Pan is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Pan as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
Pan orbits the sun every 633 days (1.73 years), coming as close as 0.60 AU and reaching as far as 2.29 AU from the sun. Based on its brightness and the way it reflects light, Pan is probably between 1.011 to 2.260 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the U.S. Pentagon.
The rotation of Pan has been observed. It completes a rotation on its axis every 56.48 days.
Pan's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
Pan has 13 close approaches predicted in the coming decades:
