NGC 1741 is a distant pair ofinteracting galaxies (NGC 1741A andNGC 1741B) in theEridanus constellation.[3][4] It was discovered on 6 January 1878 by FrenchastronomerÉdouard Stephan.[5] As a result of the collision, the galaxies are in a rapidstarburst phase.[6][4] The galaxies are classed asWolf–Rayet galaxies due to their high content of rareWolf–Rayet stars.[7]
This pair of spiral galaxies is made up ofPGC 16570 (NGC 1741B) and PGC 16574 (NGC 1741A). This pair is part of theHalton Arp catalog as Arp 259 and theHickson Compact Group as HCG 31A (NGC 1741A) and HCG 31B (NGC 1741B).[6][5]
