• 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]
