367943 Duende

367943 Duende, also known by its provisional designation , is a near-Earth asteroid with an estimated diameter of . Before radar imaging, its estimated diameter was 45–50 meters.〔 During its 15 February 2013 close passage, Duende passed , 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.〔〔(【引用サイトリンク】url=http://www.nasa.gov/topics/solarsystem/features/russianmeteor.html )〕〔(【引用サイトリンク】title=Russian Asteroid Strike )
== Discovery and past risk assessments ==
Duende was discovered on February 23, 2012, by the Observatorio Astronómico de La Sagra, Granada Province in Spain (J75),〔 operated remotely by amateur astronomers in Mallorca,〔(【引用サイトリンク】title=Earth remains safe for now—but what about next asteroid? )〕 seven days after passing from Earth.〔 It was named after the duende, fairy- or goblin-like mythological creatures from Iberian, Latin American and Filipino folklore.〔(JPL SBDB )〕
Based on the still relatively imprecise orbit deduced from the short arc of the 2012 observations, there was a cumulative 0.033% risk estimate (1 in 3,030) of Duende impacting Earth sometime between 2026 and 2069.〔 It was already clear that Duende would pass no closer to Earth's surface than 3.2 Earth radii during its 2013 passage.〔 Eliminating an entry on the Sentry Risk Table is a negative prediction; a prediction of where it will ''not'' be.
