2013 TV135
is an Apollo near-Earth asteroid and potentially hazardous object estimated to have a diameter of. On 16 September 2013, it passed about from Earth. On 20 September 2013, it came to perihelion. The asteroid was discovered on 12 October 2013 by Ukrainian amateur astronomer Gennadiy Borisov with a custom telescope using images dating back to 8 October 2013. It was rated level 1 on the Torino Scale from 16 October 2013 until JPL solution 26 on 3 November 2013. It reached a Palermo scale rating of -0.73. It was removed from the JPL Sentry Risk Table on 8 November 2013 using JPL solution 32 with an observation arc of 27 days.
Past Earth-impact estimates
On 16 October 2013, near-Earth asteroid 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%. 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., the NEODyS nominal best-fit orbit shows that will be from Earth on 26 August 2032.
