Poussières d'origine extra-terrestre. De petites particules provenant de météorites pénètrent de façon constante dans l'atmosphère. La masse annuelle d'apport d'essaims périodiques de météores s'élèverait à environ 25 % de celle des météores sporadiques. [...] En comparant à différentes altitudes la concentration des particules d'origine terrestre et celle des particules d'origines extra-terrestre, on a pu avancer qu'à partir de 10 km d'altitude, l'aérosol d'origine extra-terrestre est prédominant. 1, record 1, French, - poussi%C3%A8re%20d%27origine%20extra%2Dterrestre
