2012 TV is a near-Earth Apollo asteroid with an estimated diameter of 30 metres (98 ft).[2] Its closest approach to the Earth was on October 7, 2012, with a distance of 0.0017 astronomical units (250,000 km; 160,000 mi).[3] It also approached the Moon an hour earlier with a distance of 0.0028 astronomical units (420,000 km; 260,000 mi).[3] With a short observation arc of 1.8 days, the asteroid is listed on the Sentry Risk Table and has a 1:500,000 chance of impacting Earth on April 2, 2081.[2]
As it will come to perihelion in mid-February 2022, it will be approaching Earth from the direction of the Sun. The closest approach possible during April 2022 is 0.66 LD (250,000 km), but it is expected to pass millions of kilometers from Earth.[3]
