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