M 69 NGC 6637 is a dense globular star cluster located in the southern constellation Sagittarius. It is one of the most metal-rich globular clusters ever observed. In astronomy, the term "metal" refers to any element heavier than the two most common elements in our universe, hydrogen and helium. Ancient globular clusters have much lower metallic abundances than more recently formed stars, such as the sun. The stars in M69 have over ten times more iron than stars in other globular clusters of the same age. This cluster is about 28,700 light-years away from Earth and 5,200 light-years from the Galactic Centre, with a spatial radius of 45 light-years and is 200,000 solar mass. In 10×50 binoculars, M69 appears as a fuzzy star, while small telescopes will show a comet-like shape. Apparent magnitude 8.31
