M 10

About image

M10 is a globular cluster in the constellation of Ophiucus.
It is located in an area of sky far from bright stars, but thanks to its magnitude of 6.6 is easily visible with binoculars.
The cluster is one of the closest to us since it is only 14,000 light years away. Despite a modest diameter of only 60 light years, its apparent diameter is rather large and is equivalent to half the diameter of the full moon.
