However, five non-redshift measurements give a farther mean distance of. It was discovered by German-British astronomer William Herschel on 29 June 1799.
NGC 6389 is an active galaxy nucleus candidate, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
