How many stars stars are in our galaxy?
Estimated at 200-400 billion stars.
How many stars within 50 light years from earth?
According to SIMBAD, ~970. But there's a lot of stars within 50 light years whose distances aren't known. There's quite a few stars within 50 light years. To get a good estimate, we should consider how many stars within 20 light years, and go from there. The nearest 25 light years are really well catalogued, and the current census is 200 stars. Now, through knowledge of Geometry, one can say that if you multiply the radius of a 3D shape by a number, x, the volume will increase by the x^3. Why 3? because it's a 3D shape. So we double our sphere from 25 to 50 light years. So thus the volume increases by 2^3 = 8 times! So there are 8 times as many stars within 50 light years as there are within 25 light years. 200 * 8 = 1,600 stars (estimate).

How many stars are there?
There are an estimated 100 to 200 billion galaxies.Scientists estimate that our Galaxy (The Milky Way) contains 200 to 400 billion stars.So taking a conservative number of 100 billion stars per galaxy, gives an approximate total of 10,000,000,000,000,000,000,000 stars. (which is 10 sextillion)It is unknown. The Milky Way galaxy contains an estimated 200 billion stars and there are an estimated 100 billion galaxies in the observable universe. However, our galaxy is significantly larger than most. That said, if we assume the average galaxy has 10 billion stars then we arrive at an estimate of 1,000 billion billion stars, or about 1 sextillion stars.

How many people in a study of people?
Statistically speaking, studies show that a random sample of 200 people yields about the same data for ANY larger number of people, such as 5 million. Therefore, the minimum number of people surveyed in a scientific study should be 200.

What is a huge system containing billions of years?
if by years you mean stars... our own galaxy contained from 200 to 400 billion stars. Years are a measurement of time, a human way of gauging the passage of time. It is intangible and thus unable to be contained within anything.
When was the exact month and day Number the Stars by Lois Lowry came out?
