Near Earth Objects and Impact Dangers

Learn more about near Earth objects and the impact dangers they pose. Discover what scientists are doing to spot meteorites, comets, and asteroids before they can endanger the Earth.

Revised Asteroid Scale Aids Understanding of Impact Risk - Revised Torino Scale
Astronomers led by an MIT professor have revised the scale used to assess the threat of asteroids and comets colliding with Earth to better communicate those risks with the public. The overall goal is to provide easy-to-understand information to assuage concerns about a potential doomsday collision with our planet.

NASA Announces Latest Asteroid Threat to Earth
A recently rediscovered 400-meter Near-Earth Asteroid (NEA) is predicted to pass near the Earth on 13 April 2029. The flyby distance is uncertain and an Earth impact cannot yet be ruled out. The odds of impact, presently around 1 in 300, are unusual enough to merit special monitoring by astronomers, but should not be of public concern. In all likelihood, the possibility of impact will eventually be eliminated as the asteroid continues to be tracked by astronomers around the world.

Near Earth Objects - Are We In Danger?
A commentary by Space Guide - Nick Greene. A recent article on BBC.com says that a small meteoroid (approximately 16 feet wide) flew past the Earth recently. It was the fourth closest pass by an object since we have been monitoring near Earth objects.

Asteroid 2003 QQ47 - Threat to Earth - Impact Potential in 2014
Although scientists have basically cleared us from any danger from asteroid 2002 NT7, which originally had been reported as an impact hazard for the year 2019, a newer space rock has been spotted, which may pose a threat even sooner. At around 1.2 km in width, 2003 QQ47 is substantially smaller than 2002 NT7 (2km), but has been called "an event meriting careful monitoring" by astronomers.

Asteroid 2002 NT7 - How Much Danger Does It Pose to Earth?
Is life imitating art? If you watched either of the 1998 movies Deep Impact or Armageddon, you may have an idea of the future that faces Earth... Or not.

Evidence Of Meteor Impact Found Off Australian Coast
An impact crater believed to be associated with the "Great Dying," the largest extinction event in the history of life on Earth, appears to be buried off the coast of Australia.

New Asteroid Threat to Earth - Impact Potential in 2014
Although scientists have basically cleared us from any danger from asteroid 2002 NT7, which originally had been reported as an impact hazard for the year 2019, a newer space rock has been spotted, which may pose a threat even sooner.

Quest Comes Through - Asteroid Hunters Discover Near-Earth Object
NASA astronomers in pursuit of near-Earth asteroids have already made a discovery with the newly installed Quasar Equatorial Survey, or 'Quest,' camera mounted in mid-April on Palomar Mountain's 1.2-meter (48-inch) Oschin telescope.
