Table of Contents
VY Canis Majoris is an extreme oxygen-rich red hypergiant or red supergiant and pulsating variable star 1.2 kiloparsecs from the solar system in the slightly southern constellation of Canis Major.
Information
Radius :- 987.89 million km
Distance to Earth :- 4,892 light years
Mass :- 3.381 × 10^31 kg (17 M☉)
Surface temperature :- 3,490 K
Coordinates :- RA 7h 22m 58s | Dec -25° 46′ 3″
Age :- 8.2 Myr
Constellation :- Canis Major

Density
5.33 to 8.38 mg/m3
Despite the mass and very large size (though some estimates give smaller sizes), VY CMa has an average density of 5.33 to 8.38 mg/m3 (0.00000533 to 0.00000838 kg/m3). It is over 100,000 times less dense than Earth's atmosphere at sea level (1.2 kg/m3).
Orbit
VY Canis Majoris's diameter is around 1.750 times greater than the sun's at approximately 1.5 billion miles / 2.4 billion kilometers. If this hypergiant would be placed in the center of the solar system, its surface would extend beyond the orbit of Jupiter, and some estimate it would extend up to the orbit of Saturn.
