Yes, relatively it is a fairly cold star. Our sun is nearly 6000 K and VY Canis Majoris is about 3000 K. Still much hotter than most would like it, but as I said, relatively 'cold'.

The name "Vy Canis Majoris" comes from the star's location in the constellation Canis Major and its classification as a "variable" star. "Vy" is simply a designation for variable stars while "Canis Majoris" indicates its location in the constellation.
VY Canis Majoris is probably bigger. VV Cephei A is between 800 and 950 times the diameter of our sun. VY Canis Majoris is 900 to 1050 times the diameter of our sun. As you can see, there is some overlap in the numbers, so it is possible VV Cephei A is actually the larger star, though more likely VY Canis Majoris is the biggest.Also if u see a video of biggest star it is shown that VV cephei A is actually smaller than Vy canis majoris
