    The asteroid had a close approach to the Earth on 29 May 2012, approaching to only ~8950 miles (~14,440 km) above the planet's surface. This means 2012 KT 42 came inside the Clarke Belt of geosynchronous satellites. In May 2012, the estimated 5- to 10-metre-wide asteroid ranked #6 on the top 20 list of closest-approaches to Earth.

    Toutatis has been observed with radar imaging from the Arecibo Observatory and the Goldstone Solar System Radar during the asteroid's prior Earth flybys in 1992, 1996, 2000, 2004, and 2008. It was also observed with radar during the December 2012 flyby and observed more distant flyby with radar in December 2016. [29]

    en.wikipedia.org/wiki/2012_TC4

    During the 2012 close approach, the asteroid only had an observation arc of 7 days, between 4 and 11 October 2012, so the exact distance of the 2017 closest approach was poorly constrained. With the 7 day observation arc, the asteroid had a 3-sigma chance of passing between 0.00008818 and 0.002896 AU (0.034 to 1.127 LD , 13,200–433,200 km ...

    The flyby was successfully achieved on 13 December 2012 at 16:30:09 Beijing Time (08:30:09 GMT). [34] Close-up images of the asteroid, with a resolution of up to 10 metres (33 ft) per pixel, were later published online. [35] The flyby was the first time an uncrewed spacecraft had imaged the asteroid so closely. Chang'e 2 came as close as 3.2 ...
