NGC 5965 is a

spiral galaxy Spiral galaxies form a galaxy morphological classification, class of galaxy originally described by Edwin Hubble in his 1936 work ''The Realm of the Nebulae''

located in the constellation Draco. It is located at a distance of circa 150 million

e have been observed in NGC 5965: SN 2001cm ( type II, mag. 17.5) and SN 2018cyg (type II, mag. 17). NGC 5965 is seen nearly edge-on, with an inclination of 80 degrees. Dust is seen across the galactic disk, while there is also a red dust lane at the nucleus. The bulge is X-shaped, that suggests that the galaxy is actually barred. NGC 5965 along with another edge-on galaxy, NGC 5746, were the galaxies used to confirm that peanut shaped bulges are associated with the presence of a bar, by spectrographically observing the disturbance caused at the velocity distributions of the galaxies. The galaxy features some level of disk disturbance, like a warp, as the outer part of the disk along with a ring-like dust lane appear to be on a different plane from the bulge, but it could also be a projection effect. When observed in the K band, the galaxy features a stellar ring. NGC 5965 lies in a galaxy filament which also includes NGC 5987 and its loose group, which includes NGC 5981, NGC 5982, NGC 5985, three galaxies known as the Sampler.
