AZ Cephei
From EverybodyWiki Bios & Wiki
AZ Cephei is an M2 supergiant. It is among the largest stars, with an effective solar radius of over 800.[1] For the first estimate, the star's photosphere would engulf the outer limits of the asteroid belt, and at its largest size it would be nearing the orbit of Saturn.
