233 Asterope is a largemain-beltasteroid that was discovered on 11 May 1883, by French astronomerAlphonse Borrelly atMarseille Observatory in Marseille, France. The asteroid was named afterAsterope (or Sterope), one of thePleiades.
This asteroid is orbiting theSun with asemimajor axis of2.66 AU, aperiod of 4.34 years, and aneccentricity of 0.10. Theorbital plane is inclined by 7.68° to theplane of the ecliptic. It is a rareT-type asteroid[3] and has a relatively dark surface. The spectrum of 233 Asterope bears a resemblance toTroilite, a sulfurous iron mineral found in most iron meteorites.[4]
Photometric observations during 1995 show a rotation period of19.743 hours.[3] Measurements made with theIRAS observatory give a diameter of 109.56 ± 5.04 km and ageometric albedo of 0.08 ± 0.01. By comparison, the MIPSphotometer on theSpitzer Space Telescope gives a diameter of 97.54 ± 10.32 km and a geometric albedo of 0.10 ± 0.01.[5]
