Antares vs Sun size comparison

Antares, also known as Alpha Scorpii is the fifteenth-brightest star in the night sky; the brightest star in the constellation of Scorpius, and is often referred to as “the heart of the scorpion”. It is a red giant. Its exact size remains uncertain, but, probably with a radius that is approximately 1 billion 228 million kilometers (883 times that of the Sun), it is one of largest stars in the Universe, and if placed in the center of the Solar System, its outer surface would lie between the orbits of Mars and Jupiter. The mass is calculated to be around 12 times that of the Sun. It is also nearing the end of its life. Once there is no more fuel left to burn, the star will collapse and explode into a supernova.
