Discovered in 1788 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "Two. The preceding [NGC 5857] cF, cS; the following [NGC 5859] pL; both lE np-sf, but nearer parallel."
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads SB,EL,MINC,2BWDARMS.
Steve Coe, using a 13" f/5.6, notes: "Faint, pretty small, round and little brighter in the middle at 165X. There is a very faint companion to the SW it is small and round."
