How many stars are in nasa database

There isn’t a way to perfectly make sure how exactly many stars are there in the sky. So how many stars are there in the Universe? It is easy to ask this question, but difficult for scientists to give a fair answer! No one would try to count stars individually, instead they measure integrated quantities like the number and luminosity of galaxies. Astronomers estimate there are about 100 thousand million stars.

The National Aeronautics and Space Administration (NASA) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program as well as aeronautics and aerospace research.
