Overview

2010 LZ63 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 LZ63 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 LZ63 orbits the sun every 949 days (2.60 years), coming as close as 0.45 AU and reaching as far as 3.33 AU from the sun. Its orbit is highly elliptical. 2010 LZ63 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

2010 LZ63'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.

2010 LZ63 has 11 close approaches predicted in the coming decades:
