Kiryu is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Kiryu as potentially hazardous because its orbit does not bring it close to Earth.
Kiryu orbits the sun every 1,810 days (4.96 years), coming as close as 2.87 AU and reaching as far as 2.94 AU from the sun. Kiryu is about 7.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
Kiryu's orbit is 1.86 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.
Kiryu's orbit is determined by observations dating back to April 30, 1976. It was last officially observed on Jan. 19, 2023. The IAU Minor Planet Center records 3,064 observations used to determine its orbit.
