VY Canis Majoris (abbreviated to VY CMa) is an extreme oxygen-rich red hypergiant or red supergiant (O-rich RHG or RSG) and pulsating variable star 1.2 kiloparsecs (3,900 light-years) from the Solar System in the slightly southern constellation of Canis Major.
Size comparison between the diameter of the Sun and VY Canis Majoris, a hypergiant which is among the largest known stars (possibly the largest in the Milky Way). K to M type spectra, the largest known stars by radius.
VY Canis Majoris (VY CMa) is a red hypergiant star located in the constellation Canis Major.One of the largest stars and also one of the most luminous of its type, it has a radius of approximately 1,420 ± 120 solar radii (equal to a diameter of 13.2 astronomical units, or about 1,976,640,000 km), and is situated about 1.2 kiloparsecs (3,900 light-years) from Earth.
VY Canis Majoris: 1,420 ± 120 [11] [12] [13] AD An extreme oxygen-rich red hypergiant that has experienced two dimming periods in the 20th century where the star became dimmer by up to 2.5 magnitudes. [14] Potentially the largest known star in the Milky Way. [12] There is a possilbility that this size might be a bit overestimated (on the order ...
Map showing various supernova candidates, most of which are within one kiloparsec from the Solar System. [1]This is a list of supernova candidates, or stars that are believed to soon become supernovae.
VY Canis Majoris: 2024 r=1,420 R ☉ Consistent with the upper limit for red supergiants of roughly 1,500 R ☉ based on the four largest stars measured in a survey, which is consistent with the current stellar evolutionary theory. [42] WOH G64 was the previous candidate [43] but was later found to be a smaller yellow hypergiant. [44] [45] [46]
Very Large Telescope image of the surroundings of the red hypergiant VY Canis Majoris. An OH/IR star is an asymptotic giant branch (AGB) or a red supergiant or hypergiant (RSG or RHG) star that shows strong OH maser emission and is unusually bright at near-infrared wavelengths.
