As we have recently been reading the opening is important, however endings can make or break a story.
Scientists reconstruct Russian meteor trajectory




Scientists reconstruct Russian meteor trajectory
In a paper published online at arXiv.org, Zuluaga and Ferrin took Geen's analysis further, using a gravitational analysis to reconstruct the path of the rock going back four years before impact. Their analysis indicates that the meteor was one of the Apollo asteroids, a class of space rocks whose elongated orbits occasionally cross that of our planet. There are about 5,200 known Apollo asteroids, the largest of them being 1866 Sisyphus, a six-mile wide rock discovered in 1972. Sisyphus is comparable in size to the impactor thought to have caused a global extinction event some 66 million years ago, ending the age of the dinosaurs.
In an effort to prevent a repeat of this sort of event, European Space Agency officials announced a plan to smash a spacecraft into an Apollo asteroid in 2022 to alter its orbit, just for practice. The target of the joint European/US Asteroid Impact and Deflection Assessment mission, a rock named 65803 Didymos, poses no threat to our planet in the foreseeable future, unless of course the mission goes seriously wrong and Didymos is knocked into our path.
