Datenbanklinks zu NGC 20
NGC 6 = NGC 20 ist eine elliptische Galaxie vom Hubble-Typ E/S0 im Sternbild Andromeda am Nordsternhimmel. Sie ist schΓ€tzungsweise 227 Millionen Lichtjahre von der MilchstraΓe entfernt und hat einen Durchmesser von etwa 115.000 Lichtjahren. Die Galaxie gilt als Mitglied der NGC 7831-Gruppe (LGG 1).
Das Objekt wurde am 18. September 1857 von dem irischen Astronomen R. J. Mitchell, einem Assistenten von William Parsons, entdeckt. Der Astronom Lewis A. Swift beobachtete diese Galaxie am 20. September 1885. Die Doppelbeobachtung wurde jedoch nicht erkannt, und so trug die Galaxie zwischenzeitlich zwei Katalognummern: NGC 20 (Parsons Beobachtung) und NGC 6 (Swift).cite-ref-5[5]
