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 ...
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 .
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.
A small asteroid was visible in northern Siberia on Tuesday, as it closed in on its collision course with Earth. The European Space Agency issued an alert for the 27-inch asteroid at 4:27 a.m. ET ...
Dinosaur enthusiasts know that an asteroid hitting Earth’s Yucatan Peninsula 66 million years ago—actually, let’s define terms first: an asteroid is a piece of rocky space debris that ...
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 that crashed into the Earth’s atmosphere over the UK and France was spotted just hours before it crashed. The world was given only seven hours warning that it was being approached by ...
