VX Sagittarii is a red supergiant star.

A red supergiant star is a larger and brighter type of red giant star. Red supergiants are often variable stars and are between 200 to 2,000 times bigger than the Sun. An example of a red supergiant star is Antares. 119 Tauri, Betelgeuse, Mu Cephei, and VV Cephei are other famous examples of red supergiants. Most red supergiant stars explode as supernovae, but some of the brightest become Wolf-Rayet stars before exploding.[1]
