You can't see it with the "naked eye", but binoculars or a small telescope should show it.
In fact it is a very bright star, but it's quite along way from Earth.
Also it's a variable star, so its brightness varies.
VY Canis Majoris has a radius about 2,100 times that of the Sun. This means that about 9 billion Suns could fit inside it. See related link for a picture of the difference in size.
The general tendency is that stars are more concentrated towards the center. However, there are also star clusters (globular clusters), scattered all over the galaxy, that contain - in some cases - over a million stars in a fairly small region.
From Wikipedia: "...between 1800 and 2100 solar radii..." Note that this means the radius is not known precisely. Assuming 1800 solar radii. Also, the Sun has 109 times the radius (or diameter) of Earth. That results in this star having 1800 x 109 = about 200,000 times Earth's diameter. Take the cube of that, and you get a volume that is 7,500,000,000,000,000 (7.5 x 1015) times that of Earth. With the higher number (2100), you get 12,000,000,000,000,000 (12 x 1015). A few other sources say it is closer to 11,666,192,832,000,000 Earths!
The answer is your mom Voliet8910 says: The brightest star Sirius is in it.
"Great dog" and "Lesser dog". Except in Latin, so it's Canis Major and Canis Minor.
VY Canis Majoris is kinda beside Wezen(Delta Canis Majoris.) Find where it says VY
VY Canis Majoris has an absolute magnitude of -9.4.
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.

VY Canis Majoris (Not Canis Majoris)
9,261,000,000 (9.2) Billion sun can fit in VY Canis Majoris.

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
