M30 lies immensely far from the Solar System at a distance of approximately 27,100 light years, and thus the intensely luminouscluster is dimmed by distance to a faint visual magnitude of just +7.19. The cluster is old enough to undergone core collapse, a process that leads to a highly dense inner core. M30 occupies a region of space more than ninety light years across, though, unlike typical globular clusters, this region is not spherical, but shows a distinctly elongated shape.
