Notes. (a) Some classify object 52872 as a Centaur, but because its Tisserand parameter $T_{\rm J}$ is less than 3.05 ($T_{\rm J}$ = 2.95) it is ``rapidly perturbed by Jupiter'' according to Gladman et al. (2008).
(b) From Stansberry et al. (2008).
(c) a, e, and i are the orbital elements semi-major axis, eccentricity and inclination, respectively.
(d) Classifications are performed using the taxonomic system designed by Barucci et al. (2005a). The designation comes from Fulchignoni et al. (2008) for Okyrhoe and Orcus and from Perna et al. (2010) for (73480) 2002 PN34.
