NGC 5754 is a barred spiral galaxy located 218 million light years away in the constellation Boötes. It was discovered by German-British astronomer William Herschel on 16 May 1787.[5]
NGC 5754 is listed in the Atlas of Peculiar Galaxies as Arp 297, an interacting galaxies group, which consists of NGC 5752, NGC 5753, NGC 5754, NGC 5755. Along with NGC 2718 and UGC 12158, NGC 5754 is often considered a twin of the Milky Way.
One supernova has been observed in NGC 5754: SN 2021mnj (type II, mag. 18.8).[6]
