Overview

487577 (2014 YQ15) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2014 YQ15 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2014 YQ15 orbits the sun every 346 days (0.95 years), coming as close as 0.74 AU and reaching as far as 1.19 AU from the sun. Based on its brightness and the way it reflects light, 2014 YQ15 is probably between 0.106 to 0.473 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2014 YQ15'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.

2014 YQ15 has 18 close approaches predicted in the coming decades:
