'''NGC 5875''' is a [[spiral galaxy]] in the [[constellation]] of [[Boötes]]. Its velocity with respect to the [[cosmic microwave background]] is 3585 ± 6 km/s, which corresponds to a [[Hubble's law|Hubble distance]] of 52.87 ± 3.70 [[Megaparsec|Mpc]] (~173 million [[light-years]]).<ref name="ned" /> It was discovered by German-British astronomer [[William Herschel]] on 1 May 1788.<ref name="selig">{{cite web | url = https://cseligman.com/text/atlas/ngc58a.htm#5875 | title = New General Catalogue Objects: NGC{{nbsp}}5875 | last = Seligman | first = Courtney | website = Celestial Atlas | access-date = 14 December 2024}}</ref>

The [[SIMBAD]] database lists NGC 5875 as a [[Seyfert galaxy|Seyfert]] II Galaxy, i.e. it has a quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.<ref name="SIMBAD">{{cite simbad | title=NGC 5875| access-date=16 December 2024}}</ref>
