Near-Earth object / ID: 2002102
2102 Tantalus is a near-Earth object of the APO orbit class — Near-Earth asteroid orbits which cross the Earth’s orbit similar to that of 1862 Apollo. Radar and photometric estimates put it between 1.7km - 3.8km across. It has been followed since 1976-01-02 across 2349 recorded observations. Its next approach to Earth is 2038-Dec-27 07:34, passing at 17.270 LD. JPL classifies it as a potentially hazardous asteroid, a label driven by its size and how close its orbit comes to ours — not by a predicted impact.
