VY Canis Majoris is the largest star (in diameter) that we know of. Itâs in a class of star known as Red Hyper Giants. Itâs 1,420 times the sunâs radius and would take the worldâs fastest race car 2,600 years to circle it once. If you replaced our Sun with VY Canis Majoris, its surface would extend out beyond Saturn.
