NGC 5963 is a spiral galaxy in the northern constellation of Draco.[1] It was discovered on May 5, 1788 by German-British astronomer William Herschel.[10] NGC 5963 has an apparent visual magnitude of 13.1[1] and is located at a distance of 42 million light-years (13.0 Mpc) from the Milky Way galaxy.[5][6] It has an angular separation of just 9′ from NGC 5965, but the two galaxies are not physically related.[1] Although it is relatively isolated,[11] NGC 5963 is sometimes classified as a member of the NGC 5866 Group of galaxies.[6]

The morphological classification of NGC 5963 is Sc, indicating a spiral galaxy with somewhat loosely wound spiral arms.[5] It is characterized by an unusually low surface brightness and has just a hint of a bulge component.[11][1] There is a high surface brightness nuclear region with an oval shape spanning ~40″, which forms a spiral sub-system. Surrounding this is a patchy, loosely wound spiral forming a faint disk.[11] The rotation curve of NGC 5963 matches that of similar galaxies with normal surface brightness, suggesting this galaxy has a more concentrated halo.[5]
