Key Facts

Overview

13189 (1997 AF13) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1997 AF13 as potentially hazardous because its orbit does not bring it close to Earth.

1997 AF13 orbits the sun every 1,270 days (3.48 years), coming as close as 1.89 AU and reaching as far as 2.70 AU from the sun. 1997 AF13 is about 4.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of 1997 AF13 has been observed. It completes a rotation on its axis every 5.94 hours.

No Close Approaches

1997 AF13's orbit is 0.88 AU from Earth's orbit at its closest point. This means that there is a very 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

1997 AF13's orbit is determined by observations dating back to Feb. 21, 1980. It was last officially observed on Nov. 19, 2022. The IAU Minor Planet Center records 1,921 observations used to determine its orbit.
