86373 (1999 YK) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 1999 YK as potentially hazardous because its orbit does not bring it close to Earth.
1999 YK orbits the sun every 969 days (2.65 years), coming as close as 1.56 AU and reaching as far as 2.27 AU from the sun. 1999 YK is about 1.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.
1999 YK's orbit is 0.73 AU from Earth's orbit at its closest point. This means that there is a very 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 YK's orbit is determined by observations dating back to Dec. 16, 1999. It was last officially observed on Aug. 20, 2022. The IAU Minor Planet Center records 1,430 observations used to determine its orbit.
