233 Asterope is a main-belt asteroid that was discovered by A. Borrelly on May 11, 1883, in Marseille, France. The asteroid was named after Asterope (or Sterope), one of the Pleiades. It is a rare T-type asteroid and has a relatively dark surface. The spectrum of 233 Asterope bears a resemblance to Troilite, a sulfurous iron mineral found in most iron meteorites.
Photometric observations during 1995 show a rotation period of 19.743 hours. Measurements made with the IRAS observatory give a diameter of 109.56 ± 5.04 km and a geometric albedo of 0.08 ± 0.01. By comparison, the MIPS photometer on the Spitzer Space Telescope gives a diameter of 97.54 ± 10.32 km and a geometric albedo of 0.10 ± 0.01.
