17161 (1999 LQ13) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1999 LQ13 as potentially hazardous because its orbit does not bring it close to Earth.
1999 LQ13 orbits the sun every 2,240 days (6.13 years), coming as close as 2.81 AU and reaching as far as 3.89 AU from the sun. 1999 LQ13 is about 16.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.
The rotation of 1999 LQ13 has been observed. It completes a rotation on its axis every 7.72 hours.
1999 LQ13's orbit is 1.80 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.
1999 LQ13's orbit is determined by observations dating back to Nov. 4, 1988. It was last officially observed on June 10, 2023. The IAU Minor Planet Center records 2,497 observations used to determine its orbit.
