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 ...
An asteroid streaked past northern Siberia in the middle of the night Tuesday before burning up in Earth's atmosphere, lighting up the skies with a blinding flash, dramatic video shows.
(308635) 2005 YU 55, provisionally named 2005 YU 55, is a potentially hazardous asteroid [2] 360 ± 40 meters in diameter, as measured after its Earth flyby. [8] Previously it was estimated to be 310 meters [5] or about 400 m (1,300 feet) in diameter.
The fossils were between 35.5 to 35.9 million years old and were found in a nearly 10-foot-long rock core: a tube-like sample taken from underneath the Gulf of Mexico by the scientific Deep Sea ...
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.
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024 [update] , all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors .
