Overview

480820 (1998 VF32) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 1998 VF32 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1998 VF32 orbits the sun every 287 days (0.79 years), coming as close as 0.47 AU and reaching as far as 1.23 AU from the sun. Based on its brightness and the way it reflects light, 1998 VF32 is probably between 0.160 to 0.358 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
