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

Live Chat With NASA's Asteroid Trackers: The live event will air on the "NASAJPL" channel available on Ustream TV at: http://www.ustream.tv/channel/nasajpl on March 25 at 4:30 p.m. PDT (7:30 p.m. EDT and 23:30 UTC).

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.

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.

Millions of asteroids are winging around the solar system, but which ones do we have to fear? Browse these images of our ominous neighbors to find out.

'Noise' from the LISA mission will give scientists a way to study the mass and number of near-Earth asteroids.

NASA's WISE mission has spotted 16 near-Earth objects that had previously been hidden in the dark

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.
