• How many stars exist? There are billions of stars in our galaxy. There are billions of galaxies that we can see. Some are larger than ours some are smaller. This adds up to billions and billions and billions of stars. How many planets? We have no way of knowing. See my answer to this question ( for why. Is there a fixed ratio between them? Without knowing how many planets there are and how they are distributed, we can't answer this question either. ************** "Anonymous: actually with the naked eye humans can only see about 4000 stars, so by saying that we can see billions os stars is incorrect" The question said nothing about limits to what we can see with the naked eye. So, I didn't limit my answer to just those objects that we can see with the naked eye. My answer includes those objects that can be seen with the various types of telescopes as well.
  • lol thats impossible to detremon, we cant even count all the ones in the range of our lil big bang vicinty, theres just to many, prtically infinite amount, plus their being made and destroyed constenly, ud be talking at least trillions
  • I have heard everything from 100 million to 70 thousand million million million one really has any idea.
  • For a wild guess, i shall use the figures used to calculate the amount of bytes in a terabyte. On a ratio of 1,099,511,627,776 bytes = 1024^4 or 2^40 bytes. Taking a figure that there MAY (assuming particulars) be 2^40 stars in this particular galaxy. Take that and multiply the variable of galaxies (assuming that galaxies have an average number of stars) (X) and multiply that amount by 2^40: 2^40X To find a rough estimate, one would simply need to figure the amount of galaxies. To find an exact number though, is a hair-breadth away from impossible. EDIT: I forgot to mention this, stars are constantly dying and being born at an uncalculatable rate so that's another wrench in this mathematical equation. You might alter this by adding the decline(Z) and birth of new stars (Y) 2^40X+(Y-Z)
  • I'm happy that there is a warm one nearby. The total is incalculable since the universe is infinite. But, the last time I checked, they were all still in place (apparently), allowing for the relative slow speed of light.
  • Enough so we'll never stop wondering what they are.
  • My estimation would be the amount of how many grains of sand are on a beach, multiplied by the number one, followed by one hundred zeros. (aka a google)
