'''Messier 3''' (also known as ''M3'' or ''NGC 5272'') is a [[globular cluster]] in the [[constellation]] [[Canes Venatici]]. 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.
