39229 (2000 YJ30) is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2000 YJ30 as potentially hazardous because its orbit does not bring it close to Earth.
2000 YJ30 orbits the sun every 4,330 days (11.85 years), coming as close as 4.35 AU and reaching as far as 6.04 AU from the sun. Based on its brightness and the way it reflects light, 2000 YJ30 is probably between 7.457 to 16.674 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
2000 YJ30's orbit is 3.38 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.
2000 YJ30's orbit is determined by observations dating back to Oct. 14, 1998. It was last officially observed on March 13, 2023. The IAU Minor Planet Center records 704 observations used to determine its orbit.
