It is a potentially hazardous asteroid as its orbit crosses that of Earth.Stephen Clark, "Deep Impact sets path for asteroid encounter in 2020". Spaceflight Now. 18 December 2011. Description In 2011, NASA considered sending the unmanned spacecraft Deep Impact toward the asteroid with the aim of performing a flyby in 2020. It was uncertain whether Deep Impact carried sufficient fuel for this operation. On 24 November 2011 and 4 October 2012, the space probe's thrusters were fired briefly for two trajectory correction maneuvers that targeted Deep Impact for an encounter with 2002 GT in 2020, possibly within a distance of about 200 kilometers. However, funding for the flyby mission was not guaranteed.Emily Lakdawalla http://www.planetary.org/blogs/emily-lakdawalla/2012/10051022-deep-impact-asteroid-flyby.html Deep Impact targets possible 2020 asteroid flyby 5 October 2012 Deep Impact's possible January 4, 2020 flyby would be a nice one, at a close-approach distance of around 200 kilometers and a relative velocity of 7 kilometers per second. That's both closer and slower than the Hartley 2 flyby (which was at 700 kilometers and 12 kilometers per second). In June 2013 the asteroid was observed in radar by the Arecibo Observatory.Asteroid and Comet Mission Targets Observed by Radar (archived version, 19 Dec 2013) However, on 8 August 2013 NASA lost communication with the spacecraft, and on 20 September 2013, NASA abandoned further attempts to contact the craft.NASA calls off search for lost Deep Impact comet probe - Australian Broadcasting Corporation - Retrieved 21 September 2013.
