Overview

2007 LU19 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 LU19 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 LU19 orbits the sun every 1,340 days (3.67 years), coming as close as 0.91 AU and reaching as far as 3.85 AU from the sun. Based on its brightness and the way it reflects light, 2007 LU19 is probably between 0.136 to 0.305 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2007 LU19's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2007 LU19 has 11 close approaches predicted in the coming decades:
