NGC 1512 is a bar-spiral galaxy with an active nucleus of the Hubble type S0 in the constellation Pendulum Clock in the southern sky . It is an estimated 33 million light years from the Milky Way and about 110,000 light years in diameter .
The elliptical galaxy NGC 1510 is only about four arc minutes southwest of NGC 1512 from Earth . In fact, there is also an interaction between the two galaxies: the latter is a companion galaxy and is responsible for some slight deformations of its outer spiral structure. The two galaxies are also listed together under the designation HIPASS J0403-43 in the HIPASS catalog. A detailed image of the center was taken in a study using the Hubble Space Telescope.
Together with NGC 1510 and NGC 1487 , it forms the small NGC 1512 group .
