Until a short time ago it was UY Scuti that used to be considered the largest star known to mankind for a long while. Located 9,500 light years away from the Sun, the star is so staggeringly enormous that it would cover areas beyond Jupiter’s orbit were it placed in the centre of the Solar System. Its radius may reach 1,900 those of the Sun and its volume may be over 5 bln times that of the Sun. But recently it was beaten by Stephenson 2-18 which is now the largest star in the parts of the universe studied by us.
