NGC 3110, also known asNGC 3122 andNGC 3518, is an activespiral galaxy in the constellationSextans.[1][2] It contains extensive Hubble-type Sbstar-forming regions, and is located south of thecelestial equator.[3] It is estimated to be 218 million light-years from theMilky Way and has a diameter of around 100,000 ly. Together with PGC 29184 it forms a gravitationally bound galaxy pair. Located in the same area of the sky is the galaxyIC 589.[4]
Multipleastronomers have documented NGC 3110 as different objects in theNGC catalogue. The object was first discovered byWilliam Herschel on March 5, 1785,[5][6] but this observation appears in the NGC catalogue under the designation NGC 3122. This galaxy was also observed by the French astronomerÉdouard Stephan on February 17, 1884, and it is this observation which was entered in the NGC catalogue under the designation NGC 3110. Finally, the American astronomerOrmond Stone also observed this galaxy on December 31, 1885, and this observation was entered in the NGC catalogue under the designation NGC 3518.[6]
NGC 3110 has a broad HI line and is a bright infrared galaxy (LIRG).[7] It also contains regions of ionized hydrogen.[7] To date, three non-redshift measurements give a distance of 54.300 ± 1.375 Mpc (~177 million ly), which is outside theHubble distance values.[7]
