Overview

162474 (2000 LB16) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 LB16 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 LB16 orbits the sun every 505 days (1.38 years), coming as close as 0.80 AU and reaching as far as 1.68 AU from the sun. Based on its brightness and the way it reflects light, 2000 LB16 is probably between 0.502 to 1.122 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2000 LB16'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.

2000 LB16 has 16 close approaches predicted in the coming decades:
