13143 (1995 AF) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1995 AF as potentially hazardous because its orbit does not bring it close to Earth.
1995 AF orbits the sun every 1,590 days (4.35 years), coming as close as 2.23 AU and reaching as far as 3.11 AU from the sun. Based on its brightness and the way it reflects light, 1995 AF is probably between 7.388 to 16.521 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
The rotation of 1995 AF has been observed. It completes a rotation on its axis every 4.98 hours.
1995 AF's orbit is 1.22 AU from Earth's orbit at its closest point. This means that there is an extremely 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.
1995 AF's orbit is determined by observations dating back to Sept. 9, 1967. It was last officially observed on July 5, 2023. The IAU Minor Planet Center records 2,927 observations used to determine its orbit.
