Overview

7482 (1994 PC1) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1994 PC1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1994 PC1 orbits the sun every 572 days (1.57 years), coming as close as 0.90 AU and reaching as far as 1.79 AU from the sun. 1994 PC1 is about 1.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 1994 PC1 has been observed. It completes a rotation on its axis every 2.60 hours.

1994 PC1's spectral type None (Tholen) / S (SMASSII) indicates that it is likely to contain and .
