NGC 6753 is a massive[5] unbarred spiral galaxy,[5] seen almost exactly face-on, in the southern constellation of Pavo.[6] It was discovered by the English astronomer John Herschel on July 5, 1836.[9] The galaxy is located at a distance of 142 million light years from the Milky Way,[5] and is receding with a heliocentric radial velocity of 3,140 km/s.[4] It does not display any indications of a recent interaction with another galaxy or cluster.[5]

The morphological class of NGC 6753 is (R)SA(r)b,[8] indicating it is a spiral without an inner bar feature (SA), displaying outer (R) and inner (r) ring structures, and moderately wound spiral arms. It is being viewed nearly face-on with a galactic plane inclination by 30° to the line of sight from the Earth.[5] The galaxy is flocculent in appearance with a prominent central region.[8] The virial mass of the galaxy is ~1×1013 M☉, while the stellar mass is 3.2×1011 M☉. It has a star formation rate of 15.5 M☉·yr−1, which is confined to a radius of 15 kpc around the core.[5] The most active region of star formation is the inner ring.[10] It has a hot, X-ray luminous corona[6] that extends out to a radius of 50 kpc.[5]

Up to three supernovae have been discovered in this galaxy. The candidate type II-P supernova SN 2019mhm was discovered by the BOSS team on August 2, 2019. This transient was spotted close to maximum with a magnitude of 16.6, but showed no radio emission.[11][12] Supernova SN 2000cj was discovered by Robert Evans on May 14, 2000. It was positioned against a spiral arm at an offset 35″ east and 19″ south of the galaxy nucleus.[13] The spectrum showed this to be a type Ia supernova.[14] On May 13, 2005, type Ic supernovae SN 2005cb was spotted by the Brazilian Supernovae Search team.[15] It was offset 16″ west and 19″ north of the nucleus and reached a peak magnitude of 15.6.[16]
