The Milky Way is a huge galaxy. It seems that astronomers aren’t even sure how many there are in the galaxy. Various estimates range from 100 billion to 400 billion, because some stars are not visible from Earth for multiple reasons: some of them being too far, too faint, or obscured by gas or dust.. If someone asks you the question though, just give them the estimate! That’s a better answer than nothing!
