Overview

2014 YW34 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 YW34 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2014 YW34 orbits the sun every 610 days (1.67 years), coming as close as 0.81 AU and reaching as far as 2.01 AU from the sun. Based on its brightness and the way it reflects light, 2014 YW34 is probably between 0.127 to 0.284 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2014 YW34's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2014 YW34 has 18 close approaches predicted in the coming decades:
