IC 701 is a merging bar-spiral galaxy of the Hubble-type SBdm in the constellation Leo at the ecliptic . It is estimated to be 272 million light years from the Milky Way and about 50,000 light years in diameter.
Together with VV 3b , it forms the pair of galaxies Arp 197 . Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class of galaxies with matter ejected from the nucleus .
In the same area of the sky are u. a. the galaxies NGC 3697 and IC 700 .
The supernovae SN 2004gj (Type-IIb) and SN 2013gl (Type-Ib) were observed here.
The object was discovered by Lewis Swift on April 22, 1889 .
