NGC 192 is a barred spiral galaxy of the Hubble-type (R ') SB (r) a: in the constellation Whale at the celestial equator, which is an estimated 189 million light-years away from the Milky Way . Together with NGC 196 , NGC 197 and NGC 201 , it forms the Hickson Compact Group HCG 7.
HCG stands for Hickson Compact Group . These are collections of bright galaxies that are comparatively isolated. It is believed that the galaxies of HCG 7 will approach and eventually merge . Simulations have shown that within a billion years these galaxies will form one giant galaxy.

The object was discovered on December 28, 1790 by the German-British astronomer Friedrich Wilhelm Herschel .
