Canis Majoris can refer to any number of stars which, as seen from Earth, reside within the Canis Major constellation.
Scientists say that VY Canis Majoris is the biggest star we know so basically VY Canis Majoris is bigger than Kolob.
As far as mass goes, R136a1 beats out VY Canis Majoris by 253 solar masses (265 solar masses for R136a1 vs Canis Majoris' 30). However, VY Canis Majoris beats out R136a1 in radius by about 1,385 solar radii (Canis Majoris is 1,420 solar radii vs R136a1's ~35).
Vy Canis Majoris is a red hypergiant star that is near the end of its life cycle. It is expected to eventually explode in a supernova event, but precisely when this will happen is uncertain. It could be in the near future or it could be thousands of years from now.
VY Canis Majoris has an absolute magnitude of -9.4.
Yes. It is way bigger. The VY Canis Majoris is known to be 1,000,000,000 times the size of the Sun. It's so big that on a scale between the 2 the VY Canis Majoris would almost be a complete rectangle compared to the Sun (and the Sun is as small as a few pixels). The star would reach the top of the screen. Winner: VY Canis Majoris
Never.VY Canis Majoris - WAS a blue supergiant. It is now a red hypergiant and will "soon" become a massive supernova.
VY Canis Majoris is kinda beside Wezen(Delta Canis Majoris.) Find where it says VY
Canis Major is a constilation. Cy canis majoris is a star.
When the canis majoris explodes, it will create a supernova of over 30000 degrees. A supernova is a huge explosion of fire. After the supernova, a black hole will form. Black holes form when a star explodes. But it cant just be a star. It has to be a star 10x greater then our sun. The canis majoris is way bigger then just 10x. So when it explodes it will create a black hole much bigger then normal size.
VY Canis Majoris (Not Canis Majoris)
VY Canis Majoris has an absolute magnitude of -9.4.
As of today (2009) there is no star larger than VY Canis Majoris - a galaxy is larger than VY Canis Majoris though.

VY Canis Majoris is about 4,900 light years from earth.
Scientists say that VY Canis Majoris is the biggest star we know so basically VY Canis Majoris is bigger than Kolob.
As far as mass goes, R136a1 beats out VY Canis Majoris by 253 solar masses (265 solar masses for R136a1 vs Canis Majoris' 30). However, VY Canis Majoris beats out R136a1 in radius by about 1,385 solar radii (Canis Majoris is 1,420 solar radii vs R136a1's ~35).
The biggest star - VY Canis Majoris IS in a red supergiant phase and will explode as a massive supernova.
