Overview

153220 (2000 YN29) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 YN29 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2000 YN29 orbits the sun every 1,480 days (4.05 years), coming as close as 0.83 AU and reaching as far as 4.25 AU from the sun. Based on its brightness and the way it reflects light, 2000 YN29 is probably between 0.876 to 1.959 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2000 YN29's orbit is 0.04 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.

2000 YN29 has 8 close approaches predicted in the coming decades:
