NGC 7079 is a barred lenticular galaxy located about 110.58 million light-years away in the constellation of Grus. NGC 7079 is also classified as a LINER galaxy. It is tilted about 51° to the Earth's line of sight. NGC 7079 was discovered by astronomer John Herschel on September 6, 1834.
Physical characteristics
NGC 7079 has a faint cigar-shaped bar with ansae at the ends, and there is another very faint spiral structure surrounding it. The rim of the disk also has a somewhat faint ring-like structure.
Emission of doubly ionized oxygen gas
In NGC 7079, it has been indicated that there is a faint emission of doubly ionized oxygen. The ionized 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.
Group membership
NGC 7079 is a member of the NGC 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 the Pavo–Indus and Virgo Superclusters. The other members of the NGC 7079 Group are NGC 7070, NGC 7070A, NGC 7097, NGC 7097A, ESO 287-37, ESO 287-39, ESO 287-41, and ESO 287-43.
