IC 1166 are a pair of galaxies in the Corona Borealis constellation[1] comprising IC 1166 NED01[2] and IC 1166 NED02.[3] They are located 977 million light-years from the Solar System[4] and were discovered on July 28, 1892, by Stephane Javelle.[5]
Galaxies
IC 1166 NED01
IC 1166 NED01[6] or PGC 56771[7] is a type E[7] elliptical galaxy.[8] Located above IC 1166 NED02, it has a diameter of approximately 110,000 light-years.[5] PGC 56771 has an active nucleus and it is classified as a Seyfert type 1 galaxy.[6] It has a quasar-like appearance, but its host clearly seen and presents two sets of emission lines which are superimposed on each other.[9] PGC 56771 is classified a Markarian galaxy (designated Mrk 867), because compared to other galaxies its nucleus emits excessive amounts of ultraviolet rays.[10] It has a surface brightness of 23.2 magnitude and, located at right ascension (16:02:08.92) and declination (26:19:45.60) respectively.[8]
IC 1166 NED02
IC 1166 NED02[11] or PGC 1771884[12] is a type SBbc[12] spiral galaxy.[13] Located below IC 1166 NED01, it has an approximate diameter of 160,000 light-years making it slightly larger compared to the other galaxy[5] and does not have an active galactic nucleus.[11] PGC 1771884 has a surface brightness of 23.4 magnitude and, a right ascension of (16:02:08.83) and declination (26:19:31.20).[13]
