Object name: NGC5591
Designation(s): NGC5591, NGC5587,
NGC 5591 is a double galaxy in Bootes about 540 million light-years away. The galaxies appear to be making their first encounter. Whether their velocities are such they will merge I've not found. Come back in a 100 million years and we should have a good answer to this. The western component is listed at NED as Sdm pec with a starburst nucleus. In this case, the starburst activity appears related to their interaction. The eastern component is classed as simply Sc. The NGC project takes the approach that this is one strongly disrupted galaxy classed as Sc pec. To me, it is quite obvious these are two galaxies rather than one disrupted one. I doubt they looked anything like what we see today before the encounter began. It was found by Lewis Swift on June 4, 1886.
