NGC 4216 is a metal-rich[2] intermediate spiral galaxy located not far from the center of the Virgo Cluster[2] of galaxies, roughly 55 million light-years away.[2] It is seen nearly edge-on.

Physical characteristics


NGC 4216 is one of the largest and brightest spiral galaxies of the Virgo Cluster, with an absolute magnitude that has been estimated to be −22 (i.e.: brighter than the Andromeda Galaxy),[3] and like most spiral galaxies of this cluster shows a deficiency of neutral hydrogen that is concentrated within the galaxy's optical disk and has a low surface density for a galaxy of its type.[4] This explains why NGC 4216 is considered an anemic galaxy by some authors, also with a low star formation activity for a galaxy of its type.[5] In fact, the galaxy's disk shows pillar-like structures that may have been caused by interactions with the intracluster medium of Virgo and/or with nearby galaxies.[6]

In NGC 4216's halo, besides a rich system of globular clusters estimated to number around 700 (nearly five times more than the Milky Way),[3] two stellar streams that are interpreted as two satellite galaxies being disrupted and absorbed by this galaxy are present.[6]

NGC 4216 seems to be in a place of the Virgo cluster where dwarf galaxies are being destroyed/accreted at a high rate, with it suffering many interactions with these type of galaxies.[7]

[de] NGC 4216

NGC 4216 ist eine Balken-Spiralgalaxie vom Hubble-Typ SBb im Sternbild Jungfrau am Nordsternhimmel. Sie ist schätzungsweise 53 Millionen Lichtjahre von der Milchstraße entfernt und hat einen Durchmesser von etwa 130.000 Lichtjahren. Bei dem Objekt handelt es sich um eine sogenannte Edge-On-Galaxie, d. h. wir sehen sie nahezu in Kantenstellung. Die Spiralarme erscheinen hier als dunkle staubhaltige Wolken, beleuchtet vom hellen Kern der Galaxie. Die Galaxie ist unter der Katalognummer VCC 167 als Teil des Virgo-Clusters gelistet.

[es] NGC 4216

NGC 4216 es una galaxia espiral que se encuentra a unos cuarenta millones de años luz de distancia en la constelación de Virgo. Se localiza casi en el borde con Coma Berenices, 6º y 40 arcmin al este-sureste de Denébola (β Leonis). No está lejos del centro del cúmulo de Virgo, del que forma parte. De magnitud aparente 11,0 y brillo superficial 13,1 mag/arcsec2, puede ser observada con pequeños telescopio. Se ve casi de canto, mostrando cierto parecido con la galaxia de Andrómeda.
