Amazing Meteor Boomerangs Around Earth

For 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.


2012's
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.
S&T: J. Kelly Beatty
By evening on September 21st, an earlier storm had moved eastward and left skies over the British Isles beautifully clear.

Martin Goff, an officer with the Greater Manchester [England] Police, was making his rounds when he spotted a dazzling meteor at 22:55 p.m. (21:55 Universal Time). "I immediately pulled the van over to better see the fireball," he recounts. "Although not an experienced astronomical observer I was able to log relevant information such as altitude and azimuth relative to the straight road I was on and to trees and streetlights nearby." He estimates it was about as bright as a full moon and remained visible for 35 to 40 seconds, fragmenting for at least the last half of that. "I was just flabbergasted to have seen it!"

He was hardly alone in his amazement. 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.

  1. This isn’t the first time this has happened though. The first documented boomerang event occurred on the 8th October 1996 over Northern New Mexico. A fireball was seen entering the atmosphere and partially broke up, but skipped back out. Its encounter with the atmosphere was enough to slow its velocity such that it entered a temporary orbit, and about 100 mins later it re-entered the atmosphere, this time of the coast of California, where it then burned up in the atmosphere. Details can be found in the Paper Back version of Lewis Spence’s “Rain of Ice and Fire” (in the afterword), or in his other book “Comet and Asteroid Impact Hazards on a Populated Earth: Computer Modelling”.
