'''NGC 5963''' is a [[spiral galaxy]] in the northern constellation of [[Draco (constellation)|Draco]].<ref name=König_Binnewies_2017/> It was discovered on May 5, 1788 by German-British astronomer [[William Herschel]].<ref name=cseligman/> NGC 5963 has an [[apparent visual magnitude]] of 13.1<ref name=König_Binnewies_2017/> and is located at a distance of {{convert|13.0|Mpc|e6ly|order=flip|lk=on}} from the [[Milky Way]] galaxy.<ref name="bosmaetal1988"/><ref name="sanchez2005"/> It has an [[angular separation]] of just {{val|9|u=arcminute}} from [[NGC 5965]], but the two galaxies are not physically related.<ref name=König_Binnewies_2017/> Although it is relatively isolated,<ref name=Romanishin_et_al_1982/> NGC 5963 is sometimes classified as a member of the [[NGC 5866 Group]] of galaxies.<ref name="sanchez2005" />

The [[Galaxy morphological classification|morphological classification]] of NGC 5963 is Sc, indicating a spiral galaxy with somewhat loosely wound [[spiral arm]]s.<ref name="bosmaetal1988"/> It is characterized by an unusually [[low surface brightness galaxy|low surface brightness]] and has just a hint of a [[galactic bulge|bulge]] component.<ref name=Romanishin_et_al_1982/><ref name=König_Binnewies_2017/> There is a high surface brightness nuclear region with an oval shape spanning {{val|40|u=arcsecond|p=~}}, which forms a spiral sub-system. Surrounding this is a patchy, loosely wound spiral forming a faint disk.<ref name=Romanishin_et_al_1982/> The [[rotation curve]] of NGC 5963 matches that of similar galaxies with normal surface brightness, suggesting this galaxy has a more concentrated [[galactic halo|halo]].<ref name="bosmaetal1988"/>
