13228 (1997 SJ25) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1997 SJ25 as potentially hazardous because its orbit does not bring it close to Earth.
1997 SJ25 orbits the sun every 2,060 days (5.64 years), coming as close as 2.65 AU and reaching as far as 3.68 AU from the sun. 1997 SJ25 is about 12.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.
The rotation of 1997 SJ25 has been observed. It completes a rotation on its axis every 25.39 hours.
1997 SJ25's orbit is 1.64 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.
1997 SJ25's orbit is determined by observations dating back to Sept. 15, 1991. It was last officially observed on May 21, 2023. The IAU Minor Planet Center records 3,300 observations used to determine its orbit.
