How many stars are there in the known universe?

David Kornreich provided an approximate count of stars.

However, if you do this mathematically, you can get a number that ranges from 10 sextillion to 80 sextillion stars by multiplying the average number of stars (which can vary from 100 to 400 billion) in a galaxy by the number of galaxies (which can vary from 100 to 200 billion) in the observable universe.

However, you have to increase those figures by an order of magnitude because the most recent estimate indicates that there are ten times more galaxies in the universe.

The Milky Way defines the average galaxy, and we don't even know the exact number of stars in our own galaxy, so all of this is just a very rough estimate.

I hope it is useful.

The exact number of stars in the known universe is not precisely known, but estimates suggest there are around 100 billion to 200 billion galaxies, each potentially containing millions or billions of stars.
