VY Canis Majoris is a remote red hypergiant located approximately 3,800 light-years away from Earth. Use, Smithsonian Astrophysical Observatory. Bright deep sky objects in the constellation include the open clusters Messier 41, NGC 2360 (Caroline’s Cluster) and NGC 2362 (the Tau Canis Majoris Cluster), the Canis Major Dwarf, the closest neighbouring galaxy to Earth, … %�쏢 The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative The luminosity of the famous red supergiant VY CMa ( L = 4 5 x 105 L ) is well-determined from its spectral energy distribution and distance, and places it near the empirical upper luminosity limit for cool hypergiants. It has the Luminosity of 178,000 Suns and the radius of 1,420 Suns, which corresponds to a volume of 3 billion Suns. In contrast, its surface temperature is fundamentally ill-defined. VY Canis Majoris (VY CMa) is a reid hypergiant in the constellation Canis Major.It is ane o the lairgest kent starns bi radius an an aa ane o the maist luminous o its type.It is approximately 1,420 ± 120 solar radii (equal tae 6.6 astronomical units, sicweys a diameter aboot 1,975,000,000 kilometres (1.227×109 mi)), an aboot 1.2 kiloparsecs (3,900 light-years) distant frae Yird.VY CMa is a single starn categorized … stream Rho … Implications for its location on the HR Diagram and its apparent size are discussed. Implications for … Title: VY Canis Majoris: The Astrophysical Basis of Its Luminosity. The luminosity of the famous red supergiant VY CMa (L ~ 4 - 5 x 10e5 Lsun) is well-determined from its spectral energy distribution and distance, and places it near the empirical upper luminosity limit for cool hypergiants. Both contradict a recent paper by Massey, Levesque and Plez (2006). A hypothetical object travelling at the speed of light would take 6 hours to travel around the star's circumference. Notice, Smithsonian Terms of In contrast, its surface temperature is fundamentally ill-defined. Implications for its location on the HR Diagram and its apparent size are discussed. It is one of largest stars known (sometimes described as the largest known) [64] and is also one of most luminous with a radius varying from 1,420 to 2,200 times the Sun's radius, and a luminosity around 300,000 times greater than the Sun.
