well, if you are referring " how does the mass of the sun compare to the rest of solar system"
well, the sun gravitational pull holds the solar system together. sun is very gigantic, we can prove that, it is very massive at all, because sun is near from earth, although if you're comparing to the rest of solar system such as star, and other heavenly bodies , Sun is just an average star ,stars are very huge, very massive, the smallest star discovered is about the size of the sun, sun belongs to the thousands billions of stars in our galaxy, which is just one of more than billion galaxies in the observable universe, when you observed at the night sky , stars are very small , because stars are very distant away from earth about a million thousand distance, we can see about their apparent brightness at all and some stars are very brighter than the sun.
