Overview
2011 LA19 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2011 LA19 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2011 LA19 orbits the sun every 1,820 days (4.98 years), coming as close as 1.01 AU and reaching as far as 4.81 AU from the sun. 2011 LA19 is about 0.9 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.
Close Approaches
2011 LA19's orbit is 0.03 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.
2011 LA19 has 9 close approaches predicted in the coming decades:
