What is the estimated number of stars contained within the Andromeda Galaxy?
Answer
Perhaps a trillion stars
Andromeda is established as the mass leader within the Local Group when comparing the two primary spirals. It is credited with containing perhaps a trillion stars. This figure is significantly greater than the Milky Way's estimation, which is placed between 200 to 400 billion stars. The estimate of around 40 billion stars is associated with the third-largest spiral galaxy, the Triangulum Galaxy (M33), highlighting the massive disparity in stellar population between the two leading members and the tertiary member.
