less than 1 light year.", which is also true of my cat and the shoe I am wearing. And everything else I have ever seen or will experience in my life.
- jader201 4y agoYeah, I realized that after it was too late to edit. I posted that after a quick Google search — I originally had no idea how big it was, but new it was more the 2x the moon :) — and of course the big “110,000 light years” it returned at the top was the radius, not the diameter.
