367943 Duende, also known by its provisional designation 2012 DA14, is an Aten near-Earth asteroid with an estimated diameter of 30 meters (98 ft). Before radar imaging, its estimated diameter was 45–50 meters. During its 15 February 2013 close passage, Duende passed 27,700 km (17,200 mi), or 4.3 Earth radii, from Earth's surface. This is a record close approach for a known object of this size. About 16 hours before the closest approach of Duende, an asteroid entered Earth's atmosphere above Russia, which was, however, unrelated to it because it had a completely different orbit.
