NGC 4323

NGC 4323 is a lenticular or dwarf elliptical galaxy[7] located about 52.5 million light-years away in the constellation Coma Berenices. The galaxy was discovered in 1882 by astronomer Wilhelm Tempel[8] and is a member of the Virgo Cluster.[9]

NGC 4323 is commonly misidentified as NGC 4322, which is a 13th magnitude star.[10][11]

Interaction with Messier 100

NGC 4323 is a companion of Messier 100,[12][13][14][15][16][17][18][19][20][21][22] which lies 78,000 light-years (24 kiloparsecs) away.[13][17][21] The two galaxies appear to be interacting,[15][19][20][22] as evidenced by Messier 100's rotation curve, an asymmetry of its HI disk,[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]
