Nihonsyoki is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Nihonsyoki as potentially hazardous because its orbit does not bring it close to Earth.
Nihonsyoki orbits the sun every 2,020 days (5.53 years), coming as close as 2.73 AU and reaching as far as 3.53 AU from the sun. Nihonsyoki is about 13.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.
Nihonsyoki's orbit is 1.74 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.
Nihonsyoki's orbit is determined by observations dating back to April 21, 1955. It was last officially observed on June 26, 2023. The IAU Minor Planet Center records 2,816 observations used to determine its orbit.
