'''NGC 7052'''是一個位於[[狐狸座]]的橢圓星系。該星系由[[威廉·赫歇爾]]發現於1784年，距離地球約1.91億光年<ref name="Hubblesite">{{Cite web |url=http://hubblesite.org/newscenter/archive/releases/1998/22/image/a/ |title=Hubble Uncovers Dust Disk around a Massive Black Hole |accessdate=2015-03-17 |archive-date=2015-04-02 |archive-url=https://web.archive.org/web/20150402122536/http://hubblesite.org/newscenter/archive/releases/1998/22/image/a/ |dead-url=no }}</ref>。天文學家在該星系中心發現質量大約是 <math>3.70_{-1.50}^{+2.60}</math> 億倍[[太陽質量]]的[[超大質量黑洞]]<ref>{{cite journal|author=van der Marel, R.P.|author2=van den Bosch, F.C.|last-author-amp=yes|date=1998|title=Evidence for a 3 x 10<sup>8</sup> M<sub>⊙</sub> Black Hole in NGC 7052 from Hubble Space Telescope Observations of the Nuclear Gas Disk|journal=[[天文期刊|Astronomical Journal]]|volume=116|page=2220|bibcode=1998AJ....116.2220V|arxiv=astro-ph/9804194|doi=10.1086/300593}}</ref>。該黑洞外圍的氣體與塵埃盤質量大約是太陽的300萬倍。

NGC 7052還是個無限電波源，但中心噴流並不垂直銀河盤面。這可能是因為NGC 7052曾經和鄰近星系碰撞過<ref name="Hubblesite" />。
