What is special about VY Canis Majoris?
VY Canis Majoris is one of the largest known stars by radius, luminosity, and mass in regards to typical red giants. VY Canis Majoris has been estimated to have around 17 solar masses, but its radius is a whopping 1.420 times greater than our sun’s. The hypergiant is also around 270.000 times brighter than our sun.
What will VY Canis Majoris become?
VY Canis Major is predicted to explode as a supernova within the next 100,000 years. If it does explode, we would see it brighten considerably even though it is quite some distance away from us. Its distance (3,900 light-years) is greater than that of Betelgeuse, which is only about 640 light-years away.
Is VY Canis Majoris a red giant?
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 1.2 kiloparsecs (3,900 light-years) from the Solar System in the slightly southern constellation of Canis Major. It is about 17±8 times the mass of the Sun ( M ☉).
Will Canis Majoris become a black hole?
In a regular supernova this extremely dense ball could become a neutron star or a pulsar, but the unusually high mass of VY Canis Majoris (or a similar hypergiant) would result in the formation of a rogue stellar-mass black hole… with an explosion of gamma rays that has the ability to wipe out any cellular life in …
What would happen if Uy scuti exploded?
So the force of 100 stars exploding would obliterate everything nearby. Even if Earth was far enough away to survive the blast, without the star, there would be no heat and no light, and life could not survive on Earth without them.
