4179 Toutatis (provisional designation 1989 AC) is an elongated, stony asteroid and slow rotator, [11] classified as a near-Earth object and potentially hazardous asteroid of the Apollo asteroid group, approximately 2.5 kilometers in diameter.
The asteroid Toutatis is listed as a potentially hazardous near-Earth asteroid, yet poses no immediate threat to Earth.(Radar image taken by GDSCC in 1996.)A potentially hazardous object (PHO) is a near-Earth object – either an asteroid or a comet – with an orbit that can make close approaches to the Earth and which is large enough to cause significant regional damage in the event of ...
Clementine 2 was a proposed asteroid-interception mission that was intended to fly by two near-Earth asteroids, 433 Eros and 4179 Toutatis planned by NASA. [2]The probe impact at Toutatis was needed to obtain the dynamic strength of surface material and data on the properties of the regolith and on stratification below the surface, and potentially allowed the measurement of thermal diffusivity ...

Toutatis imaged by Chang'e 2 during its flyby. According to Ouyang Ziyuan's report to the 16th Conference of the Chinese Academy of Sciences, Chang'e 2 departed from L2 on 15 April 2012, and began a mission to the asteroid 4179 Toutatis. [33] The flyby was successfully achieved on 13 December 2012 at 16:30:09 Beijing Time (08:30:09 GMT). [34]

Asteroid 2004 XP 14 was the closest potentially hazardous asteroid, passing Earth by 432,308 km (268,624 mi), 0.00289 AU, or just 1.1 times the Moon's average distance from Earth on 3 July 2006. Asteroid 4179 Toutatis (4.5 km diameter) came within 1.5 million km, 0.0104 AU (within 4 lunar distances) of the Earth on 29 September 2004.
