NGC 315

NGC 315 is an elliptical galaxy in the constellation Pisces. Its velocity with respect to the cosmic microwave background is 4635 ± 22 km/s, which corresponds to a Hubble distance of 223.0 ± 15.7 Mly (68.36 ± 4.80 Mpc).^[1] In addition, eight non-redshift measurements give a distance of 208.58 ± 22.28 Mly (63.950 ± 6.830 Mpc).^[3] It was discovered by German-British astronomer William Herschel on September 11, 1784.^[4]

The SIMBAD database lists NGC 315 as a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.^[5]

According to A.M. Garcia, NGC 315 is the namesake of the NGC 315 Group (also known as LGG 14). This group contains 42 galaxies, including NGC 226, NGC 243, NGC 262, NGC 266, NGC 311, NGC 338, IC 43, IC 66, AND IC 69, among others.^[6] NGC 315, along with triple star NGC 313, and star NGC 316 are listed together as Holm 28 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.^[7]
