Located in the direction of Scorpius in a rich field of stars, it is an estimated 37,000 ly from Earth, but just 3,300 ly from the galactic centre. Consequently, light from NGC 6453 (the small yellow cluster upper right of centre) has experienced much interaction with clouds of dust and gas on its journey to us. Its mass is about 1.7x105 solar masses.
Classified as IV (intermediate rich concentrations) on the Shapley-Sawyer globular cluster concentration scale (1927).
On the left of the image is part of the bright open cluster, M7 (Ptolemy's Cluster).
