Ondaatje is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Ondaatje as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
Ondaatje orbits the sun every 757 days (2.07 years), coming as close as 1.27 AU and reaching as far as 1.98 AU from the sun. Based on its brightness and the way it reflects light, Ondaatje is probably between 1.226 to 2.742 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.
The rotation of Ondaatje has been observed. It completes a rotation on its axis every 5.30 hours.
Ondaatje's orbit is 0.26 AU from Earth's orbit at its closest point. This means that there is a 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.
Ondaatje's orbit is determined by observations dating back to Dec. 29, 1983. It was last officially observed on Aug. 10, 2022. The IAU Minor Planet Center records 2,820 observations used to determine its orbit.
