**IC 755**, also known as **NGC 4019**,[3] is a [barred spiral galaxy](/source/Barred_spiral_galaxy).[6] It lies about 60 million light-years away (18 [Megaparsecs](/source/Megaparsec))[4] in the northern [constellation](/source/Constellation) of [Coma Berenices](/source/Coma_Berenices). It is a member of the [Virgo Cluster](/source/Virgo_Cluster).[5]

In 1999 a star within IC 755 was seen to explode as a supernova and named SN 1999an.[4] Supernovae like SN 1999an are classified as [Type II](/source/Type_II_supernova)[4] 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.
