NGC 2315 is a lenticular galaxy in the constellation of Lynx. Its velocity with respect to the cosmic microwave background is 6,369±60 km/s, which corresponds to a Hubble distance of 306.4 ± 21.8 Mly (93.94 ± 6.69 Mpc).[1] It was discovered by British astronomer John Herschel on 16 February 1831.[2]

NGC 2315 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.[3] It also has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[4][5]

LDC 484 Group

NGC 2315 is a member of a group of galaxies known as LDC 484. This group contains 47 galaxies, including NGC 2320, NGC 2321, NGC 2322, NGC 2326, NGC 2329, NGC 2332, NGC 2340, IC 458, and IC 465.[6][7]
