Vy Canis Majoris is a colossal Red Hypergiant nestled within the constellation Canis Major, approximately 3,800 Light-Years from Earth. It is one of the largest and most luminous Stars known, with an estimated radius of about 1,420 times that of the Sun and a luminosity hundreds of thousands of times greater. This distant, burning heart in the cosmos is slowly shedding its mass through powerful Stellar Winds.
