UGC 8153 also referred to as Z 43-114, is a spiral galaxy of morphological type of Sd and is located in the constellation of Virgo.[1] The galaxy is approximately 153 million light years (47 megaparsecs) away from Earth and has an apparent B magnitude of 15.2.[2] The first known reference to this galaxy comes from Volume I of the Catalogue of Galaxies and of Clusters of Galaxies compiled by Fritz Zwicky in 1961, where it was listed as CGCG 043-114, and described as "diffuse".[3]
UGC 8153 is a small spiral galaxy in the Virgo Cluster.[2] It is 72,200 light years (22,150 parsecs) across based on a distance of 153 million light years (46.98 megaparsecs) and an angular diameter of 108 arcsecs.[1] It is believed to be a very low mass galaxy with an estimated stellar mass of 10^9.8 or roughly 6 billion M☉.[4]
In the galactic center of UGC 8153 potentially has an active galactic nucleus (AGN).[2] It is centered on a lighter intermediate-mass black hole which is predicted to have a mass of 10^4.1 or ~12,500 M☉, making it one of the least massive central black holes discovered.[4]
