Description:

M10 in the constellation of Ophiuchus has the honor of being one of the globular clusters in the Messier catalog that is nearest to Earth, lying only 14,600 light-years away. It is a Shapley-Sawyer class VII cluster, which means it has a densely populated but resolvable core that gives globular clusters the classic snowball of stars appearance.
