2013 TV135 is an Apollo near-Earth asteroid estimated to have a diameter of 450 meters (1,480 ft). On September 16, 2013, it passed about 0.0448 AU (6,700,000 km; 4,160,000 mi) from Earth. On September 20, 2013, it came to perihelion (closest approach to the Sun). The asteroid was discovered on October 12, 2013 by the Crimean Astrophysical Observatory using images dating back to October 8, 2013. It was discovered by Ukrainian astronomer Gennady Borisov with a custom 0.2-meter (7.9 in) telescope. It was rated level 1 on the Torino Scale from October 16, 2013 until JPL solution 26 on November 3, 2013. It was removed from the JPL Sentry Risk Table on November 8, 2013 using JPL solution 32 with an observation arc of 27 days.

Past Earth-impact estimates
On October 16, 2013, near-Earth asteroid 2013 TV135 (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 August 26, 2032. This gave the asteroid a Torino Scale rating of 1. The peak estimated threat from the asteroid occurred October 19–20, 2013 when Leonid Elenin and NEODyS estimated the odds of impact to be 0.03% (1 in 3,800). On October 31, 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 November 7, 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 August 26, 2032. It was removed from the JPL Sentry Risk Table on November 8, 2013 using JPL solution 32 with an observation arc of 27 days.
As of February 10, 2014, the NEODyS nominal best-fit orbit shows that 2013 TV135 will be 0.76 AU (114,000,000 km; 71,000,000 mi) from Earth on August 26, 2032.
Orbit
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.
Impact effects
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.
