This hunk of love was discovered by our main man Charles Messier in
1780, specifically August 31. Which, by the way, was the same
night he discovered M70. Interesting enough, he was trying to
verify the object that LaCaille had described back in 1751-2.
We’re not sure if LaCaille had actually described this globular
cluster or not.
M69 is some 29,700 light-years from earth with a spatial radius of some
42 light-years. Another claim-to-fame for this guy is the fact
that it is one of the most metal-rich globulars we have come
across. Also, there are only 1,800 light-years separating M69 and
its neighbor M70. (Not too surprisingly they were both discovered the
same night.) Both of these globular clusters lie close to our
Milky Way center.
