The VY doesn't stand for anything.
Before there were telescopes, stars were giving meaningful names, but once the telescope came into play, more stars were discovered than names could be found for. So a number of star catalogues were developed [See related link] to try and get around this problem.
VY is just an entry in the Bayer Catalogue for variable stars [See related link]
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 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
A day on VY Canis Majoris is estimated to be around 1.5 Earth years due to its slow rotation.
VY Canis Majoris has an absolute magnitude of -9.4.
VY Canis Majoris is kinda beside Wezen(Delta Canis Majoris.) Find where it says VY
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.
VY Canis Majoris (Not Canis Majoris)

9,261,000,000 (9.2) Billion sun can fit in VY Canis Majoris.
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 (VY CMa)
Yes, the largest known star is VY Canis Majoris which is about 2,100 times larger than our Sun which would mean 9,261,000,000 Suns would fit inside.
