Question

The Milky Way Galaxy has at least two hundred billion stars. Write this number in standard form. Make sure to add commas if the number needs them and don't add spaces to your answer.

Answer 1

Answer:

Looking up into the night sky, it's challenging enough for an amateur astronomer to count the number of naked-eye stars that are visible. With bigger telescopes, more stars become visible, making counting impossible because of the amount of time it would take. So how do astronomers figure out how many stars are in the universe?

The first sticky part is trying to define what "universe" means, said David Kornreich, an assistant professor at Ithaca College in New York State. He was the founder of the "Ask An Astronomer" service at Cornell University.

Answer 2

Two billion = 200,000,000,000
