Object name: ARP176
Designation(s): ARP176, NGC4933, IC4173, IC4176,
Arp 176 is a pair of interacting galaxies also known as NGC 4933 though this designation includes a third non-interacting galaxy. The IC catalog lists the two interacting galaxies separately as IC 4173 and IC 4176 west to east (right to left). They are located about 160 million light-years away in the constellation of Virgo. Arp put these in his category: Galaxies (not classifiable as S or E): Narrow counter tails. His comment on the pair is simply: "Companion galaxy [IC 4173] very condensed." Most notes seem to consider the streamer as coming from IC 4173. I'm not that convinced. Tearing out a tidal arm from such a tight E0 galaxy isn't easy. Tearing one from the far less dense IC 4176 seems to me far more likely.
