While the Halloween party could boast of having been a comet, Christmas is going to have, meanwhile, an asteroid. Indeed, as of December 24, a space object measuring 2 km long, will pass close to the Earth and without representing any danger. A passage that is not so rare that, as explained Mark E. Bailey, the Observatory’s director implanted Armagh in Northern Ireland.
Sleep on your two ears: 2003 SD220 “is not on our list of risk objects” , says Maria-Antonietta Barucci, an astronomer at the Paris Observatory. “There is no danger, can be quiet, relaxed and enjoy Christmas” , provides specialist. The object is ten times smaller than the asteroid that caused the extinction of dinosaurs, agrees Mark E. Bailey, director of the Armagh Observatory in Northern Ireland. Far beyond the dead comet that was passed on October 31, Halloween day, about 500,000 km from us, or 1.3 times the distance separating Earth from the Moon.
An asteroid discovered 2003
The SD220 2003, is not new since it has been discovered by scientists in 2003 and will then move to 500 000 kilometers from Earth, or 28 times the distance which separates it from the moon. This represents a tiny distance scale of the universe. According to experts, many space objects pass close to the earth in the course of the year. And fortunately “ Christmas Asteroid ” There is no threat to us and to our environment.
Another asteroid is expected for 2029
A future asteroid grazing land is expected in 2029. The asteroid called Apophis will pass to a distance of about ten times less than the distance between the moon from the earth. Or, like the SD220 2003, this asteroid will represent no threat to our system.
This is the first of a series of five meetings between the asteroid and the Earth in the 12 coming years, as indicated by the Jet Propulsion Laboratory of NASA (JPL). The second meeting is scheduled for 2018 and the object will be much closer to Earth, at a distance of about 3 million kilometers.
Christmas can thus boast of having an asteroid pass few kilometers from the earth on the evening of December 24. Point of concern, however, in homes that can celebrate Christmas with family and without any hassle because that space object will only move to continue its path in the maze of space.
E study the deflection technology
collisions between Earth and space objects over 1 km in length occur about every 100,000 years, says Mark E. Bailey. There are 65 million years, the asteroid that caused the extinction of the dinosaurs (and even 75% of all known life forms, according to many experts) “was ten times bigger than in 2003 SD220,” he said . Experts keep repeating for years to come, there is no real danger or the less known collision between Earth and an asteroid.
But as we do not know all space objects, “you have to think, to work, keep looking objects,” explained Maria-Antonietta Barucci. “Above all, we must study the dangerous asteroid deflection technology and test, to be ready on D-Day.”
