511551 (2014 UD225) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2014 UD225 as potentially hazardous because its orbit does not bring it close to Earth.
2014 UD225 orbits the sun every 106,000 days (290.21 years), coming as close as 38.16 AU and reaching as far as 49.26 AU from the sun. Based on its brightness and the way it reflects light, 2014 UD225 is probably between 112.345 to 251.212 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Connecticut.
2014 UD225's orbit is 37.10 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.
2014 UD225's orbit is determined by observations dating back to Sept. 21, 2000. It was last officially observed on Oct. 20, 2020. The IAU Minor Planet Center records 70 observations used to determine its orbit.
