VY Canis Majoris is a high-luminosity M star with an effective temperature of about 3,500 K, placing it at the upper-right hand corner of the HertzsprungâRussell diagram and meaning it is a highly evolved star. During its main sequence, it would have been an O-type star with a mass of 15 to 35 Mâ .t has an average density of 5 to 10 mg/m 3. If placed at the center of the Solar System, VY Canis Majoris's surface would extend beyond the orbit of Jupiter, although there is still considerable variation in estimates of the radius.
