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 ...
(53319) 1999 JM 8 is an asteroid, slow rotator and tumbler, classified as a near-Earth object and potentially hazardous asteroid (PHA) of the Apollo group, approximately 7 kilometers (4 miles) in diameter, making it the largest PHA known to exist. [12]
After the asteroid that wiped out the dinosaurs hit what is now the Yucatan Peninsula more than 30 million years before these asteroids, its explosive energy resulted in irreversible climate change.
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 ...
The relatively diminutive asteroid measured just 27 inches wide — about the diameter of a bicycle tire — and posed no danger to Earth, but was still enough to produce a “nice fireball in the ...
The first US mission sent to a near-Earth asteroid, OSIRIS-REx made history several times over. It performed the closest orbit of a planetary body by a spacecraft. Bennu became the smallest object ...
With an absolute magnitude of 15.8, [2] it is one of the brightest and therefore largest potentially hazardous asteroids (PHA) detected since (242450) 2004 QY 2. [8] The next largest PHA (based on absolute magnitude) discovered in 2011 is 2011 WO 41 with an absolute magnitude of 16.8.
