V y canis majoris where is

As such, they emit energy at a very fast rate. Thus, hypergiants only last for a few million years. Compare that to the Sun and similar stars that can keep on burning up to 10 billion years. VY Canis Majoris a. VY CMa is about 4, light years from the Earth. This value, however, is just a rough estimate because it is too far for parallax to be used. VY Canis Majoris has been estimated to have around 17 solar masses, and it is believed that it's lost more than half its mass.

If this hypergiant would be placed in the center of the solar system , its surface would extend beyond the orbit of Jupiter , and some estimate it would extend up to the orbit of Saturn. It is an extreme oxygen-rich and pulsating variable star. It has an apparent magnitude that varies from 6. This hypergiant is losing its mass to a rate of around 30 times the mass of Earth every single year.

Much of this material has taken the shape of a cloud of dust and gas around the star. It is speculated that the hypergiant has already lost more than half of its mass. The hypergiant is around VY Canis Majoris is cooler than our sun, with an estimated surface temperature of around 3. Our Sun has around 5. VY Canis Majoris has an average density of 5. It is bright enough to be observed with a pair of regular binoculars.

Massive ejections of material which correspond to its very deep fading, which is probably due to dust that temporarily blocks light from the star.

In a previous study, Professor Humphreys and colleagues determined when these large structures were ejected from the star. They found dates ranging over the past several hundred years, some as recently as the past to years. In a new study, they resolved features much closer to the star that may be less than a century old.
