120178 (2003 OP32) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2003 OP32 as potentially hazardous because its orbit does not bring it close to Earth.
2003 OP32 orbits the sun every 105,000 days (287.47 years), coming as close as 38.91 AU and reaching as far as 47.97 AU from the sun. Based on its brightness and the way it reflects light, 2003 OP32 is probably between 417.402 to 933.340 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to Great Britain.
The rotation of 2003 OP32 has been observed. It completes a rotation on its axis every 9.71 hours.
2003 OP32's orbit is 38.00 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.
2003 OP32's orbit is determined by observations dating back to July 21, 1990. It was last officially observed on June 28, 2023. The IAU Minor Planet Center records 577 observations used to determine its orbit.
