Key Facts

Overview

Corduba is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Corduba as potentially hazardous because its orbit does not bring it close to Earth.

Corduba orbits the sun every 1,710 days (4.68 years), coming as close as 2.36 AU and reaching as far as 3.24 AU from the sun. Corduba is about 86.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.

The rotation of Corduba has been observed. It completes a rotation on its axis every 12.71 hours.

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

No Close Approaches

Corduba's orbit is 1.38 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

Corduba's orbit is determined by observations dating back to March 22, 1893. It was last officially observed on March 13, 2023. The IAU Minor Planet Center records 4,492 observations used to determine its orbit.
