Object name: IC0997
Designation(s): IC0997, IC0998, IC4401,
IC 997 is a pair of interacting galaxies in eastern Virgo about 330 million light-years distant. It is composed of PGC 51220 a Sc? pec spiral according to Seligman and PGC 1057935, an S? pec spiral again by Seligman. The pair was discovered by Lewis Swift on May 16, 1892. NED says identification is not certain while Seligman says it is certain. Flip a coin. It appears to me that PGC 51220 is in front of PGC 1057935 though both have the about the same redshift. Both have plumes. I measure PGC 51220 at about 120,000 light-years across and PGC 1057935 at 85,000 light-years.
