Asteroid isn't just a dry heap of rubble - 0 views

  •  
    Two teams have found evidence of water ice on the asteroid 24 Themis; the find suggests asteroids could have delivered some water to the early Earth

Asteroid Deflection by Tether - 0 views

  •  
    Diverting incoming asteroids is a high priority item, and so is a mission to a nearby asteroid for a close-up study of its composition and a shakeout of operating technologies.

NASA - The Impact and Recovery of Asteroid 2008 TC3 - 0 views

  •  
    The Impact and Recovery of Asteroid 2008 TC3.\nNASA detects and tracks asteroids and comets passing close to Earth. The Near-Earth Object Observation Program, commonly called "Spaceguard," discovers, characterizes and computes trajectories for these objects to determine if any could be potentially hazardous to our planet. \n\n

Spitzer observations of the asteroid-comet transition object and potential spacecraft ... - 0 views

  •  
    Near-Earth asteroid-comet transition object 107P/ (4015) Wilson-Harrington is a possible target of the joint European Space Agency (ESA) and Japanese Aerospace Exploration Agency (JAXA) Marco Polo sample return mission. Physical studies of this object are relevant to this mission, and also to understanding its asteroidal or cometary nature.

NASA - Hubble Sees Suspected Asteroid Collision - 0 views

  •  
    NASA's Hubble Space Telescope has observed a mysterious X-shaped debris pattern and trailing streamers of dust that suggest a head-on collision between two asteroids. Astronomers have long thought that the asteroid belt is being ground down through collisions, but such a smashup has never been seen before.

Solar wind tans young asteroids - 0 views

  •  
    A new study published in Nature this week reveals that asteroid surfaces age and redden faster than previously thought - in less than a million years, the blink of an eye for an asteroid.

Asteroids won't raise killer waves - but mind the splash - 0 views

  •  
    New simulations suggest the monster waves created by a small asteroid impact would break before they reached land, but you still wouldn't want to be near

Nearby asteroid found orbiting sun backwards - 0 views

  •  
    The discovery of a 2- to 3-kilometre-wide asteroid in an orbit that goes backwards has set astronomers scratching their heads. It comes closer to Earth than any other object in a 'retrograde' orbit, and astronomers think they should have spotted it before.

Small Asteroid 2009 VA Whizzes By The Earth - 0 views

  •  
    A newly discovered asteroid designated 2009 VA, which is only about 7 meters in size, passed about 2 Earth radii (14,000 km) from the Earth's surface Nov. 6 at around 16:30 EST. This is the third-closest known (non-impacting) Earth approach on record for a cataloged asteroid.

2009 HC82: A Burnt-Out, Eccentric and Backward Near-Earth Asteroid - 0 views

  •  
    The Solar System often throws up surprises for astronomers, but the recent discovery of a 2- to 3-km wide asteroid called 2009 HC82 has sent observers in a spin. A retrograde spin to be precise.

How Will We Prepare for an Asteroid Impact? - 0 views

  •  
    If Earthlings discovered a large asteroid heading towards our planet, how would we react? But more importantly would the space agencies and/or world governments be prepared for such an event?

Arxiv - Fuzzy Characterization of Near-Earth-Asteroids - 0 views

  •  
    Due to close encounters with the inner planets, Near-Earth-Asteroids (NEAs) can have very chaotic orbits. Because of this chaoticity, a statistical treatment of the dynamical properties of NEAs becomes difficult or even impossible. We propose a new way to classify NEAs by using methods from Fuzzy Logic.

Asteroid killed off the dinosaurs, says international scientific panel - 1 views

  •  
    The Cretaceous-Tertiary mass extinction, which wiped out the dinosaurs and more than half of species on Earth, was caused by an asteroid colliding with Earth and not massive volcanic activity, according to a comprehensive review of all the available evidence." id="metasummary
