      Scientists have estimated any where between 300-400 millions stars in the Milky Way which is an average sized galaxy. Most of the stars are about the size of the sun in our Milky Way…

      But… apparently the scientists currently think there may be 100-200 BILLION galaxies in the universe… which means another 200 billion Milky Ways, which means how many stars if all galaxies were like the Milky Way?

      4 000 000 x 2 000 000 000 000 =

      8 000 000 000 000 000 000 stars

      But some galaxies are even bigger which means there are probably a lot more stars than this!
