18703 (1998 HN68) is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1998 HN68 as potentially hazardous because its orbit does not bring it close to Earth.
1998 HN68 orbits the sun every 2,110 days (5.78 years), coming as close as 2.84 AU and reaching as far as 3.59 AU from the sun. 1998 HN68 is about 9.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
1998 HN68's orbit is 1.82 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.
1998 HN68's orbit is determined by observations dating back to Jan. 11, 1997. It was last officially observed on Nov. 16, 2022. The IAU Minor Planet Center records 1,730 observations used to determine its orbit.
