IC 755, also known as NGC 4019, [3] is a barred spiral galaxy. [6] It lies about 60 million light-years away (18 Megaparsecs) [4] in the northern constellation of Coma Berenices. It is a member of the 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 [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.
