438908 (2009 XO) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2009 XO as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2009 XO orbits the sun every 926 days (2.54 years), coming as close as 0.85 AU and reaching as far as 2.87 AU from the sun. Based on its brightness and the way it reflects light, 2009 XO is probably between 0.211 to 0.472 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
2009 XO'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.
2009 XO has 12 close approaches predicted in the coming decades:
