Small near-Earth asteroid February 2018 yes #FFC2E0 2012 FN Mount Lemmon Survey (G96) 17 March 2012 Apollo NEO 17 March 2012 (JD 2456003.5) 1.2214 AU Gm on 0.99291 AU Gm on 1.4500 AU Gm on on 0.18710 3.2329° 356.91° 147.89° 21.742° 1.35 yr (493.07 d) ~5 m 0 us 29.2 0.73012 ms /day 9 0.015601 AU Gm on 3.54794 AU Gm on 2012 FN is an Apollo asteroid and a near-Earth object that has a 1 in 4 billion chance of impacting Earth on 7 March 2113. It is estimated to be 5 meters in diameter, which means that it poses no threat if it impacts Earth. An impact would have the kinetic energy of about 3 kt of TNT, and would probably result in an air burst in the upper atmosphere. It is the least threatening asteroid listed on the Sentry Risk Table.Sentry Risk Table (NASA JPL) The very short observation arc of only 3 hours results in a very poorly constrained orbit, and it could just as easily be 2 AU from Earth on 7 March 2113.
