12389 (1994 WU) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1994 WU as potentially hazardous because its orbit does not bring it close to Earth.
1994 WU orbits the sun every 1,980 days (5.42 years), coming as close as 2.58 AU and reaching as far as 3.59 AU from the sun. 1994 WU is about 19.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Denver.
1994 WU's orbit is 1.61 AU from Earth's orbit at its closest point. This means that there is an extremely 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.
1994 WU's orbit is determined by observations dating back to Nov. 8, 1983. It was last officially observed on May 9, 2023. The IAU Minor Planet Center records 3,166 observations used to determine its orbit.
