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]
One supernova has been observed in NGC 4216: SN 2024gy (type Ia, mag. 16.3).[8]
