Is Antares bigger than Betelgeuse?
Its volume is 1,000^3, or 1billion times larger. Yet it’s only 10 times heavier, making the mean density 1/100,000,000 that of the sun (and about the same density relative to water.)
Where is Antares now?

Is Betelgeuse a red giant?
This is because Betelgeuse is a red giant star. To appreciate Betelgeuse’s reddish colour you can compare it with another star in Orion. This star is called Rigel and it has a bluish tinge. You can find it by looking to the lower-right of the Belt.
Is UY Scuti a Hypergiant?
The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun.
Will Antares explode?
Antares, like the similarly sized red supergiant Betelgeuse in the constellation Orion, will almost certainly explode as a supernova, possibly in the next ten thousand years. For a few months, the Antares supernova could be as bright as the full moon and be visible in daytime.
Is Antares a dead star?
Antares is also about half of the surface temperature of the Sun. Unfortunately, Antares is an old and dying star (as are all red giants). One day, the red star will no longer be visible to us after it transforms into a new celestial object.
Is Antares going to explode?
As a supergiant, Antares is considered close to its end. When it has used up its hydrogen fuel, it will collapse and explode as a supernova (sometime in the next 10,000 years).
