UY Scuti
One of the largest known stars by radius/Stars
UY Scuti is a red supergiant and pulsating variable star in the constellation Scutum. It is one of the largest stars ever measured by radius, with estimates suggesting it could engulf the orbit of Jupiter if placed at the centre of our solar system. Despite its immense size, its mass is relatively modest for a supergiant.
