17685 (1997 AJ19) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1997 AJ19 as potentially hazardous because its orbit does not bring it close to Earth.
1997 AJ19 orbits the sun every 1,710 days (4.68 years), coming as close as 2.67 AU and reaching as far as 2.93 AU from the sun. Based on its brightness and the way it reflects light, 1997 AJ19 is probably between 3.652 to 8.167 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
The rotation of 1997 AJ19 has been observed. It completes a rotation on its axis every 5.30 hours.
1997 AJ19's orbit is 1.68 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.
1997 AJ19's orbit is determined by observations dating back to Nov. 30, 1986. It was last officially observed on June 25, 2023. The IAU Minor Planet Center records 1,978 observations used to determine its orbit.
