163364 (2002 OD20) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 OD20 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2002 OD20 orbits the sun every 583 days (1.60 years), coming as close as 0.86 AU and reaching as far as 1.87 AU from the sun. Based on its brightness and the way it reflects light, 2002 OD20 is probably between 0.302 to 1.352 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.
The rotation of 2002 OD20 has been observed. It completes a rotation on its axis every 2.42 hours.
2002 OD20's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2002 OD20 has 17 close approaches predicted in the coming decades:

2002 OD20's orbit is determined by observations dating back to Nov. 22, 2001. It was last officially observed on Feb. 1, 2021. The IAU Minor Planet Center records 520 observations used to determine its orbit.
2002 OD20 can be reached with a journey of 362 days. This trajectory would require a delta-v of 10.755 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 384 potential trajectories and launch windows to this asteroid.
