'''NGC 81''' ist eine [[linsenförmige Galaxie]] vom [[Hubble-Typ]] S0 im Sternbild Andromeda am [[Nordsternhimmel]]. Sie ist schätzungsweise 281 Millionen [[Lichtjahr]]e von der [[Milchstraße]] entfernt und hat einen Durchmesser von etwa 50.000 Lichtjahren. Vom [[Sonnensystem]] aus entfernt sich die Galaxie mit einer errechneten [[Radialgeschwindigkeit]] von näherungsweise 6100 Kilometern pro Sekunde.<br />
<br />
Das [[Astronomisches Objekt|Objekt]] wurde am 15. November 1873 von dem schottischen [[Astronom]]en [[Ralph Copeland]] entdeckt.<ref>[http://cseligman.com/text/atlas/ngc0a.htm#81 Seligman]</ref><br />
