At ~1,000 times the size of the Sun, Betelgeuse is an impressive star to be sure, but it's no match for UY Scuti, currently the largest star known with a diameter around 1,700 times that of the Sun. It's a crazy-bright candle, too, with a luminosity 340,000 times greater than the Sun.
...
You might think that such an enormous body would be easily visible with the naked eye, and it might be were it not 9,500 light-years away and squarely located in the Milky Way's Great Rift. After battling distance and dust, UY never gets brighter than magnitude +9 but can dip as low as +11.
