NGC 70
Galaxy in the constellation Andromeda
From Wikipedia, the free encyclopedia
NGC 70 is a spiral galaxy located in the constellation Andromeda.[7] It was discovered on October 7, 1855, by R. J. Mitchell[7] and was observed on December 19, 1897, by Guillaume Bigourdan from France who described it as "extremely faint, very small, round, between 2 faint stars".[2]

NGC 70 hosts a Seyfert Type II Active galactic nucleus (AGN).
NGC 70 is a member of a compact 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 the NGC 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 famous Stephan's Quintet group, and it is a popular target for amateur astrophotographers.
