NGC 6862 is a barred spiral galaxy in the constellation of Telescopium. Its velocity with respect to the cosmic microwave background is 4,100±9 km/s, which corresponds to a Hubble distance of 197.3 ± 13.8 Mly (60.48 ± 4.24 Mpc).[1] It was discovered by British astronomer John Herschel on 9 July 1834.[2]
NGC 6862 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.[3][4]
ESO 185-54 Group
NGC 6862 is a member of the ESO 185-54 group (also known as LGG 429). This group contains nine galaxies, including NGC 6848, NGC 6855, NGC 6867, IC 4935, IC 4950, IC 4952, IC 4963, and ESO 185-54.[5][6]
