It was discovered by [[Charles Messier]] in [[1764]]. M9 is one of the nearer globular clusters to the center of the [[Milky Way Galaxy]] with a distance of around 5,500 [[light-year]]s. Its distance from [[Earth]] is 25,800 light-years. The total [[luminosity]] of this cluster is around 120,000 times that of the [[Sun]], the [[absolute magnitude]] being -8.04. The brightest individual [[star]]s in M9 are of [[apparent magnitude]] 13.5, making them visible in moderately sized [[telescope]]s. There have been 13 [[variable star]]s found in M9. Nearby, at about 80' to the northeast of M9 is the dimmer globular cluster [[NGC 6356]], while at about 80' to the southeast is the globular [[NGC 6342]]. ==External links== * [http://www.seds.org/messier/m/m009.html Messier 9, SEDS Messier pages] * [http://venus.mporzio.astro.it/~marco/gc/cluster_4.php?ggc=M+9 M9, Galactic Globular Clusters Database page] * {{WikiSky}} ==References== <div class="references-small"><references/></div> [[Category:Globular clusters|Messier 009]] [[Category:Ophiuchus constellation|Messier 009]] [[Category:Messier objects|009]] [[Category:NGC objects|Messier 009]] {{star-cluster-stub}} [[bg:M9]] [[ca:Messier 9]] [[cs:Messier 9]] [[co:M9]] [[de:Messier 9]] [[es:Cúmulo globular M9]] [[eo:M9]] [[fr:M9]] [[ko:M9 (천체)]] [[hr:Messier 9]] [[it:M9 (astronomia)]] [[lt:Mesjė 9]] [[hu:Messier 9]] [[nl:Messier 9]] [[ja:M9 (天体)]] [[pl:Messier 9]] [[ru:Шаровое скопление М9]] [[sk:Hviezdokopa M9]] [[fi:Messier 9]] [[sv:M9]] [[uk:Кулясте скупчення M9]] [[zh:M9 (球狀星團)]]
