(52872) Okyrhoe is a planetoid that was discovered on September 19, 1998 as part of the Spacewatch program and belongs to the group of centaurs . The asteroid will orbit the sun on a moderately eccentric orbit in a good 24 years . The orbital eccentricity of its orbit is 0.306, which is 15.67 ° inclined to the ecliptic .
It is assumed that the Okyrhoe, like the two centaurs (2060) Chiron and (60558) Echeclus, also has cometary activities.
In mythology, Okyrhoe was the daughter of the centaur (2060) Chiron and the nymph (10199) Chariklo , which are the two largest confirmed centaurs in astronomy, both of which also have a fine ring system. The name means "quickly running" or "quickly flowing".
