IC 167 is a barred spiral galaxy in the constellation of Aries. It was first reported by Bigourdan in 1891[1] and included in Dreyer's first Index Catalogue.[2]

Galaxy group information

IC 167 is a member of the NGC 697 group.[3] There is some evidence that IC 167 is interacting with nearby NGC 694 as they seem to share HI regions.[3] The tidal warping of IC 167 also is indicative of an interaction with another galaxy.[3] How long the interaction between these two galaxies has been occurring is the subject of current research.[4]
