It was like any other Friday except for that incredibly insane, I can’t believe that happened, Russian meteorite. That thing, on the same day as the DA14 was whizzing by Earth, seemingly came out of nowhere, crashing through our atmosphere at incredible speeds before the bolide. So where the heck did that come from?
Scientists think they know.
After collecting as much information as possible—dash cam footage, CCTV footage, Meteosat-9 weather satellite data—two scientists from the University of Antioquia in Medellin, Columbia say the space rock originated from an Apollo-class asteroid.
“Apollo-class asteroids are well-known near-Earth asteroids that cross the orbit of Earth,” Discovery explained. “Around 5,200 Apollo asteroids are currently known, the largest being 1866 Sisyphus—a 10 kilometer-wide monster that was discovered in 1972.”
The two scientists were even able to chart the Russian meteor’s exact path using astronomy software called Naval Observatory Vector Astrometry Software (NOVAS). Overall, the city of Chelyabinsk, where the meteorite supposedly struck an icy lake, reported 1,500 injuries cause by the powerful sonic boom.
Hopefully in the future we can actually chart these things before they happen, rather than figuring out where these armageddon rocks came from.
