88 Thisbe is the 13th largest main-belt asteroid. C. H. F. Peters discovered it on 15 June 1866, named after Thisbe, heroine of a Roman fable. This asteroid orbits the Sun at a distance of 414.025 Gm over a period of 1681.709 days and an orbital eccentricity (ovalness) of 0.165. The orbital plane is inclined at an angle of 5.219° to the ecliptic.
On 7 October 1981, asteroid 88 Thisbe was observed to occult the 9th-magnitude star SAO 187124 from 12 sites. The timing of the different chords across the asteroid provided a diameter estimate of . This is 10% larger than the diameter estimate based on radiometric techniques. 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.
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.
Perturbation
Asteroid 7 Iris has perturbed Thisbe; in 2001, Michalak estimated it to have a mass of 15 kg.{{cite journal |last=Michalak |first=G. |title=Determination of asteroid masses |journal=Astronomy & Astrophysics |volume=374 |pages=703–711 |year=2001 |doi=10.1051/0004-6361:20010731 |url=https://www.aanda.org/articles/aa/full/2001/29/aa10228/aa10228.html |access-date=2008-11-06 |bibcode=2001A&A...374..703M |issue=2 |doi-access=free
In 2008, Baer estimated Thisbe to have a mass of 10.5 kg. |year=2011 |title=Recent Asteroid Mass Determinations |publisher=Personal Website |author=Jim Baer |url=http://home.earthlink.net/~jimbaer1/astmass.txt |access-date=2012-04-12 |archive-url=https://web.archive.org/web/20130702212735/http://home.earthlink.net/~jimbaer1/astmass.txt |archive-date=2013-07-02 |url-status=dead In 2011, Baer revised this to 18.3 kg with an uncertainty of 1.1 kg.
