Messier 10 or NGC 6254 is a globular cluster in constellation Ophiuchus. It is too dim to be seen with the unaided eye (visual magnitude 6.5) It has an apparent diameter of some 20', about 2/3 that of the moon. Viewed through medium sized telescopes it appears about half that size, as its brighter core is only 35 light-years across. It is 14,400 light-years away. It is 83 light-years across.
