2013 TV135

On 16 October 2013, near-Earth asteroid {{mp|2013 TV|135}} (with a short observation arc of 7 days) was listed on the JPL Sentry Risk Table with 1 in 63,000 chance of impacting Earth on 26 August 2032. This gave the asteroid a Torino Scale rating of 1. The peak estimated threat from the asteroid occurred 19–20 October 2013 when Leonid Elenin and NEODyS estimated the odds of impact to be 0.03% (1 in 3,800). On 31 October 2013, NEODyS estimated the odds of impact to be 1 in 4,330 and the Sentry Risk Table estimated the odds of impact to be 1 in 6,250. On 7 November 2013, with a short observation arc of 25 days, the Sentry Risk Table estimated it had about a 1 in 169,492,000 chance of an Earth impact on 26 August 2032. It was removed from the JPL Sentry Risk Table on 8 November 2013 using JPL solution 32 with an observation arc of 27 days.

{{As of|2014|02|10|df=US}}, the NEODyS nominal best-fit orbit shows that {{mp|2013 TV|135}} will be {{convert|0.76|AU|km mi|abbr=on|lk=on}} from Earth on 26 August 2032.

File:ORBITA 2013 TV135.jpg

With an orbital inclination of only 6.7 degrees and perihelion 0.99 AU from the Sun, the point of perihelion is controlled by close approaches to Earth. With a short observation arc of 108 days, it has an orbit with an Uncertainty of 4. Given the relatively large size of the asteroid, astronomers were able to refine the orbit of this asteroid over several months.

An Earth impact would have the kinetic energy of 3,200 megatons of TNT, approximately 60 times the energy of Russia's 50 Mt Tsar Bomba. This would also be equivalent to 16 times the 1883 eruption of Krakatoa which was 200 Mt and had a Volcanic Explosivity Index of 6.
