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.

What does CY or VY signify?
It means they are variable stars and are named using a variation on the Bayer designation format of an identifying label combined with theLatin genitive of the name of the constellation in which the star lies. So: VY Canis Majoris = VY (Variable) Canis Majoris (Constellation) YZ Ceti = YZ (Variable) Cetus (Constellation) See related link for more information.
Do you have to die if you fall into a black hole?
A black hole is more powerful than anything in the Universe except an XZ Majoris Ceiphei, so indeed you would have to die if you fell into a black hole for sure; except if you ARE an XZ Majoris Ceiphei.
What is a bright giant?
A bright giant is a class of star that don't quite make it into the supergiant class but are much more luminous than giants.Eg. Epsilon Canis Majoris (Adhara): a blue-white (B-type) bright giant
What does VY in VY Canis Majoris mean?
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]
How do astronomers think the sun started?
Astronomers think the Sun started out like all other stars: A star birth nebula, a massive stellar gas cloud that growing stars absorb with their gravity to fuel the nuclear reaction in their cores. So basically, the Sun is a giant swirling ball of gas, but more specifically, the Sun is a star in the classification of a Yellow Dwarf, which really isn't that large of a star, as a matter of fact, compared to VY Canis Majoris, a star in the classification of a red giant, and the biggest known star in the universe, the Sun is approximately 2,800 times SMALLER than VY Canis Majoris.
Which star is more luminous R136a1 or VY Canis Majoris?
R136a1 is the most luminous at about 8,700,000 times more than the Sun. VY Canis Majoris is only 450,000 times more luminous than our Sun.
Which star is bigger VV Cephei A or 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
Where is the constellation canis major located?
Alpha Canis Majoris - Sirius A & B (a double star system)Beta Canis Majoris - Murzim (also Mirzam, Mirza, among others)Gamma Canis Majoris - Muliphen (also Muliphein)Delta Canis Majoris - Wezen (also Wesen)Epsilon Canis Majoris - Adara (also Adhara)Zeta Canis Majoris - Furud (also Phurud)Eta Canis Majoris - Aludra
How far is Adara?
Epsilon Canis Majoris (Adara), is the second brightest star in the constellation Canis Major.It is located about 420 light years from us.See related link for more information
What do VY Canis Majoris and the moon have in common?
They are both spherically shaped. Other than that they have little in common. VY Canis Majoris is a star so big that if it was where the Sun is, we would be inside it and so would Mars. More spectacularly, so would Jupiter. Saturn would be frying.
Is betelgeuse the biggest star you know of?
No. The biggest star ever discovered is the VY Canis Majoris, a red hypergiant with a radius of easily 2000 times bigger than that of the Sun. That is more than twice the radius of Betelgeuse. Also, the mass of VY Canis Majoris is around twice that of Betelgeuse.
If VY Canis Majoris was earth would it support 100 billion people or more?
No. VY Canis Majoris is a red "hypergiant" star. It would not support life at all. If the Sun were somehow replaced by VY Canis Majoris, the Earth would be instantly vaporized. You might be thinking "but what if it was a planet instead of a star," but the notion of a planet that large is ludicrous; anything that big would instantly collapse into a black hole without heat and radiation pressure from internal fusion to oppose its own gravity.
