Seryozha is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Seryozha as potentially hazardous because its orbit does not bring it close to Earth.
Seryozha orbits the sun every 1,750 days (4.79 years), coming as close as 2.60 AU and reaching as far as 3.08 AU from the sun. Based on its brightness and the way it reflects light, Seryozha is probably between 5.896 to 13.184 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
Seryozha's orbit is 1.60 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.
Seryozha's orbit is determined by observations dating back to Oct. 31, 1953. It was last officially observed on June 13, 2023. The IAU Minor Planet Center records 3,196 observations used to determine its orbit.
