NGC 4323is alenticularordwarf ellipticalgalaxy[7]located about 52.5 millionlight-yearsaway in theconstellationComa Berenices.The galaxy was discovered in 1882 by astronomerWilhelm Tempel[8]and is a member of theVirgo Cluster.[9]

NGC 4323 is commonly misidentified asNGC 4322,which is a 13th magnitudestar.[10][11]

Interaction with Messier 100

[edit]

NGC 4323 is a companion ofMessier 100,[12][13][14][15][16][17][18][19][20][21][22]which lies 78,000 light-years (24kiloparsecs) away.[13][17][21]The two galaxies appear to beinteracting,[15][19][20][22]as evidenced by Messier 100's rotation curve, an asymmetry of itsHIdisk,[19][20]and a faint, optical bridge that connects it to NGC 4323.[14][15][16][17][20][22]However, Knapen et al. suggests that the two galaxies are not interacting as NGC 4323 is a small galaxy and has a large separation from Messier 100.[19]
