Sh2-310 is also host to the stars Tau Canis Majoris [35] which is the brightest member of NGC 2362, [36] UW Canis Majoris and HD 58011 [35] which along with VY Canis Majoris [37] are thought to be probable sources of ionization of gases in Sh2-310. [35] Sh2-310 itself is located on the outer edge of the Orion Arm of the Milky Way. [32]
English: Size comparison of evolved red supergiant star Stephenson 2-18, extreme red hypergiant star VY Canis Majoris and luminous red supergiant star UY Scuti. Bahasa Indonesia: Perbandingan ukuran bintang super raksasa merah berevolusi Stephenson 2-18, bintang hypergiant merah ekstrim VY Canis Majoris dan bintang super raksasa merah bercahaya ...
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. [12] There is a possilbility that this size might be a bit overestimated (on the order of 1 sigma).
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.
