2014 SC324 (also written 2014 SC324) is an Apollo near-Earth asteroid.[2] It was discovered on 30 September 2014 by the Mount Lemmon Survey at an apparent magnitude of 21 using a 1.5-meter (59 in) reflecting telescope.[1] With an absolute magnitude of 24.3,[2] the asteroid is about 37–85 meters in diameter.[3]

The preliminary orbit with a short observation arc of 2 days showed that the asteroid had a very small chance of passing 0.000125 AU (18,700 km; 11,600 mi) from the Moon or 0.0012 AU (180,000 km; 110,000 mi) from Earth on about 23 October 2014.[4] But with an observation arc of 10 days, the nominal (best fit) orbit showed that on 24 October 2014 the asteroid would pass 0.0038 AU (570,000 km; 350,000 mi) (1.5 LD) from Earth and even further from the Moon.[5] The asteroid peaked at apparent magnitude 13.5,[6] placing it in the range of amateurs with roughly 0.25-meter (10 in) telescopes.

It was removed from the Sentry Risk Table on 10 October 2014 using JPL solution #5 with a 10-day observation arc.[7]

It was observed by Goldstone radar on 24–25 October 2014.[8]
