NGC 4513 is a lenticular galaxy[2][3][4] and a ring galaxy[4][5][3] located about 110 million light-years away[2][3] in the constellation Draco. It was discovered by astronomer Heinrich d'Arrest on October 16, 1866.[6]

Physical characteristics
editNGC 4513 has a large and very faint ring[7] that is quite separated from the main galactic disk.[8] The disk is gaseous and counter-rotates with respect to the inner disc. The outer part of the inner disc exhibits a population of counter-rotating stars that may be related to the outer ring.[8][3] The observed counter-rotation suggests that the ring resulted from the accretion of gas from the passage of another galaxy.[3] However, Ilyina et al. proposed that the ring is the result of a satellite galaxy vertically impacting onto the central part of NGC 4513 as the ring is bright in UV and is symmetric.[9]
Group Membership
editNGC 4513 is a member of the NGC 4256 Group[10] which lies in the upper plane of the Virgo Supercluster.[11]
