List of the largest known stars in the Milky WayTemplate:Efn
Star name Solar radii
(Sun = 1)
MethodTemplate:Efn Notes
Orbit of Saturn 2,0472,049.9[1]Template:Efn Reported for reference
UY Scuti 1,708±192[2] AD The radius of UY Sct is more extreme than what current stellar evolution models predict. One paper mentions this extremity, and the reason for it is not yet clear.[3]
V354 Cephei 1,520±304[4] L/Teff
The above radii are larger than what stellar evolution theory predicts, and are thus potentially unreliable
Theoretical limit of star size (Milky Way) ~1,500[4] This value comes from the rough average radii of the three largest stars studied in the paper. It is consistent with the largest possible stellar radii predicted from the current evolutionary theory, and it is believed that stars above this radius would be too unstable and simply do not form.[4]
