So, even though we cannot actually count the number of stars in the galaxy, we can estimate the number of stars in the galaxy as roughly 100 billion (100,000,000,000). It turns out that there are many more stars with mass less than the mass of the Sun than with mass more than the mass of the Sun. So, it all works out right.
This varies extremely from galaxy to galaxy, from tiny galaxies with 10 million stars, to huge ones with 1000 billion stars. The average is somewhere between 100 and 1000 bi â¦ llions. An exact number is hard to give, as we don't even know the number of stars in our own galaxy (between 100 and 400 billions).And there are 170 billion galaxies in the observable universe, so counting the average number of stars could take a while.he estimate for the number of stars is about 100 billion stars-plus or minus 50 billion. 2 people found this useful. 1  Easy to Use Pregnancy Due Date Calculators When you are pregnant, the question on everyone's mind is when the baby is due.
