The exceptionally fast rotator passed within 0.000267 AU km mi on on (0.1 lunar distances) of Earth on 7 September 2014. The asteroid is approximately the diameter of the Chelyabinsk meteor, and passed almost as close to Earth as 367943 Duende (2012 DA 14) did in 2013. With an absolute magnitude of 26.8, the asteroid is about 11 - 25 m ft us in diameter depending on the albedo. Observations by the NASA Infrared Telescope Facility conclude the asteroid is a fairly bright Sq-class asteroid which have an average albedo of around 0.24, and would give the asteroid a spherical equivalent diameter of 12 m ft us. Measurements by multiple telescopes indicate that the asteroid rotates in 15.8 seconds making it one of the fastest rotating asteroids so far discovered. Using the 15.8 second rotation period, more accurate radar observations by Goldstone shows the asteroid has a largest axis of at least 22 m ft us. Due to the asteroid's fast rotation, it is a monolith and not a rubble pile. On 8 September 2115 the asteroid will pass about 0.0053 AU km mi on on from the Moon. On 5 September 1973, the asteroid passed between 0.01052 AU km mi on off and 0.01207 AU km mi on off from Earth. 2014 RC was removed from the JPL Sentry Risk Table on 5 September 2014 and there are no known possible impact dates in the next 100 years. 2014 approach It made a close approach to Earth of 0.000267 AU km mi on on (0.1 LD) around 18:02 UTC on 7 September 2014. The asteroid briefly brightened to about apparent magnitude 11.5, but it was still not visible to the naked eye or common binoculars. At the peak brightness the asteroid had a declination of –47, and was most easily visible over New Zealand. During 2014, asteroids 2014 AA and 2014 LY 21 have come closer to Earth. center Asteroid 2014 RC 600 Asteroid-2014RC-20140903b.jpg Path around the Sun 3 September 2014.

The Managua explosion on 6 September 2014 may or may not have been created by a bolide that was missed by millions of people, but either way it was not caused by the close approach of 2014 RC. Orbital shift During the 2014 Earth close approach the orbital period of 2014 RC was reduced from 600 days to 549 days. The orbital eccentricity decreased while the orbital inclination increased.
