The Largest Star in the Milky Way Galaxy

The variable hypergiant UY Scuti is the largest star in the Milky Way Galaxy. 5 billion Suns could fit inside it!

UY Scuti is a massive red supergiant star found in the constellation Scutum. Its size is mind-blowing, about 1,708 times bigger than our Sun! It’s not too far away from us, just 9,500 lightyears.

If it took the Sun’s place, its surface would extend past Jupiter’s orbit. It’s so huge that its radius, about 1,189,348,720 km, is even larger than Saturn’s orbit.
