Near-Earth object / ID: 2003122
3122 Florence is a near-Earth object of the AMO orbit class — Near-Earth asteroid orbits similar to that of 1221 Amor. Radar and photometric estimates put it between 4.1km - 9.1km across. It has been followed since 1979-03-09 across 10321 recorded observations. Its next approach to Earth is 2057-Sep-02 00:41, passing at 19.434 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.
