'''466 Tisiphone''' is an [[asteroid]] which orbits among the [[Cybele asteroid|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,<ref>{{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 [[Association of Lunar and Planetary Observers|The Association of Lunar and Planetary Observers]] (ALPO).

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.<ref name=ccd-photometry/>
In 2001 Lagerkvist ''et al.'' published their results on a study of the Cybele asteroid family, which includes 466 Tisiphone. Relative [[Photometry (astronomy)|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.<ref name=cybele-study/>
In 2006 Fornasier ''et al.'' published [[Polarimetry|polarimetric]] data for a number of asteroids, including 466 Tisiphone.<ref name=polarimetry>{{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}}</ref>
