Key Facts


Camilla is a very large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Camilla as potentially hazardous because its orbit does not bring it close to Earth.

Camilla orbits the sun every 2,380 days (6.52 years), coming as close as 3.26 AU and reaching as far as 3.71 AU from the sun. Camilla is about 210.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Maryland.

The rotation of Camilla has been observed. It completes a rotation on its axis every 4.84 hours.

Camilla's spectral type C (Tholen) / X (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.

No Close Approaches

Camilla's orbit is 2.29 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.

Images and Observations

Camilla's orbit is determined by observations dating back to Dec. 5, 1868. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 4,853 observations used to determine its orbit.
