Bellona is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Bellona as potentially hazardous because its orbit does not bring it close to Earth.
Bellona orbits the sun every 1,690 days (4.63 years), coming as close as 2.36 AU and reaching as far as 3.20 AU from the sun. Bellona is about 120.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Connecticut.
The rotation of Bellona has been observed. It completes a rotation on its axis every 15.71 hours.
Bellona's spectral type S (Tholen) / S (SMASSII) indicates that it is likely to contain and .
Bellona's orbit is 1.37 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.
Bellona's orbit is determined by observations dating back to Sept. 29, 1856. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,537 observations used to determine its orbit.
