52872 Okyrhoe (/əˈkɪr./; from Greek: Ωκυρόη, Ωκυρρόη) is a centaur orbiting in the outer Solar System between Jupiter and Saturn. It was discovered on September 19, 1998, by Spacewatch.

Orbit

Centaurs have short dynamical lives due to strong interactions with the giant planets. Okyrhoe (1998 SG35) is estimated to have an orbital half-life of about 670 kiloannum.

Of objects listed as a centaur by the Minor Planet Center (MPC), JPL, and the Deep Ecliptic Survey (DES), Okyrhoe has the second smallest perihelion distance of a numbered centaur. Numbered centaur (315898) 2008 QD4 has a smaller perihelion distance.

Sublimation

Okyrhoe passed perihelion in early 2008, and exhibited important magnitude variations during March and April 2008. This could be a sign of sublimation of volatiles.

Name

It was named after Ocyrhoe, Greek mythology.
