Urmărește-ne pe DiscoverCea mai bună perioadă de urmărire este după miezul nopţii până dimineaţa. Predicţiile spun că se vor vedea maximum 100 de meteori pe oră, în condiţii ideale. În timpul maximului perseidelor se poate vedea cam un meteor pe minut.
Fenomenul de stea căzătoare este arhicunoscut. Dâra luminoasă de pe cer este lăsată de o particulă sub 1 mm diametru ce arde în atmosfera Pământului, la frecarea cu aerul. Pentru o fracţiune de secundă vedem acest fenomen, denumit de astronomi meteor.
