38181 (1999 JG124) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 1999 JG124 as potentially hazardous because its orbit does not bring it close to Earth.
1999 JG124 orbits the sun every 1,280 days (3.50 years), coming as close as 1.64 AU and reaching as far as 2.98 AU from the sun. Based on its brightness and the way it reflects light, 1999 JG124 is probably between 3.094 to 6.919 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.
The rotation of 1999 JG124 has been observed. It completes a rotation on its axis every 9.52 hours.
1999 JG124's orbit is 0.75 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 JG124's orbit is determined by observations dating back to Aug. 21, 1982. It was last officially observed on March 12, 2023. The IAU Minor Planet Center records 3,134 observations used to determine its orbit.
