According to Louis of Hendecourt, CNRS research director at the Institute of Space Astrophysics, interviewed by the newspaper Sud Ouest, the green color of the meteor mentioned by many users is due to its composition, including “the presence of minerals that vaporize and emit light “ .
This fireball “skimming” , which followed a trajectory of an inclination of 20 °, is passed over the southwest of France and has “gone vertical Perigueux at a height of 37 km ‘ , depending on network knave, whose fifteen cameras have been seen.
“It happened quite slowly, at a speed of 18 km/s, it was evident when he was at 80 km altitude. It is almost certain that disintegrated before reaching the ground “ , said François Colas.
A dozen meteorites fall every year in France
According to the IMO, the meteor was visible for seven seconds in a race of about 120 km between the towns of Bruniquel (Tarn-et-Garonne) and Peyzac-le-Moustier (Dordogne).
“The original fireball was estimated to be between 10 and 20 or 30 centimeters in diameter, small enough that it disappears completely. For to have a meteorite (which affects earth) the object must instead be of one meter or more”, further explained M. Colas, the rating to ” a few kilos”.
According to the Fripon network, a dozen meteorites fall every year in France.
