Dynamicists believe a large meteoroid broke apart as it passed over Ireland on the night of September 21, 2012. Slowed by its atmospheric passage, the object entered a temporary orbit around Earth and returned to the sky over eastern North America 155 minutes later.Amazing Meteor Boomerangs Around EarthFor the first time ever, a meteor has grazed in and out of Earth's atmosphere, slowing enough to become a temporary satellite that lasted a full orbit.
Friday-night crowds were out and about when the bolide appeared, delighting and amazing untold thousands as it broke into dozens of pieces as it glided east to east across the sky. Dirk Ross, who tracks bright meteors and meteorite finds worldwide, logged 564 eyewitness reports from England, Scotland, Ireland, France, Belgium, The Netherlands, and Norway.
A few hours later, Ross received another burst of 126 sightings. But these weren't from Europe instead, a fireball had appeared over southeastern Canada and the U.S. Northeast. What at first seemed the unlikely arrival of two dramatic bolides in a single night is now known to be something much more historic and scientifically profound.
Mathematician Esko Lyytinen, a member of the Finnish Fireball Working Group of the Ursa Astronomical Association, has analyzed both sets of sightings and concludes that the two events resulted from a single object encountering Earth that night. He believes a large body grazed the upper atmosphere, dipping to an altitude of 33 miles (53 km) over Ireland before escaping back to space. Because it arrived moving at only about 8 miles (13 km) per second, barely above Earth's escape velocity, it lingered for more than a minute as it crossed the sky. (This explains why some witnesses mistook it for reentering spacecraft debris.)
