523780 (2015 AN281) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2015 AN281 as potentially hazardous because its orbit does not bring it close to Earth.
2015 AN281 orbits the sun every 98,400 days (269.40 years), coming as close as 35.82 AU and reaching as far as 47.60 AU from the sun. Based on its brightness and the way it reflects light, 2015 AN281 is probably between 245.785 to 549.591 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to South Korea.
2015 AN281's orbit is 34.80 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.
2015 AN281's orbit is determined by observations dating back to Dec. 21, 2004. It was last officially observed on May 14, 2023. The IAU Minor Planet Center records 176 observations used to determine its orbit.
