Deneb's absolute magnitude is currently estimated as â8.4, placing it among the most luminous stars known, with an estimated luminosity nearly 200,000 times that of the Sun. This is towards the upper end of various published values over the last few decades.
VY Canis Majoris. Estimates of the star's radius range from around 1,500 to 2,000 times larger than the sun, if VY Canis Majoris was placed in the center of our solar system it would reach the orbit of Saturn! VY Canis Majoris is estimated to have a mass of around 20 to 40 times that of the sun.VY Canis Majoris is estimated to have surface temperatures of around 3,200C (5,800F). Measurements of the star's luminosity vary quite dramatically, from around 250,000 to 500,000 times as luminous as the sun.Y Canis Majoris is estimated to have a mass of around 20 to 40 times that of the sun.
