}}Thisbe ({{IPAc-en|ˈ|θ|ɪ|z|b|iː}} {{Respell|THIZ|bee}}; minor planet designation: 88 Thisbe) is the 13th largest main-belt asteroids. It was discovered by C. H. F. Peters on June 15, 1866, and named after Thisbe, heroine of a Roman fable. An occultation of a star by Thisbe was observed on October 7, 1981. Results from the occultation indicate a larger than expected diameter of 232 km.[13][2]During 2000, 88 Thisbe was observed by radar from the Arecibo Observatory. The return signal matched an effective diameter of 207 ± 22 km. This is consistent with the asteroid dimensions computed through other means.[15]
Photometric observations of this asteroid during 1977 gave a light curve with a period of 6.0422 ± 0.006 hours and a brightness variation of 0.19 in magnitude.[8]Perturbation
Thisbe has been perturbed by asteroid 7 Iris and in 2001 Michalak estimated it to have a mass of 1.5{{e|19}} kg.[3][4] But Iris is strongly perturbed by many minor planets such as 10 Hygiea and 15 Eunomia.[3]
In 2008, Baer estimated Thisbe to have a mass of 1.05{{e|19}} kg.[5] In 2011 Baer revised this to 1.83{{e|19}} kg with an uncertainty of 1.09{{e|18}} kg.[5]
