NGC 1527 is a lenticular galaxy in the constellation of Horologium. Its velocity with respect to the cosmic microwave background is 1,178±17 km/s, which corresponds to a Hubble distance of 56.7 ± 4.1 Mly (17.37 ± 1.27 Mpc). Additionally, 10 non-redshift measurements give a mean distance of 55.87 ± 3.62 Mly (17.130 ± 1.111 Mpc). It was discovered by Scottish astronomer James Dunlop on 28 September 1826.

NGC 1527 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.

Galaxy group

NGC 1527 is a member of a galaxy group known as HDC 257. The group contains at least 14 galaxies, including NGC 1433, NGC 1483, NGC 1487, NGC 1493, NGC 1494 [fr], NGC 1495 [fr], NGC 1510, NGC 1512, IC 1959 [fr], IC 2000 (galaxy) [fr], ESO 201-14 [d], and two others.
