550310 (2012 DD86) is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2012 DD86 as potentially hazardous because its orbit does not bring it close to Earth.
2012 DD86 orbits the sun every 40,500 days (110.88 years), coming as close as 15.34 AU and reaching as far as 30.78 AU from the sun. Based on its brightness and the way it reflects light, 2012 DD86 is probably between 33.617 to 75.169 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.
2012 DD86's orbit is 14.30 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.
2012 DD86's orbit is determined by observations dating back to Nov. 12, 2005. It was last officially observed on June 22, 2023. The IAU Minor Planet Center records 358 observations used to determine its orbit.
