'''{{mp|2014 SC|324}}''' is a sub-kilometer [[asteroid]] and [[List of fast rotators (minor planets)|fast rotator]], classified as a [[near-Earth object]] of the [[Apollo asteroid|Apollo group]], approximately 50 meters in diameter.<ref name=jpldata/> It was first observed on 30 September 2014, by the [[Mount Lemmon Survey]] at an [[apparent magnitude]] of 21 using a {{convert|1.5|m|in|adj=on|sp=us}} [[reflecting telescope]].<ref name="MPEC2014-T10"/> With an [[Absolute magnitude#Solar System bodies (H)|absolute magnitude]] of 24.3,<ref name=jpldata/> the asteroid is about 37–85&nbsp;meters in diameter.<ref name="h"/>

== Description ==
The preliminary orbit with a short [[observation arc]] of 2 days showed that the asteroid had a very small chance of passing {{convert|0.000125|AU|km mi|abbr=on|lk=on}} from the Moon or {{convert|0.0012|AU|km mi|abbr=on|lk=off}} from Earth on about 23 October 2014.<ref name="archive141002"/> But with an observation arc of 10 days, the [[Curve fitting|nominal]] (best fit) orbit showed that on 24 October 2014 the asteroid would pass {{convert|0.0038|AU|km mi|abbr=on|lk=off}} (1.5&nbsp;[[Lunar distance (astronomy)|LD]]) from Earth and even further from the Moon.<ref name=jpl-close/> The asteroid peaked at [[apparent magnitude]] 13.5,<ref name="NEODyS2014"/> placing it in the range of amateurs with roughly {{convert|0.25|m|in|0|adj=on|sp=us}} telescopes.

It was removed from the [[Sentry (monitoring system)|Sentry Risk Table]] on 10 October 2014 using JPL solution #5 with a 10-day observation arc.<ref name="removed"/>

It was observed by [[Goldstone Deep Space Communications Complex|Goldstone]] [[radar astronomy|radar]] on 24–25 October 2014.<ref name="Goldstone"/>
