An example list of near-Earth asteroids that passed more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2014.

  • (388188) 2006 DP14 (~300 meters in diameter) passed 6.2 lunar distances from Earth on 10 February 2014.
  • 2000 EM26 (~200 meters in diameter) passed more than 0.018 AU (2,700,000 km; 1,700,000 mi) from Earth on 17–18 February 2014.
  • 2014 KH39 (~25 meters in diameter) passed 1.1 lunar distances from Earth on 3 June 2014.[32]
  • 2014 HQ124 (~325 meters in diameter) passed 3.25 lunar distances from Earth on 8 June 2014.
  • 2014 OO6 (~75 meters in diameter) passed 0.0297 AU (4,440,000 km; 2,760,000 mi) from Earth on 18 August 2014.
  • 2014 XL7 (~230 meters in diameter) passed roughly 0.26 AU (39,000,000 km; 24,000,000 mi) from Earth on 1 September 2014.
  • The orbit of 2009 RR (20–45 meters in diameter) with an observation arc of only 4 days predicted that it could pass just inside 1 lunar distance on 2014-09-16, but the orbital uncertainties show that it could have passed as much as 0.1 AU (15,000,000 km; 9,300,000 mi) from Earth.[33]
  • 2014 SN142 (~10 meters in diameter) passed 1.1 lunar distances from Earth on 23 September 2014.[34]
  • 2014 SC324 (~60 meters in diameter) passed 1.5 lunar distances from Earth on 24 October 2014.[35]
