It is a member of the NGC 5248 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.[2] Distance measurements to NGC 5248 vary from 41.4 million light-years (12.7 Mpc) to 74.0 million light-years (22.7 Mpc), averaging about 58.7 million light-years (17.7 Mpc).[1] References1. ^1 2 3 4 5 6 7 8 9 {{cite web | title=NASA/IPAC Extragalactic Database | work=Results for NGC 5248 | url=http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=NGC+5248&extend=no | accessdate=2010-11-27 }} 2. ^{{cite web | title=The Virgo III Groups | work=Atlas of the Universe | url=http://www.atlasoftheuniverse.com/galgrps/viriii.html | accessdate=2010-11-27 }} External links{{WikiSky}}{{Caldwell catalogue}}{{Ngc55}} 6 : Intermediate spiral galaxies|Boötes|NGC objects|UGC objects|Principal Galaxies Catalogue objects|Caldwell objects |
