Key Facts

Overview

68359 (2001 OZ13) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2001 OZ13 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.

2001 OZ13 orbits the sun every 683 days (1.87 years), coming as close as 1.25 AU and reaching as far as 1.78 AU from the sun. Based on its brightness and the way it reflects light, 2001 OZ13 is probably between 0.671 to 1.500 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

The rotation of 2001 OZ13 has been observed. It completes a rotation on its axis every 18.07 hours.

No Close Approaches

2001 OZ13's orbit is 0.28 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.

Images and Observations

2001 OZ13's orbit is determined by observations dating back to Feb. 4, 1995. It was last officially observed on July 2, 2021. The IAU Minor Planet Center records 1,106 observations used to determine its orbit.

Accessibility and Exploration

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