523789 (2015 FN345) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2015 FN345 as potentially hazardous because its orbit does not bring it close to Earth.
2015 FN345 orbits the sun every 98,400 days (269.40 years), coming as close as 37.87 AU and reaching as far as 45.57 AU from the sun. Based on its brightness and the way it reflects light, 2015 FN345 is probably between 152.952 to 342.011 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.
2015 FN345's orbit is 36.90 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 FN345's orbit is determined by observations dating back to April 27, 2012. It was last officially observed on May 16, 2023. The IAU Minor Planet Center records 159 observations used to determine its orbit.
