Editing Messier 5 (section)

==Discovery and visibility==
M5 is, under extremely good conditions, just visible to the naked eye as a faint "star" 0.37 of a degree (22' ([[arcmin]])) north-west of [[star]] [[5 Serpentis]]. [[Binoculars]] and/or small [[telescope]]s resolve the object as non-stellar; larger telescopes will show some individual stars, some of which are as bright as [[apparent magnitude]] 10.6.<ref name="CouttsClement"/>
M5 was discovered by German astronomer [[Gottfried Kirch]] in 1702 when he was observing a [[comet]]. [[Charles Messier]] noted it in 1764 and—a studier of comets—cast it as one of his nebulae. [[William Herschel]] was the first to resolve individual stars in the cluster in 1791, counting roughly 200.<ref name="Herschel"/> Messier 5 is receding from the Solar System at a speed over 50 km/s.<ref>{{cite journal|doi=10.1086/118116|title=A Catalog of Parameters for Globular Clusters in the Milky Way|journal=The Astronomical Journal|volume=112|pages=1487|year=1996|last1=Harris|first1=William E.|bibcode=1996AJ....112.1487H}}</ref>
