Scientists Reconstruct (Russian) Meteor's Journey To Earth
Scientists have reconstructed the orbit of the meteor that blazed across the Russian sky earlier this month.
After entering the Earth's atmosphere, the meteor is thought to have travelled hundreds of miles before exploding above Chelyabinsk.
The reconstruction is designed to illustrate how the body of the meteor came to shower fragments of rock over a large area of Western Siberia.
The video plots the orbits of Earth, Mars and the meteor itself in the period prior to its encounter with our planet.
Physicists at the University of Antioquia in Colombia used evidence from a CCTV camera in Revolution Square, Chelyabinsk, as well as witnesses in the nearby city of Korkino, to chart its progress across the Russian sky.
