'''NGC 2865'''是一個在天球上位於[[長蛇座]]的[[橢圓星系]]，距離地球超過1億光年。該星系於1835年由天文學家[[約翰·赫歇爾]]發現<ref name="Spacetelescope">{{Cite web|url=https://www.spacetelescope.org/images/potw1515a/|title=Young and dynamic|website=www.spacetelescope.org|language=en-GB|access-date=2018-11-03|archive-date=2018-11-03|archive-url=https://web.archive.org/web/20181103091851/https://www.spacetelescope.org/images/potw1515a/|dead-url=no}}</ref><ref>{{Cite news|url=http://www.sci-news.com/astronomy/science-hubble-galaxy-ngc2865-02689.html|title=Hubble Sees Shell Elliptical Galaxy NGC 2865 {{!}} Astronomy {{!}} Sci-News.com|work=Breaking Science News {{!}} Sci-News.com|access-date=2018-11-03|language=en-US|archive-date=2018-11-03|archive-url=https://web.archive.org/web/20181103091852/http://www.sci-news.com/astronomy/science-hubble-galaxy-ngc2865-02689.html|dead-url=no}}</ref><ref name="NGC 2865 - Simbad">{{cite web |title=NGC 2865 |url=http://simbad.u-strasbg.fr/simbad/sim-id?Ident=NGC++2865 |work=[[SIMBAD]] |publisher=u-strasbourg.fr |accessdate=5 November 2018 |archive-date=2018-11-05 |archive-url=https://web.archive.org/web/20181105202635/http://simbad.u-strasbg.fr/simbad/sim-id?Ident=NGC++2865 |dead-url=no }}</ref>。<br />

NGC 2865在橢圓星系中是相對較年輕的。該星系擁有一個快速旋轉的盤面，並且內部充滿恆星和富含金屬的氣體。因為NGC 2865的年輕恆星在橢圓星系中不尋常地多，天文學家推論在約10億年前該星系發生過[[星暴]]事件。並且該事件是NGC 2865的前身星系和另一個螺旋星系合併所引發<ref name="Spacetelescope" />。<br />
