NGC 4013
Template:Short description Template:Infobox Galaxy
NGC 4013 is an edge-on barred spiral galaxy about 55 million light-years away in the constellation Ursa Major. The disk of NGC 4013 shows a distinct "peanut"-shaped bulge in long exposure photographs that N-body computer simulations suggest is consistent with a stellar bar seen perpendicular to the line of sight.[1]
A recent deep color image of NGC 4013 revealed a looping tidal stream of stars extending over 80 thousand light-years from the Galactic Center. This structure is thought to be the remnants of a smaller galaxy that was torn apart by tidal forces as it collided with NGC 4013.[2]
Supernova SN 1989Z was discovered on December 30, 1989 at apparent magnitude 12.[3]
NGC 4013 is a member of the Ursa Major Cluster.[4] It is a member of the NGC 4111 Group,[5] which is part of the Ursa Major Cloud and is the second largest group in the cloud after the NGC 3992 Group.[6][7][8]
