16506 (1990 UH1) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1990 UH1 as potentially hazardous because its orbit does not bring it close to Earth.
1990 UH1 orbits the sun every 1,330 days (3.64 years), coming as close as 1.79 AU and reaching as far as 2.94 AU from the sun. 1990 UH1 is about 8.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
1990 UH1's orbit is 0.81 AU from Earth's orbit at its closest point. This means that there is a very 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.
1990 UH1's orbit is determined by observations dating back to March 22, 1955. It was last officially observed on June 25, 2022. The IAU Minor Planet Center records 2,279 observations used to determine its orbit.
