Asteroid 2012 TC4 was discovered by F51 Pan-STARRS 1, Haleakala on images taken on 2012, Oct. 04.4 with a 1.8-m Ritchey-Chretien + CCD. Just eight days after its discovery, on 2012 Oct. 12, this object passed at about 0.25 LD from Earth. After exactly 5 years, 2012 TC4 will have a new close approach with our planet that will provide astronomers with a valuable opportunity to learn more about its orbit and composition and to test the network of observatories and scientists who work with planetary defense. See below for the details.

This asteroid was not observed since the week it was discovered in October 2012 and it has been recovered by astronomers using one of the European Southern Observatory's 8.2-meter telescopes at the Very Large Telescope (VLT) on July 27, 2017 at an apparent magnitude of 26.8 (making it the faintest Near Earth Asteroid so far measured).Credit: ESO/ESA NEOCC/Hainaut (ESO), Micheli (ESA) & Koschny (ESA)2012 TC4 has an estimated size of 12 m - 27 m (H=26.7) and ...
