Question

How many stars are there

Answer 1

No one really knows, there's way too many to count.
but id say around 100 octillion stars.

Answer 2

"Kornreich used a very rough estimate of 10 trillion galaxies in the universe. Multiplying that by the Milky Way's estimated 100 billion stars results in a large number indeed: 1,000,000,000,000,000,000,000,000 stars, or a "1" with 24 zeros after it".
