I love this show!

@ShadowHawkblack awesome :D

[davydekemp]

So the size of a star determens what happens to it when it dies?

[Socoolscienceshow]

@davydekemp For the most part yes, the bigger a star is the more fuel it will have and thus is why a bigger star can explode into a super nova. The less fuel you have the less power you will have and thus the chances of it exploding are extreamly low. How-ever theres always going to that one-two exception to the rule.

[Socoolscienceshow]

@moontalon22 yup thats the exact distance, if you calculate out all the AUs of the diamter of that star :)

[moontalon22]

@Socoolscienceshow

Oh ok cool. I think the number of the size varys alot of vy ca but mostly 2.800,000,000 yours must be exact though

[Socoolscienceshow]

@moontalon22 congraduationals thats very close, its diamter is 2,842,359,530kms. Im not sure how old the star is, but size alone doesnt always mean a star is old. When it dies off theres probably 2 things that will happen. It will go off in a hypernova and then form a black hole :)

[moontalon22]

@Socoolscienceshow VY ca also is exactly 2.800,000,100 km in diameter. but being a big star its also a very old one, and will explode in a Hypernova? correct me if im wrong.

[Socoolscienceshow]

@tfan0 Yup VY CMa is the largest star we know of currently and its known as a hypergiant star. If you place that star at the center of our solar system, it would stretch out to about as far as Saturn, which is about 9 AUs (astrononical units). If you placed one side of that star where our sun is, that star would stretch out to about as far as Uranus. So its just slightly smaller then our solar system. Uranus is 2 times as far from the sun then Saturn :D Everything in space is huge and far apart.

Hey do you know the star called VY Canis Majoris? that star is super super super super huge then our sun!! it's the size of our solar system! Like let's say a picture of VY canis majoris comparison with the sun. the sun will be the tiniest dot!
