Near-Earth object / ID: 2001620
1620 Geographos 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 2.3km - 5.2km across. It has been followed since 1951-09-14 across 10368 recorded observations. Its next approach to Earth is 2040-Mar-12 10:58, passing at 44.205 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.
