'''NGC 5772''' is a large [[spiral galaxy]] in the [[constellation]] of [[Boötes]]. Its velocity with respect to the [[cosmic microwave background]] is {{val|5001|9|u=km/s|fmt=commas}}, which corresponds to a [[Hubble's law|Hubble distance]] of {{convert|73.77 ± 5.17|Mpc|Mly|abbr=on|lk=on|order=flip}}.{{r|ned}} Additionally, five ''non-redshift'' measurements give a slightly closer mean distance of {{convert|71.240 ± 10.409|Mpc|Mly|abbr=on|lk=off|order=flip}}.{{r|ned-distance}} It was discovered by British astronomer [[John Herschel]] on 12 May 1828.{{r|selig}}

NGC 5772 is a [[Seyfert galaxy|Seyfert]] galaxy, i.e. it has a [[quasar]]-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.{{r|seyfert|SIMBAD}} It is also a [[radio galaxy]], i.e. it has giant regions of radio emission extending well beyond its visible structure.{{r|radio|SIMBAD}}

==Supernovae== Two [[supernova]]e have been observed in NGC 5772: * '''SN 2002ee''' ([[Type II supernova#Light curves for Type II-L and Type II-P supernovae|Type{{nbsp}}II-P]], mag. 18.4) was discovered by [[Puckett Observatory#Tim Puckett|Tim Puckett]] and D. Toth on 19 July 2002.{{r|IAUC7941|TNS-2002ee}} * '''SN 2015bb''' ([[Type Ib and Ic supernovae|Type{{nbsp}}Ic]], mag. 17.0) was discovered by Kunihiro Shima on 16 November 2015.{{r|CBET4211|TNS-2015bb}}
