'''IC 755''', also known as '''NGC 4019''',<ref name=SIMBAD/> is a [[barred spiral galaxy]].<ref name=NED/> It lies about 60 million light-years away (18 [[Megaparsec]]s)<ref name=Smartt/> in the northern [[constellation]] of [[Coma Berenices]]. It is a member of the [[Virgo Cluster]].<ref name=Suk/>

In 1999 a star within IC 755 was seen to explode as a supernova and named SN 1999an.<ref name=Smartt/> Supernovae like SN 1999an are classified as [[Type II supernova|Type II]]<ref name=Smartt/> and they are dramatic events that mark the end of the lives of massive stars. The supernova was discovered by the Beijing Astronomical Observatory Supernova Survey.
