Key Facts

Overview

162926 (2001 OB36) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2001 OB36 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 OB36 orbits the sun every 1,840 days (5.04 years), coming as close as 1.12 AU and reaching as far as 4.76 AU from the sun. Based on its brightness and the way it reflects light, 2001 OB36 is probably between 1.001 to 2.239 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

No Close Approaches

2001 OB36's orbit is 0.42 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 OB36's orbit is determined by observations dating back to July 24, 2001. It was last officially observed on Feb. 5, 2007. The IAU Minor Planet Center records 59 observations used to determine its orbit.

Accessibility and Exploration

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