CHE SIGNIFICA METEOROID IN INGLESE
meteoroide
Un meteoroide è un piccolo corpo roccioso o metallico che attraversa lo spazio. I meteoridi sono notevolmente più piccoli degli asteroidi e sono di dimensioni variabili da piccoli chicchi a oggetti di larghezza di 1 metro. Oggetti più piccoli di questo sono classificati come micrometeoridi o polveri spaziali. La maggior parte sono frammenti di comete o asteroidi, mentre altri sono detriti di impatto di collisione espulsi da corpi come la Luna o Marte. Quando un tale oggetto entra nell'atmosfera terrestre a velocità tipicamente superiori ai 20 km / s, il riscaldamento aerodinamico produce una striscia di luce, sia dall'oggetto incandescente che dal tracciato di particelle luminose che lascia la sua scia. Questo fenomeno è chiamato meteora, o colloquialmente una "stella di tiro" o "stella cadente". Una serie di tanti meteor che appaiono secondi o minuti separati, e che appaiono originati dallo stesso punto fisso nel cielo, si chiama una doccia meteora. Gli oggetti in ingresso più grandi di diversi metri possono esplodere nell'aria. Se un meteoroide, una cometa o un asteroide o un pezzo di esso sopporta l'ablazione dalla sua entrata atmosferica e colpisce con il suolo, allora si chiama meteorite.
definizione di meteoroid nel dizionario inglese
La definizione di meteoroide nel dizionario è uno dei piccoli corpi celesti che si pensa possano orbitare intorno al sole, probabilmente come i resti delle comete. Quando entrano nell'atmosfera terrestre, diventano visibili come meteore.
