Castel Gandolfo is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Castel Gandolfo as potentially hazardous because its orbit does not bring it close to Earth.
Castel Gandolfo orbits the sun every 1,950 days (5.34 years), coming as close as 2.35 AU and reaching as far as 3.76 AU from the sun. Based on its brightness and the way it reflects light, Castel Gandolfo is probably between 2.092 to 4.678 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.
Castel Gandolfo's orbit is 1.36 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.
Castel Gandolfo's orbit is determined by observations dating back to Dec. 30, 1954. It was last officially observed on June 25, 2023. The IAU Minor Planet Center records 596 observations used to determine its orbit.
