Encyclopedic overview

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

The morphological class of NGC 6753 is (R)SA(r)b, 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. The galaxy is flocculent in appearance with a prominent central region. The virial mass of the galaxy is ~1×10 M☉, while the stellar mass is 3.2×10 M☉. It has a star formation rate of 15.5 M☉·yr, which is confined to a radius of 15 kpc around the core. The most active region of star formation is the inner ring. It has a hot, X-ray luminous corona that extends out to a radius of 50 kpc.
