Canis Majoris, also known as VY Canis Majoris, is a red hypergiant star with an estimated surface temperature of around 3,500 to 3,600 Kelvin. This relatively low temperature contributes to its reddish appearance. As one of the largest known stars, it has a radius approximately 1,400 times that of the Sun.

Canis Majoris is not a recognized astronomical term. It may be a confusion between two separate astronomical terms: "Canis Major" which is a constellation in the southern hemisphere, and "Canis Majoris" which may refer to a hypothetical supergiant star in the constellation Canis Major, although this specific term is not commonly used in astronomy.
the first known record of vy canis majoris is in the star catalogue of Jerome Lalande on March 7,1801
