'''V354 Cephei''' is a [[Supergiant star]] in the [[constellation]] of [[Cepheus]].<ref name=zmescience>{{cite web|url=https://www.zmescience.com/science/largest-stars-feature/|title=The largest stars in the Universe (that we’ve found so far)|accessdate=July 06, 2020|publisher=zemscience.com|author=Janet Mason|date=Janurary 16, 2020}}</ref> It is one of the largest stars known, thought to have a radius over 1,500 times greater than the [[Sun]]'s.

V354 Cephei is located 9,000 [[light year]]s from [[Earth]]<ref name=universeguide/> The enormous distance means it shines with an [[apparent magnitude]] of +10.42. The star is known to be a [[variable star]] with its [[star magnitude|magnitude]] varying by around 0.5.<ref>{{cite web|url=http://www.sai.msu.su/gcvs/cgi-bin/ident.cgi?cat=IRAS+&num=22317%2B5838|title=IRAS 22317+5838|accessdate=July 06, 2020|publisher=sai.msu.su|work=General Catalogue of Variable Stars}}</ref><ref>
