(501647) 2014 SD224 is an Aten near-Earth asteroid around 150 meters (490 feet) in diameter. It was discovered on 22 September 2014 when the asteroid was 0.29 AU (43 million km; 110 LD) from Earth and had a solar elongation of 123 degrees. The glare of the Sun had masked the approach of the asteroid as it passed closest approach to Earth on 11 August 2014.[2][a] The asteroid now has a 6-year observation arc and a well-determined orbit. It also makes close approaches to Venus.
