Earlier quoted context omitted.
I was surprised to learn recently that we can only see 5,000 stars from Earth with the naked eye.
Depends on your definition of "star." You can see the Andromeda galaxy with your naked eye (as well as the galactic center.)
But you don’t see individual stars. When I have been out in the middle of nowhere and looked at the Andromeda galaxy, it just looks like a smudge. You need a telescope to really realize it is made up of many individual stars.
