VY Canis Majoris is a highly evolved star yet less than 10 million years (Myr) old. Some old writings envisaged the star as a very young protostar or a massive pre-main-sequence star with an age of only 1 Myr and typically a circumstellar disk. It has probably evolved from a hot, dense O9 main sequence star of 5–20 R☉ (solar radii). The star has evolved rapidly because of its high mass. The time spent to the red hypergiant phase is estimated to be between 100,000 and 500,000 years, … Web8 mrt. 2024 · VY Canis Majoris – in the direction to our constellation Canis Major the Greater Dog – is one of the largest stars known.

WebRed supergiants (RSGs) are stars with a supergiant luminosity class (Yerkes class I) of spectral type K or M. They are the largest stars in the universe in terms of volume, although they are not the most massive or luminous.
