Overview

2007 RU17 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 RU17 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 RU17 orbits the sun every 1,060 days (2.90 years), coming as close as 0.35 AU and reaching as far as 3.72 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2007 RU17 is probably between 0.595 to 1.331 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

2007 RU17'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.

2007 RU17 has 6 close approaches predicted in the coming decades:
