Sonja is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Sonja as potentially hazardous because its orbit does not bring it close to Earth.
Sonja orbits the sun every 1,210 days (3.31 years), coming as close as 1.61 AU and reaching as far as 2.84 AU from the sun. Sonja is about 7.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of Sonja has been observed. It completes a rotation on its axis every 2.88 hours.
Sonja's spectral type None (Tholen) / Sq (SMASSII) indicates that it is likely to contain and .
Sonja's orbit is 0.62 AU from Earth's orbit at its closest point. This means that there is a very 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.
Sonja's orbit is determined by observations dating back to Sept. 26, 1933. It was last officially observed on Aug. 16, 2022. The IAU Minor Planet Center records 3,136 observations used to determine its orbit.
