It was first observed on 19 December 2012, by astronomers Andrey Oreshko and Timur Kryachko at the Elena Remote Observatory (G32) located in the Chilean Atacama desert. Description With a 4-day observation arc, the asteroid had a 1 in 3 million chance of impacting in 2106. With a 10-day observation arc, the asteroid had a 1 in 10 million chance of impacting in 2106. On 5 January 2013, the asteroid passed 0.10 AU km mi on on from Earth. It was removed from the Sentry Risk Table on 8 January 2013. It had an observation arc of 32 days and an orbital uncertainty of 7. Since the asteroid had a poorly known orbit, the cone of uncertainty quickly multiplied as a result of perturbations by the inner planets and prevented precise/reliable ephemeris data. Eliminating an entry on the Sentry Risk Table is a negative prediction; a prediction of where it will NOT be. With MPEC 2024-C131 the Minor Planet Center published a newly computed orbit on 12 February 2024, using observations till 12 November 2023 and prediscovery observations from 31 May till 5 June 2010, reducing the uncertainty to 1. In the popular press In 2013, an article, originally posted on The Voice of RussiaZamanskaya Yulia 2013-02-08 We have 93 years left till the next End of the World: killer asteroid to hit Earth in 2106: Voice of Russia http://english.ruvr.ru/2013_02_05/We-have-93-years-left-till-the-next-End-of-the-World-killer-asteroid-to-hit-Earth-in-2106/ https://web.archive.org/web/20130208031058/http://english.ruvr.ru/2013_02_05/We-have-93-years-left-till-the-next-End-of-the-World-killer-asteroid-to-hit-Earth-in-2106/ 2013-02-08 2023-10-08 english.ruvr.ru had a poorly researched headline stating "We have 93 years left till the next End of the World". This story was reposted on Space Daily, but then astronomer Phil Plait clarified that it was "a fascinating mix of fact and error. A lot of what it says is accurate, but the most important claim—that an asteroid will impact Earth in 2106—is simply wrong."Slate No, An Asteroid Is NOT Going to Hit Earth in 2106 Phil Plait 13 Feb 2013 http://www.slate.com/blogs/bad_astronomy/2013/02/13/asteroid_impact_2106_reports_of_a_space_rock_hitting_us_are_exaggerated.html thumb|left|250x250px|Orbits of a typical PHA (potentially hazardous asteroid) and NEA (Near-Earth Asteroid). left See also Torino scale Palermo scale References 2013-07-04 last obs.
