Robel is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Robel as potentially hazardous because its orbit does not bring it close to Earth.
Robel orbits the sun every 1,600 days (4.38 years), coming as close as 2.41 AU and reaching as far as 2.96 AU from the sun. Based on its brightness and the way it reflects light, Robel is probably between 5.735 to 12.824 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
The rotation of Robel has been observed. It completes a rotation on its axis every 12.13 hours.
Robel's orbit is 1.41 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.
Robel's orbit is determined by observations dating back to Oct. 21, 1992. It was last officially observed on Dec. 25, 2022. The IAU Minor Planet Center records 3,206 observations used to determine its orbit.
