It was discovered by [[Charles Messier]] in [[1764]], and resolved into stars by [[William Herschel]] around 1784. This cluster is one of the largest and brightest, and is made up of around 500,000 stars. It is located at a distance of about 33,900 [[light-year]]s away from [[Earth]]. M3 has an [[apparent magnitude]] of 6.2, making it visible to the [[naked eye]] under dark conditions. From a moderate-sized telescope, the cluster is fully defined. ==External links== *[http://www.seds.org/messier/m/m003.html SEDS Messier pages on M3] *[http://venus.mporzio.astro.it/~marco/gc/cluster_4.php?ggc=M+3 M3, Galactic Globular Clusters Database page] *{{WikiSky}} ==References== <div class="references-small"><references/></div> [[Category:Globular clusters|Messier 003]] [[Category:Canes Venatici constellation|Messier 003]] [[Category:Messier objects|003]] [[Category:NGC objects|Messier 003]] {{star-cluster-stub}} [[bg:M3]] [[ca:Messier 3]] [[cs:Messier 3]] [[co:M3]] [[de:Messier 3]] [[es:Cúmulo globular M3]] [[eo:M3]] [[fr:M3 (amas globulaire)]] [[ko:M3 (천체)]] [[hr:Messier 3]] [[it:M3 (astronomia)]] [[lb:Messier 3]] [[lt:Mesjė 3]] [[hu:Messier 3]] [[nl:Messier 3]] [[ja:M3 (天体)]] [[pl:Messier 3]] [[ro:Messier 3]] [[ru:Шаровое скопление М3]] [[sk:Hviezdokopa M3]] [[fi:Messier 3]] [[sv:M3 (stjärnhop)]] [[uk:Кулясте скупчення M3]] [[zh:M3 (球狀星團)]]
