Messier 19 or M19 (also designated NGC 6273) is a w:globular cluster in the w:constellation w:Ophiuchus. It was discovered by w:Charles Messier in w:1764 and added to his catalogue of w:comet-like objects that same year.
M19 is the most w:oblate of the known globular clusters. It is at a distance of about 28,000 w:light-years from the w:Solar System, and is quite near to the w:Galactic Center, at only about 5,200 light-years away.
