NGC 3607 is an unbarred spiral galaxy that forms part of the Leo II Group (NGC 3607 Group) of galaxies.
Orbital motions of the globular cluster system
imply an unusual poverty of dark matter:
perhaps 16±44% of the total mass within 5 effective radii.
Recent article shows that its central black hole has a mass of about
M• = (1.2 ± 0.4) × 108 M⊙
