17371 (1981 DT) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1981 DT as potentially hazardous because its orbit does not bring it close to Earth.
1981 DT orbits the sun every 1,990 days (5.45 years), coming as close as 2.93 AU and reaching as far as 3.27 AU from the sun. 1981 DT is about 10.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.
The rotation of 1981 DT has been observed. It completes a rotation on its axis every 6.14 hours.
1981 DT's orbit is 1.94 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.
1981 DT's orbit is determined by observations dating back to Feb. 9, 1981. It was last officially observed on Feb. 17, 2023. The IAU Minor Planet Center records 2,650 observations used to determine its orbit.
