G is the gravitational constant and it’s equal to about 6.67 * 10^-11. M is the mass of the star, which according to your link is not known exactly but estimated to be about 30 to 40 solar masses.

VY Canis Majoris (abbreviated to VY CMa) is an extreme oxygen-rich (O-rich) red hypergiant (RHG) or red supergiant (RSG) and pulsating variable star located at 1.2 kiloparsecs (3,900 ly) away from Earth in the constellation of Canis Major.It is one of the largest known stars by radius, and is also one of the most luminous and massive red supergiants, as well as one of the most luminous stars …
11/3/2020 · VY Canis Majoris has an apparent magnitude that varies from 6.5 to 9.6, and it is also a fast-spinning star having a rotational velocity of around 300 km / 186.4 mi per second. This star is quite young, being only 8.2 million years old, however, it will not live for long.
VY Canis Majoris | Constellation Guide, VY Canis Majoris | Facts, Information, History & Definition, VY Canis Majoris | Constellation Guide, VY Canis Majoris | Facts, Information, History & Definition, IuIticolor photometric observations of VY C a between 0.36 and 22 have been interpreted in terms of a model consisting of a dust disk surrounding and hiding a star with an energy distribution like that of a1 Her. The emitted continuous spectrum was separated into two components: one scattered in the disk, and another due to thermal emission by solid particles. The radial T(r) distribution in …
To investigate the peculiar line shape of the ground-state SiO emission from VY CMa, the (Si-28)O, (Si-29)O, and (Si-30)O emission profiles were observed. Strong narrow emission in the (Si-29)O spectrum was detected, twice the strength of the (Si-28)O narrow emission. No (Si-30)O emission was detected at the limit of the noise. The observations are difficult to interpret in terms of a …
If anything, the planet would simply fall into CM, considering it’s monstrous size and (probably) low escape velocity . $endgroup$ – Youstay Igo Jun 18 ’16 at 17:25 $begingroup$ What does density have to do with it? $endgroup$ – HDE 226868 ? Jun 18 ’16 at 17:26, The other two stars were AH Scorpii and KW Sagittarii, also red supergiants with a luminosity over 100,000 times that of the Sun and among the biggest stars known. Following the survey, UY Scuti was named the largest known star, leaving behind VY Canis Majoris , NML Cygni and Betelgeuse, which had all previously carried the title.
