Near-Earth Asteroids, say what?
There are over 20,000 known Near-Earth asteroids (NEA). Most of these Asteroids orbit in the region between Mars and Jupiter. Near Earth Objects (NEO’s) have become of increased interest since the 1980s because of greater awareness of the potential danger.
When orbits of some of the NEO’s intersect that of the earth, there is a possibility of the collision and can cause a significant damage -hence are classified as Potentially Hazardous Objects (PHO) or Asteroids (PHA).
You should not be too much concerned about the earth being hit by NEO’s, as this threat is very small compared to the threats from diseases and accidents on roads.
NASA and other institutions around the world are trying their best to develop an efficient defense system to protect our earth from the risk of a NEO collision.
For any efficient defense system we need to
1. Detect the PHA’s
2. Track and characterize PHA’s
3. Know when and how to deflect a threatening asteroid.
Where are Near-Earth Asteroids? Track Live*!
SpaceIn3D.com provides 3D orbits for all of the asteroids arriving Near-Earth. Live* tracking info is available for asteroids, space objects, comets and select space missions. 3D Near-Earth Asteroid (NEA) tracking is free and available right from the comfort of your browser. It contains a database of 1,000,000 objects that can be searched and added to the 3D Live Simulation Tracker. Would you like to have a go at assessing the risk of impact yourself? Or verify the collision risk of Near-Earth Objects (NEO)? – see spacein3d.com
