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.
The observable universe contains about 3 to 100 Ã 1022 stars (30 sextillion to a septillion stars), organized in more than 80 billion galaxies, which themselves form clusters and superclusters. Two approximate calculations give the number of atoms in the observable universe to be close to 1080.
