531040 (2012 CS57) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2012 CS57 as potentially hazardous because its orbit does not bring it close to Earth.
2012 CS57 orbits the sun every 104,000 days (284.74 years), coming as close as 41.86 AU and reaching as far as 44.50 AU from the sun. Based on its brightness and the way it reflects light, 2012 CS57 is probably between 140.138 to 313.357 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.
2012 CS57's orbit is 40.90 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.
2012 CS57's orbit is determined by observations dating back to March 10, 2005. It was last officially observed on March 2, 2022. The IAU Minor Planet Center records 73 observations used to determine its orbit.
