NGC 5829 forms a galaxy pair Arp 42 with the irregular galaxy IC 4526.[5] Although interacting, the two are not close since IC 4526 is located at a much further distance at 665 million light-years compared to NGC 5829.[6]
Hickson 73
NGC 5829 is a member of Hickson Compact Group 73 alongside IC 4526. There are three other galaxies in the group: HCG 73C (PGC 53720), HCG 73D (PGC 53703) and HCG 73E (PGC 53702). But they are not an actual galaxy group since they lie at different redshifts.[7]
Supernova
One supernova has been discovered so far in NGC 5829: SN 2008B. It was found by a Japanese astronomer, Koichi Itagaki via unfiltered images taken in January 2008 in Yamagata, Japan.[8] The supernova was located 23" east and 7" north of the nucleus,[9] and confirmed to be classified as Type IIn.[10]
