Overview

141354 (2002 AJ29) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2002 AJ29 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.

2002 AJ29 orbits the sun every 1,030 days (2.82 years), coming as close as 1.09 AU and reaching as far as 2.89 AU from the sun. Based on its brightness and the way it reflects light, 2002 AJ29 is probably between 0.888 to 1.986 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

The rotation of 2002 AJ29 has been observed. It completes a rotation on its axis every 10.80 hours.

Close Approaches

2002 AJ29's orbit is 0.09 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.

2002 AJ29 has 3 close approaches predicted in the coming decades:
