Carl Sagan used to say, "there are 100 billion galaxies each with 100 billion suns."

100 billion x 100 billion = 1022

Although today, many scientists estimate that number to be even larger still.

There is no way of knowing as our understanding of the universe is still very small.

It's like asking how many grains of sand there are on the Earth surface, it would be impossible to give an exact number. Funny enough, some say that the number of stars actually exceeds the number of grains of sand!
