A Near Earth Object is an object in the solar system whose orbit comes extremely close to Earth.
Near Earth Objects are of many types.
1)Near Earth Asteroids.
2)Near Earth Comets.
3)Near Earth Meteoroids.
4)A number of solar-orbiting spacecrafts.
Near Earth Asteroids or the NEA have orbits ranging from 0.983 to 1.3 AU away from the Sun.
When an NEA is detected, it is submiteted to the Minor Planet Center (Located at the Harvard-Smithsonian Center for Astrophysics) for cataloging.
There is always a chance for Near Earth Asteroids to collide with Earth. NASA has a congressional mandate to catalogue all NEO's that are atleast 1 km wide as the impact of such an object would be catastrophic.As of Aug 2012, there have been 848 NEA's larger than 1 km and of which 154 are potentially hazardous asteroids (PHA's).
About 65 million years ago, an asteroid which was about 4-5 miles in diameter collided with Earth.
The collision generated immense heat and energy causing the end of the dinosaurs.
If such a collision happens again, it would generate such immense heat and energy causing a massive change in the climatic conditions.This would lead to a fall in the dominant species of the planet. Humans.
Yes. If an asteroid as big or bigger than that collides with Earth, that would be the end of the human legacy.
And, about a million NEO's are currently in space which can cause catastrophic damage.
These 11 Asteroids came seriously close to earth in the last year :
1) 2013 RZ53, September 18, 2013
2)(52760) 1998 ML14, August 24, 20133)(277475) 2005 WK4, August 8, 2013
4)2003 DZ15, July 30, 2013.
