NGC 6355 is a globular cluster located in the constellation Ophiuchus. It is at a distance of 28,000 light years away from Earth, and is currently part of the Galactic bulge.
NGC was discovered by the German-born British astronomer William Herschel on 24 May 1784. It was initially thought to be an open cluster, but its true nature as a globular cluster was later confirmed. It is a core-collapse cluster.
