NGC 322 is a lenticular galaxy located approximately 318 million light-years from the Solar System in the constellation Phoenix. It was discovered on September 5, 1834 by John Herschel. It was described by Dreyer as "very faint, very small, round, a little brighter middle, 3 stars to west." It apparently seems to be interacting with PGC 95427, another galaxy.
One supernova, SN 2018bwv (type Ia, mag. 16.2), was discovered in NGC 322 on 23 May, 2018.
From legacy survey images a faint ring or tidal feature can be seen around NGC 322.
An image processing of the DECam data that makes these faint features of the ring or tidal feature appear.
^ An object's distance from Earth can be determined using Hubble's law: v=Ho is Hubble's constant (70±5 (km/s)/Mpc). The relative uncertainty Δd/d divided by the distance is equal to the sum of the relative uncertainties of the velocity and v=Ho
