Overview

2003 GP51 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2003 GP51 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2003 GP51 orbits the sun every 1,150 days (3.15 years), coming as close as 0.86 AU and reaching as far as 3.45 AU from the sun. Based on its brightness and the way it reflects light, 2003 GP51 is probably between 0.106 to 0.237 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2003 GP51's orbit is 0.04 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.

2003 GP51 has 1 close approaches predicted in the coming decades:
