How about size. I think we first need to get a sense of size so we can really understand how big this star is. Our Sun is 870,000 miles across (or 1.4 million km). We could probaly fit the Earth inside the Sun 1 million times. The biggest star VY Canis Majoris is so big the Sun would fit inside this about 2100 times. Traveling. If you where to fly a plane around the world it would take about 40-50 hours (depending on fuel stops etc). Now, if you where to fly around the biggest star itâs believed it could take 1100 years!!
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.
