253515 (2003 SO159) is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2003 SO159 as potentially hazardous because its orbit does not bring it close to Earth.
2003 SO159 orbits the sun every 2,190 days (6.00 years), coming as close as 2.31 AU and reaching as far as 4.28 AU from the sun. Based on its brightness and the way it reflects light, 2003 SO159 is probably between 1.926 to 4.306 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.
2003 SO159's orbit is 1.31 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.
2003 SO159's orbit is determined by observations dating back to Feb. 20, 2001. It was last officially observed on April 4, 2019. The IAU Minor Planet Center records 199 observations used to determine its orbit.
