466 Tisiphone is an asteroid which orbits among the Cybele family of asteroids.

Discovery

It was discovered by Max Wolf and Luigi Carnera on January 17, 1901, and was assigned the provisional designation 1901 FX.

Physical properties

A number of positional observations of Tisiphone were carried out in 1907, [Languageicon|de|German Cite journal | title = Genäherte Oppositions-Ephemeriden von 38 kleinen Planeten für 1907 Januar bis 1907 August | last = Bauschinger | first = J. | coauthors = Berberich, A.; Neugebauer, P.

In 1992 a simple check of 466 Tisiphone's position was made by The Association of Lunar and Planetary Observers (ALPO). The asteroid was found to be in the expected position to within observational errors.Cite journal | title = General Report of Position Observations by the ALPO Minor Planets Section for the Year 1992 | last = Pilcher | first = F. | date = September 1993 | journal = The Minor Planet Bulletin | volume = 20 | pages = 23–28 | url = http://adsabs.harvard.edu/abs/1993MPBu...20...23P] Further checks were carried out in 1996,Cite journal | title = General Report of Position Observations by the ALPO Minor Planets Section for the Year 1996 | last = Pilcher | first = F. | date = September 1997 | journal = The Minor Planet Bulletin | volume = 24 | pages = 18–30 | url = http://adsabs.harvard.edu/abs/1997MPBu...24...18P] and 2006Cite journal | title = General Report of Position Observations by the ALPO Minor Planets Section for the Year 2006 | last = Pilcher | first = F. | date = September 2007 | journal = The Minor Planet Bulletin | volume = 34 | issue = 3 | pages = 85–91 | url = http://adsabs.harvard.edu/abs/2007MPBu...34...85P ( [http://www.minorplanetobserver.com/mpb/MPB%2034-3.pdf pdf] )] with the asteroid in its expected position both times.

In 1997 Tisiphone was studied by Worman and Christianson at the Feder Observatory located near Minnesota State University, Moorhead, with the goal of determining its rotational peroid. A peroid of 8.824 ± 0.009 was arrived at, with the lightcurve data showing two distinct maxima and minima in its rotation.

In 2001 Lagerkvist "et al." published their results on a study of the Cybele asteroid family, which includes 466 Tisiphone. Relative photometric observations of Tisiphone were carried out in 1998 and 1999 using the 1.2 m telescope at the Calar Alto Observatory located at the Max-Planck-Institut für Astronomie in Heidelberg, Germany. They were able to confirm the 8.8 hour rotation period obtained by Worman and Christianson.

In 2006 Fornasier "et al." published polarimetric data for a number of asteroids, including 466 Tisiphone.Cite journal | title = Polarimetric survey of asteroids with the Asiago telescope | last = Fornasier | first = S. | coauthors = "et al." | date = August 2006 | journal = Astronomy and Astrophysics | volume = 455 | issue = 1 | pages = 371–377 | url = http://adsabs.harvard.edu/abs/2006astro.ph..4614F | doi = 10.1051/0004-6361:20064836]
