Overview

527715 (2007 YQ56) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 YQ56 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 YQ56 orbits the sun every 445 days (1.22 years), coming as close as 0.81 AU and reaching as far as 1.47 AU from the sun. Based on its brightness and the way it reflects light, 2007 YQ56 is probably between 0.269 to 0.603 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

The rotation of 2007 YQ56 has been observed. It completes a rotation on its axis every 60.80 hours.

Close Approaches

2007 YQ56's orbit is 0.01 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.

2007 YQ56 has 18 close approaches predicted in the coming decades:
