Near-Earth object / ID: 2002101
2101 Adonis 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 486m - 1.1km across. It has been followed since 1936-02-21 across 155 recorded observations. Its next approach to Earth is 2035-Nov-26 06:20, passing at 13.305 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.
