Overview

483432 (2001 DF47) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2001 DF47 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2001 DF47 orbits the sun every 489 days (1.34 years), coming as close as 0.76 AU and reaching as far as 1.67 AU from the sun. Based on its brightness and the way it reflects light, 2001 DF47 is probably between 0.217 to 0.485 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2001 DF47's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2001 DF47 has 19 close approaches predicted in the coming decades:
