NGC 5927 is a globular cluster in the constellation Lupus. NGC 5927 has a diameter of about 12 arcminutes and an apparent magnitude of +8.86. Its Shapley–Sawyer Concentration Class is VIII,[2] and it contains stars of magnitude 15 and dimmer.
The globular cluster was discovered by the astronomer James Dunlop in 1826 and was also observed in 1834 by John Herschel.[4]
NGC 5927 is relatively metal-rich for a globular cluster, and may have multiple generations of stars.[5]
