Overview

318411 (2005 AH14) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 AH14 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.

2005 AH14 orbits the sun every 1,290 days (3.53 years), coming as close as 0.91 AU and reaching as far as 3.73 AU from the sun. Based on its brightness and the way it reflects light, 2005 AH14 is probably between 1.006 to 2.249 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

The rotation of 2005 AH14 has been observed. It completes a rotation on its axis every 9.65 hours.

Close Approaches

2005 AH14's orbit is 0.08 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.

2005 AH14 has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
May 12, 2026 14,065,789 13.113
June 10, 2033 20,785,121 12.927
June 30, 2040 24,477,684 13.226
May 20, 2121 15,633,973 12.845
June 29, 2128 24,227,505 12.932
