Recent estimates of the number of galaxies in the observable universe range from 200 billion (7011200000000000000â 2Ã1011) to 2 trillion (7012200000000000000â 2Ã1012) or more, containing more stars than all the grains of sand on planet Earth.
Averaging out the types of stars within our galaxy, this would produce an answer of about 100 billion stars in the galaxy. This is subject to change, however, depending on how many stars are bigger and smaller than our own sun.Also, other estimates say the Milky Way could have 200 billion stars or more.The number of galaxies is an astonishing number, however, as shown by some imaging experiments performed by the Hubble Space Telescope.bservable universe. Even if we narrow down the definition to the observable universe â what we can see â estimating the number of stars within it requires knowing just how big the universe is. The first complication is that the universe itself is expanding, and the second complication is that space-time is curved.
