Sistemul Solar este plin de resturi r\u0103mase \u00een urma form\u0103rii planetelor. Buc\u0103\u021bile mici de roc\u0103 care c\u0103l\u0103toresc prin spa\u021biu sunt cunoscute sub numele de meteoroizi. Dac\u0103 intr\u0103 \u00een atmosfera unei planete \u0219i se ard, ele sunt atunci observate ca meteori. Uneori, buc\u0103\u021bile mai mari de roc\u0103 supravie\u021buiesc suficient de mult pentru a se pr\u0103bu\u0219i pe suprafa\u021ba unei planete. Rocile spa\u021biale de pe suprafa\u021ba P\u0103m\u00e2ntului sunt cunoscute sub numele de meteori\u021bi.<\/p>\n<\/div>\n

Meteorii (denumi\u021bi adesea \u201cstele c\u0103z\u0103toare\u201d) sunt un fenomen foarte frecvent. Oricine prive\u0219te cerul senin \u00een timpul nop\u021bii va vedea, mai devreme sau mai t\u00e2rziu, aceste urme scurte de lumin\u0103. Meteorii sunt genera\u021bi de meteori\u021bi care p\u0103trund \u00een atmosfera superioar\u0103 cu viteze de aproximativ 15 km\/s! Urmele l\u0103sate de meteori dureaz\u0103, de obicei, mai pu\u021bin de o secund\u0103. Fric\u021biunea cu aerul rarefiat de la o altitudine de aproximativ 100 km face ca meteori\u021bii s\u0103 str\u0103luceasc\u0103 pe m\u0103sur\u0103 ce se \u00eenc\u0103lzesc \u0219i apoi se distrug.<\/p>\n

Meteorii pot fi observa\u021bi \u00een orice moment, dar cel mai bun moment pentru a-i admira este \u00een timpul ploilor periodice de meteori. Aceste ploi apar \u00een fiecare an cam \u00een acelea\u0219i perioade, c\u00e2nd P\u0103m\u00e2ntul traverseaz\u0103 un nor de praf l\u0103sat \u00een urm\u0103 de o comet\u0103 care trece pe l\u00e2ng\u0103 el.<\/p>\n

Exist\u0103 aproximativ 20 de roiuri principale, de\u0219i doar c\u00e2teva dintre ele produc p\u00e2n\u0103 la 50 de meteori pe minut. Uneori, cerul se umple de stele c\u0103z\u0103toare. Cele mai faimoase \u201cfurtuni de meteori\u201d sunt asociate cu ploaia de meteori Leonide, care are loc \u00een fiecare an \u00eentre 14 \u0219i 20 noiembrie. \u00cen trecut, aceast\u0103 ploaie a fost at\u00e2t de intens\u0103 \u00eenc\u00e2t sem\u0103na cu ninsoarea!<\/p>\n

Unii meteori sunt prea slabi pentru a fi v\u0103zu\u021bi, chiar \u0219i noaptea, dar pot fi detecta\u021bi cu ajutorul radarului. \u0218i alte planete au ploi de meteori. Pe Marte, meteori\u021bii se consum\u0103, \u00een general, \u00een atmosfera rarefiat\u0103, d\u00e2nd na\u0219tere la meteori. Pe Lun\u0103, \u00eens\u0103, nu exist\u0103 aer, a\u0219a c\u0103 meteori\u021bii lovesc solul \u0219i explodeaz\u0103 f\u0103r\u0103 s\u0103 se consume.<\/p>","protected":false},"excerpt":{"rendered":"
