it seems from what I've read that 3C 273 should probably be a lot bigger, because I have read that this quasar could be a hundred times brighter (bigger) than our milky way galaxy. so research this one more yourself. I would like to know more about this myself.
Scientists say that VY Canis Majoris is the biggest star we know so basically VY Canis Majoris is bigger than Kolob.
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
Canis Majoris is much bigger than our Sun. It is a red supergiant star approximately 1,000 times larger in diameter than the Sun.
R136a1 is the brightest known star. VY Canis Majoris. Its bolometric luminosity is estimated at 8.7 million times that of our Sun. VY Canis Majoris has a bolometric luminosity estimated at 450,000 that of the Sun, which is still very powerful. Bolometric luminosity refers to the entire radiation emitted at all wavelengths (not only visible light), so it is a measure of the power emitted by the star.
It's a Class M Hypergiant

As of today (2009) there is no star larger than VY Canis Majoris - a galaxy is larger than VY Canis Majoris though.
Canis Major is a constilation. Cy canis majoris is a star.
VY Canis Majoris (Not 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

Neither of them! The VY Canis Majoris is indeed bigger, but it isn't the biggest star in the Universe. The XZ Majoris Ceiphei is almost as big as the smallest Nebula, and it would take 10,000 years to orbit it in a passenger airplane. It is the biggest star in the Universe. So indeed the XZ Majoris Ceiphei is bigger than either the VY Canis Majoris or the NML Cygni. Comments: Estimating the sizes of these big stars is not easy and there are different answers in different places. For example, Wikipedia now gives NML Cygni as bigger than VY Canis Majoris. Also, I must admit I've never heard of "XZ Majoris Ceiphei". I know of the binary star XZ Cephei, but that's not the biggest star.
VY Canis Majoris is kinda beside Wezen(Delta Canis Majoris.) Find where it says VY
Canis Majoris is a constellation. VY Canis Majoris, the largest known star would fill the Solar System to the orbit of Saturn but would NOT fill the Solar System.
NO, VY Canis Majoris is the biggest star known to man . This star is also one of the most luminous star ever found . It is red hyper giant in the constellation Canis major . This star is 1800-2100 solar radii in radius and about 4900 light years away from the earth .
Canis Majoris is not a recognized astronomical term. It may be a confusion between two separate astronomical terms: "Canis Major" which is a constellation in the southern hemisphere, and "Canis Majoris" which may refer to a hypothetical supergiant star in the constellation Canis Major, although this specific term is not commonly used in astronomy.
