'''NGC 7752 and NGC 7753''' are a pair of galaxies approximately 272 million [[light-year]]s away in the [[constellation]] [[Pegasus (constellation)|Pegasus]]. They were discovered by [[R. J. Mitchell (astronomer)|R. J. Mitchell]] on 22 November 1854.<ref name="selig">{{cite web | url=https://cseligman.com/text/atlas/ngc77a.htm#7752 | title = New General Catalogue Objects: NGC{{nbsp}}7752 (with NGC 7753 = Arp 86) | last = Seligman | first = Courtney | website = Celestial Atlas | access-date = 20 May 2025}}</ref>

NGC 7753 is the primary galaxy. It is a [[barred spiral galaxy]] with a small nucleus. NGC 7752 is the [[satellite galaxy]] of NGC 7753. It is a [[barred lenticular galaxy]] that is apparently attached to one of NGC 7753's [[spiral arm]]s. They resemble the [[Whirlpool Galaxy]] (M51A) and its satellite [[NGC 5195]] (M51B).
