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 (fr), NGC 6855 (fr), NGC 6867 (fr), IC 4935 (de), IC 4950 (de), IC 4952 (de), IC 4963 (de), and ESO 185-54 (de).[5][6]

Supernova

One supernova has been observed in NGC 6862:

  • SN 2010co (Type II-P, mag. 16.1) was discovered by Berto Monard (it) on 6 May 2010.[7][8]
