'''NGC{{nbsp}}5888''' is a [[barred spiral galaxy]] in the [[constellation]] of [[Boötes]]. Its velocity with respect to the [[cosmic microwave background]] is {{val|8817|8|u=km/s|fmt=commas}}, which corresponds to a [[Hubble's law|Hubble distance]] of {{convert|130.04 ± 9.10|Mpc|Mly|abbr=on|lk=on|order=flip}}.{{r|ned}} It was discovered by German-British astronomer [[William Herschel]] on 9 April 1787.<ref>{{cite journal |last=Herschel |first=W. |date=1789 |title=Catalogue of a Second Thousand of New Nebulae and Clusters of Stars; with a Few Introductory Remarks on the Construction of the Heavens |journal=[[Philosophical Transactions of the Royal Society of London]] |volume=79 |pages=212–255 |bibcode=1789RSPT...79..212H |doi=10.1098/rstl.1789.0021 |doi-access=free}}</ref><ref name="selig">{{cite web | url = https://cseligman.com/text/atlas/ngc58a.htm#5888 | title = New General Catalogue Objects: NGC{{nbsp}}5888 | last = Seligman | first = Courtney | website = Celestial Atlas | access-date = 5 August 2025}}</ref>

NGC 5888 is a [[Low-ionization nuclear emission-line region|LINER]] galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.<ref name="SIMBAD">{{cite simbad | title=NGC 5888 | access-date=5 August 2025}}</ref> It also has an [[active galactic nucleus|active galaxy nucleus]], i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.{{r|SIMBAD}}

NGC 5888, together with [[NGC 5886]], form a gravitationally bound [[galaxy group|pair of galaxies]].<ref>{{cite journal |last1=Tempel |first1=Elmo |last2=Kruuse |first2=Maarja |last3=Kipper |first3=Rain |last4=Tuvikene |first4=Taavi |last5=Sorce |first5=Jenny G. |last6=Stoica |first6=Radu S. |title=Bayesian group finder based on marked point processes.
