17171 (1999 NB38) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1999 NB38 as potentially hazardous because its orbit does not bring it close to Earth.
1999 NB38 orbits the sun every 4,260 days (11.66 years), coming as close as 4.71 AU and reaching as far as 5.57 AU from the sun. 1999 NB38 is about 40.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.
The rotation of 1999 NB38 has been observed. It completes a rotation on its axis every 64.79 hours.
1999 NB38's orbit is 3.69 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.
1999 NB38's orbit is determined by observations dating back to Aug. 11, 1953. It was last officially observed on July 1, 2023. The IAU Minor Planet Center records 2,294 observations used to determine its orbit.
