Overview
143651 (2003 QO104) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2003 QO104 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2003 QO104 orbits the sun every 1,140 days (3.12 years), coming as close as 1.01 AU and reaching as far as 3.26 AU from the sun. Based on its brightness and the way it reflects light, 2003 QO104 is probably between 1.609 to 3.598 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.
The rotation of 2003 QO104 has been observed. It completes a rotation on its axis every 114.40 hours.
Close Approaches
2003 QO104's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
2003 QO104 has 6 close approaches predicted in the coming decades:
