It was discovered by w:Charles Messier in August 31, w:1780, the same night he discovered M70. At the time, he was searching for an object described by LaCaille in 1751-2 and thought he had rediscovered it, but it is unclear if LaCaille actually described M69. M69 is at a distance of about 29,700 w:light-years away from w:Earth and has a spatial radius of 42 light-years. It is a close neighbor of w:Globular Cluster M70, 1,800 light-years separating the two objects, and both these clusters lie close to the Galactic Center. It is one of the most metal-rich globular cluster known. 0.2° view]] External links Globular Cluster M69 @ SEDS Messier pages Messier 69, Galactic Globular Clusters Database page References
