Key Facts

Overview

Okyrhoe is a relatively small asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified Okyrhoe as potentially hazardous because its orbit does not bring it close to Earth.

Okyrhoe orbits the sun every 8,840 days (24.20 years), coming as close as 5.82 AU and reaching as far as 10.91 AU from the sun. Okyrhoe is about 36.0 kilometers in diameter, making it larger than most asteroids, comparable in size to the city of Los Angeles.

The rotation of Okyrhoe has been observed. It completes a rotation on its axis every 9.72 days.

No Close Approaches

Okyrhoe's orbit is 4.84 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

Okyrhoe's orbit is determined by observations dating back to Sept. 13, 1998. It was last officially observed on Aug. 18, 2018. The IAU Minor Planet Center records 537 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
