Until the early 1920s, the majority of astronomers believed that the Milky Way contained all of the stars in the universe. However, the claim was later discovered to be false. Around how many stars does the Milky Way actually contain?

The Milky Way is estimated to have a mass of about 100 billion solar masses, which converts to 100 billion stars. This compensates for stars that are greater or smaller than our Sun by averaging them out. Milky Way's true mass, on the other hand, is difficult to determine — some estimates place it between 100 and 400 billion solar masses.
