Reply to comment by darkgothmog in Galactic cannibal Andromeda feasts on smaller galaxies, cosmic leftovers reveal by nikola28

Interesting. Less dark matter isn't what I was referring to specifically though. Still seeing it listed as about 200,000 light-years in diameter, which is double the Milky Way.

I think you're right. According to a quick google search Andromeda has about a trillion stars compared to the estimated 300 billion the Milky Way has.

It has way more stars but it’s mass could be anywhere from 1.8x ish to actually less than the Milky Way (according to wiki). There’s some pretty big error bars on it.
