'''NGC 5248''' (also known as '''Caldwell 45''') is a compact [[intermediate spiral galaxy]] in the [[constellation]] [[Boötes]]. Its velocity with respect to the [[cosmic microwave background]] is 1437 ± 20{{nbsp}}km/s, which corresponds to a [[Hubble's law|Hubble distance]] of {{convert|21.19 ± 1.51|Mpc|Mly|abbr=on|lk=on|order=flip}}.<ref name="ned" /> However, 17 ''non redshift'' measurements give a much closer distance of {{convert|13.038 ± 0.969|Mpc|Mly|abbr=on|order=flip}}.<ref>{{cite web | url = https://ned.ipac.caltech.edu/cgi-bin/nDistance?name=NGC+5248 | title = Distance Results for NGC{{nbsp}}5248 | website = NASA/IPAC EXTRAGALACTIC DATABASE | publisher = [[NASA]] | access-date = 12 November 2024}}</ref> It was discovered on 15 April 1784 by [[Germany|German-British]] astronomer [[William Herschel]].<ref name="selig">{{cite web | url = https://cseligman.com/text/atlas/ngc52.htm#5248 | title = New General Catalogue Objects: NGC{{nbsp}}5248 | last = Seligman | first = Courtney | website = Celestial Atlas | access-date = 12 November 2024 }}</ref>
