Overview

163243 (2002 FB3) is a mid-sized asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2002 FB3 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2002 FB3 orbits the sun every 243 days (0.67 years), coming as close as 0.30 AU and reaching as far as 1.22 AU from the sun. 2002 FB3 is about 1.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of 2002 FB3 has been observed. It completes a rotation on its axis every 6.23 days.
