(163249) 2002 GT is an Apollo asteroid with an absolute magnitude of 18.26.[1] It is a potentially hazardous asteroid as its orbit crosses that of Earth.[2]
In 2011, it was reported that NASA scientists are considering the option of steering the currently retired space probe Deep Impact toward the asteroid with the aim of performing a flyby in 2020. It is not yet certain whether Deep Impact carries sufficient fuel for this operation.[3]
