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 … A hypothetical object travelling at the speed of light would take 6 hours to travel around the star's circumference. 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.

Humphreys (Submitted on 13 Oct 2006) Abstract: 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. 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. VY Canis Majoris is one of the largest known stars.
