NGC 70 is aspiral galaxy located in the constellationAndromeda.[7] It was discovered on October 7, 1855, byR. J. Mitchell[7] and was observed on December 19, 1897, byGuillaume Bigourdan fromFrance who described it as "extremely faint, very small, round, between 2 faint stars".[2]
NGC 70 hosts aSeyfert Type IIActive galactic nucleus (AGN).
NGC 70 is a member of acompact group of seven[8] or eight[9] galaxies, sometimes called the NGC 70 Group or the VV 166 Group.
The group comprises three relatively bright galaxies: 70, 71 and 72 in theNGC catalog, and four fainter galaxies. NGC 68 appears to be a group member, but its discrepant radial velocity and lack of tidal distortion suggest that it may be an unrelated galaxy along the group's line of sight.[9] In photographs, the NGC 70 group resembles the much more famousStephan's Quintet group, and it is a popular target for amateur astrophotographers.
