GENERAL KNOWLEDGE

Detailed explanation-1: -There are different models for estimating the number of stars in the Milky Way and the answers they give differ depending on what is used as the average mass of a star. The most common answer seems to be that there are 100 billion stars in the Milky Way on the low-end and 400 billion on the high end.

Detailed explanation-2: -Astronomers estimate there are about 100 thousand million stars in the Milky Way alone. Outside that, there are millions upon millions of other galaxies also!

Detailed explanation-3: -Our Milky Way galaxy is just one of the billions of galaxies in the universe. Within it, there are at least 100 billion stars, and on average, each star has at least one planet orbiting it. This means there are potentially thousands of planetary systems like our solar system within the galaxy!

Detailed explanation-4: -The Milky Way is the galaxy in which our Solar System lives. There are more than 200 billion stars in our spiral galaxy, and our Sun is just one of them. Even if you traveled at the speed of light, it would take you about 100, 000 years to get across the Milky Way.
