Hmm... not sure if it's really true. But it IS interesting...

Scroll from one image to another to see the comparison. Enjoy.
Hmm... I never notice that Anatres is really that BIG!!! The diameter of Antares is around 700 times of our Sun diameter... our Sun diameter is around 1,400,000km, so Antares diameter will be around 980,000,000km!!! Basically, it diameter is slightly larger than distance from Sun to Jupiter!!I don't think antares is that much bigger than the sun though...I could be wrong of course.
