Ul is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Ul 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.
Ul orbits the sun every 1,110 days (3.04 years), coming as close as 1.27 AU and reaching as far as 2.93 AU from the sun. Based on its brightness and the way it reflects light, Ul is probably between 1.395 to 3.119 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.
Ul's orbit is 0.28 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.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
Ul's orbit is determined by observations dating back to Sept. 14, 1982. It was last officially observed on Jan. 29, 2020. The IAU Minor Planet Center records 188 observations used to determine its orbit.
