@gigabecquerel As one may know from simple chemistry, Avogadro number allows us to calculate the number of molecules based on multiplying moles with 6.02×10²³, which means that there are around 48×10²³ water molecules, which means that there are 96×10²³ hydrogen atoms - since the formula for water is H²O.
As there is only one (which is less than 96×10²³) star in the entire Solar System for the foreseeable future; yes, it is higher than the number of stars in the Solar System.
