NGC 7079 is abarred lenticular galaxy[2] located about 110.58 millionlight-years away[3] in theconstellation ofGrus.[4][5] NGC 7079 is also classified as aLINER galaxy.[3][5] It is tilted about 51° to the Earth's line of sight.[2] NGC 7079 was discovered by astronomerJohn Herschel on September 6, 1834.[4]
NGC 7079 has a faint cigar-shaped bar withansae at the ends, and there is another very faint spiral structure surrounding it.[6][7] The rim of the disk also has a somewhat faint ring-like structure.[7]
In NGC 7079, it has been indicated that there is a faint emission ofdoubly ionized oxygen. Theionized gas is rotating in the opposite direction of the stars in the galaxy. The counter-rotation has been attributed to the accretion of gas from outside of the galaxy.[2]
NGC 7079 is a member of theNGC 7079 Group. The group, along with other nearby groups are part of the Pavo-Indus and Grus clouds of galaxies which form a connection between thePavo–Indus andVirgo Superclusters. The other members of the NGC 7079 Group areNGC 7070,NGC 7070A,NGC 7097,NGC 7097A,ESO 287-37,ESO 287-39,ESO 287-41, andESO 287-43.[8]
