Overview

2005 QZ151 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 QZ151 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2005 QZ151 orbits the sun every 985 days (2.70 years), coming as close as 0.81 AU and reaching as far as 3.06 AU from the sun. Based on its brightness and the way it reflects light, 2005 QZ151 is probably between 0.232 to 0.518 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2005 QZ151's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2005 QZ151 has 10 close approaches predicted in the coming decades:
