NGC 4125 is an elliptical galaxy in the constellation Draco. It was discovered on 4 January 1850 by English astronomer John Russell Hind.[3]
On 28 May 2016, the telescope KAIT discovered the supernova SN 2016coj (type Ia, mag. 14.8)[4] in this galaxy.[5] After detection, it became brighter over the course of several days.[5] It reached magnitude 13, making it the brightest supernova of 2016.[6]
