How many stars are there?

Answer 1

In milky way there are nearly 140 BILLION.
this is actually calculated by knowing the distance of the sun from the nucleus of our galaxy and its radius.
Actually there are billions of galaxies, each containing billions of stars

Answer 2

Like the number of grains of sand on the beach or angels that can dance on the head of a pin, the number of stars in the sky remains a great unknown. Discussing the number of stars in the Milky Way alone, astronomer William Keel, writing for the sci.astro Galaxies FAQ, claims that there are "about as many as the number of hamburgers sold by McDonald's."
Then he elaborates. The usual way to determine the number of stars in the universe is to consider how many stars there are in the Milky Way, and then to multiply that number by our best guesstimate at the number of galaxies in the universe. This FAQ suggests there are probably about 400 billion stars in the Milky Way, although "a 50% error either way is quite plausible." As for the number of galaxies in the universe, well that's a whole separate mathematical puzzle.

Other star enumerators we located on the Web offer numbers ranging from more than 200 billion stars in our galaxy to 3 thousand million billion stars (3 followed by 16 zeroes), in the universe. NASA alleges there are zillions of uncountable stars.

From a recent astronomy news article on CNN.com, we learned about the Sloan Digital Sky Survey, an ambitious astronomy project currently mapping the night sky, to determine the "positions and absolute brightnesses of more than 100 million celestial objects."

Answer 3

On an average clear night , one can see only a few thousand stars in the night sky.Though with a normal telescope around 10,000 stars can be counted.
Actually , there are 100,000,000,000 stars in the milky way alone, which is a average sized galaxy.It is estimated that
100,000,000,000 such galaxies are present, so that makes the total no. of stars to
10,000,000,000,000,000,000,000 .

Answer 4

There are so many stars in the universe that we could not count them all. About 7000 stars can be seen from the earth without a telescope

Answer 5

400 billion stars in the Milky Way Galaxy. 3 thousand million billion stars are there in the space as a whole...

Answer 6

As many as you'd like to guess

Answer 7

there are billions of stars in the sky . even if we count also another star will visible after few minutes like this stars visible to us are not real count there are so many stars that are not visible now it will be visible after few day or few months are few years .

Answer 8

Uncounted trillions and trillions. As far as how many of them you can actually see with your naked eye in the darkest possible location? About 3000 at any one time. (Meaning there is a total of about 6000 stars visible to the naked eye under ideal conditions.)

Answer 9

This is a ever changing number as birth & death of stars are going on. So do not expect any exact count.

There are around 70,000 million million million visible.

Answer 10

Something on the order of a billion trillion. Nobody has anything like an exact count.
