Near-Earth object / ID: 2004660
4660 Nereus 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 473m - 1.1km across. It has been followed since 1981-09-30 across 5002 recorded observations. Its next approach to Earth is 2031-Mar-02 07:55, passing at 44.758 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.
