233 Asterope is a main-belt asteroid that was discovered by A. Borrelly on May 11, 1883, in Marseilles, 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.

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.[1]
