2018 UQ1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 UQ1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2018 UQ1 orbits the sun every 749 days (2.05 years), coming as close as 0.82 AU and reaching as far as 2.41 AU from the sun. Based on its brightness and the way it reflects light, 2018 UQ1 is probably between 0.107 to 0.239 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
The rotation of 2018 UQ1 has been observed. It completes a rotation on its axis every 3.93 hours.
2018 UQ1's orbit is 0.01 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.
2018 UQ1 has 15 close approaches predicted in the coming decades:
