Overview

523732 (2014 PG51) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 PG51 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2014 PG51 orbits the sun every 484 days (1.33 years), coming as close as 0.66 AU and reaching as far as 1.75 AU from the sun. Based on its brightness and the way it reflects light, 2014 PG51 is probably between 0.196 to 0.439 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2014 PG51'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.

2014 PG51 has 16 close approaches predicted in the coming decades:
