NGC 4145
NGC 4145 is a barred spiral galaxy located 68 million light years from the Earth. The galaxy has little star formation, except on its outer edges. Due to the loss of energy that occurs without star formation, some astronomers predict that the galaxy will degenerate into a lenticular galaxy in the near future. However, the galaxy's interaction with NGC 4151 may "maintain star formation".
NGC 4145 is a member of the NGC 4151 Group.
