128209 (2003 SS65) 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 SS65 as potentially hazardous because its orbit does not bring it close to Earth.
2003 SS65 orbits the sun every 2,910 days (7.97 years), coming as close as 3.38 AU and reaching as far as 4.60 AU from the sun. 2003 SS65 is about 8.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of 2003 SS65 has been observed. It completes a rotation on its axis every 18.46 hours.
2003 SS65's orbit is 2.38 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 SS65's orbit is determined by observations dating back to April 28, 1992. It was last officially observed on April 16, 2023. The IAU Minor Planet Center records 896 observations used to determine its orbit.
