This staggering image shows how our sun - which is so big it accounts for 99.86% of the mass in the solar system - would look next to the biggest star in the universe. VY Canis Majoris is so large that it is impossible to even represent the earth in this picture as it would measure less than one thousandth of a single pixel.
So while solar radii would give us the âlargest star in universeâ by radius/circumference, it wouldnât give us the most massive star (solar mass), or the most powerful star (luminosity). With that in mind, letâs take a look at some of the largest stars, most massive stars, and most powerful stars in the known universe.
