V354 Cephei is a red supergiant star located within the Milky Way. It is an irregular variable located approximately 9000 light-years away from our Sun and is currently considered one of the largest known stars with a radius estimate of 690-1520 times that of the Sun or 1060000000 km at its greatest extent. Assuming the upper size estimate is correct if it were placed in the center of our Solar System it would extend to 7 AU between the orbits of Jupiter and Saturn.
