How many stars are in the visible universe?

It is impossible to count the number of stars in the Milky Way, which is estimated to be between 200 and 400 billion, because of dust and gas clouds. The number of stars in the universe depends on the power of your telescope.

With an estimated 100 billion galaxies in the visible universe, and billions to trillions of stars in each galaxy, the total estimated number of stars in the visible universe is approximately 100 billion trillion (100,000,000,000,000,000,000,000), or one followed by twenty-three zeros.

The estimated number of stars in the visible universe is roughly around 100 billion galaxies, with each galaxy containing an average of around 100 billion stars. Therefore, the total number of stars in the visible universe is estimated to be approximately 10^24 stars.

Estimates suggest there are approximately 100 billion to 200 billion galaxies in the observable universe, each containing hundreds of billions of stars. This puts the estimated number of stars in the visible universe at around 10^24 (1 septillion) to 10^25 (10 septillion) stars.
