And, yet, we do not think it is the biggest! Recent observations of a star called VY Canus Majoris show that it has a size between 600 and 2100 tims the size of our Sun! However, this star is only about 500,000 times brighter than our Sun and 30 or so times more massive than our Sun.
The biggest known by mass is R136a1 : see List of most massive stars. The largest known by volume is UY Scuti : see List of largest stars. R136a1 is in the nearby Large Magellanic Cloud , where it is also relatively easy to see things and be certain of their distance. UY Scuti is a mere 9,500 light-years away: our own galaxy is at least 100,000 light-years across.
