Dioretsa is a small asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified Dioretsa as potentially hazardous because its orbit does not bring it close to Earth.
Dioretsa orbits the sun every 42,686 days (116.87 years), coming as close as 2.40 AU and reaching as far as 45.40 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, Dioretsa is probably between 4.619 to 10.329 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the San Francisco Bay.
Dioretsa's orbit is 1.49 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.
Dioretsa's orbit is determined by observations dating back to June 16, 1998. It was last officially observed on Dec. 29, 2000. The IAU Minor Planet Center records 278 observations used to determine its orbit.
