Object name: NGC3166
Designation(s): NGC3166, NGC3165, NGC3169,
NGC 3166 and 3169 are a pair of interacting galaxies Arp somehow missed. Third NGC galaxy is NGC 3165. All three are at the same redshift distance with any differences being within measurement error and relative velocity as they encounter each other. All three appear distorted with NGC 2169 on the east side being really tore up with tidal clouds and plumes everywhere. Some images indicate a curving plume from 3166 going southeast then back northeast to 3169. It is broken, not continuous in my image. Likely due to my very short exposure time. A much broader connection seems to go directly east/west between the two so it is hard to tell where one ends and the other begins. With all the debris from their interaction, I don't understand way Arp didn't include this one in his atlas of peculiar galaxies. They are located in Sextans about 73 to 78 million light-years away. If this is correct these are two very large galaxies. NGC 3166 would be about 120 thousand light-years across. NGC 3169 would be 145 thousand light-years across. "Little" NGC 3165 would be 33 thousand light-years in diameter.
