NGC 3607 is a small but fairly bright[7] lenticular galaxy[3] in the equatorial constellation of Leo, about 2.5° south of the prominent star Delta Leonis.[8] The galaxy was discovered March 14, 1784 by William Herschel. Dreyer described it as "very bright, large, round, very much brighter middle, 2nd of 3".[9] It is located at a distance of 73 million light years and is receding with a radial velocity of 930 km/s.[2] The galaxy lies southwest of NGC 3626 at an angular separation of ~50′.[7] It occupies the center of the Leo II Group of galaxies, forming one of its two brightest members – the other being NGC 3608.[3] It is a member of the NGC 3607 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster.[10]
The morphological class of NGC 3607 is SA(s)0*,[5] matching a lenticular galaxy (SA0) with no inner ring structure (s). It is an intermediate mass galaxy[3] that is being viewed at an inclination of 34°,[5] showing an ellipticity of 0.13 with the major axis oriented along a position angle of 125°.[3] The galaxy has an outer dusty disk with a second perpendicular disk that is falling inward toward the center of the galaxy.[3] X-ray emission from hot gas has been detected in the interior and from all around the galaxy.[5]
A system of 46 confirmed globular clusters have been identified around NGC 3607, which are orbiting within an effective radius of 14.2±2.0 kpc. In contrast, the stellar component of the galaxy has an effective radius of 4.2±1 kpc.[3] Orbital motions of this cluster system[11] imply an unusual poverty of dark matter: perhaps 16%±44% of the total mass within 5 effective radii. Its central black hole has a mass of M• = (1.2±0.4)×108M☉[12] The core region of the galaxy is kinematically distinct from the remainder of the galaxy and shows an enhancement of magnesium.[5]
