163023 (2001 XU1) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2001 XU1 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2001 XU1 orbits the sun every 260 days (0.71 years), coming as close as 0.36 AU and reaching as far as 1.23 AU from the sun. Based on its brightness and the way it reflects light, 2001 XU1 is probably between 0.367 to 0.820 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, very roughly comparable in size to the U.S. Capitol building.
2001 XU1's orbit is 0.06 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.
2001 XU1 has 20 close approaches predicted in the coming decades:
