Many estimates in astronomy have some uncertainty to them, and the estimate of the number of stars in our galaxy is no exception. Even the world's largest telescopes can't count the stars. They see only the brightest and nearest stars - and stars not obscured by dust.

To estimate the number of the Milky Way's stars, astronomers first assume there's nothing special about our region of space. They determine the number of different types stars in this region - then extend this knowledge to the galaxy as a whole. The most popular current models suggest the Milky Way is about 100,000 light-years across. The estimate for the number of stars is about 100 billion stars - plus or minus 50 billion.

How many star does a typical galaxy have?

Our galaxy, the Milky Way, has somewhere between 100 billion and 400 billion stars (it's difficult to estimate precisely). However, it's not really "typical"; it has more stars than any other galaxy in the "Local Group" except for the Andromeda Galaxy, which has about a trillion stars. I'm not sure there really is such a thing as a "typical" galaxy.

How many stars are there?

There are an estimated 100 to 200 billion galaxies.Scientists estimate that our Galaxy (The Milky Way) contains 200 to 400 billion stars.So taking a conservative number of 100 billion stars per galaxy, gives an approximate total of 10,000,000,000,000,000,000,000 stars. (which is 10 sextillion)It is unknown. The Milky Way galaxy contains an estimated 200 billion stars and there are an estimated 100 billion galaxies in the observable universe. However, our galaxy is significantly larger than most. That said, if we assume the average galaxy has 10 billion stars then we arrive at an estimate of 1,000 billion billion stars, or about 1 sextillion stars.
