P\u00e4ikeses\u00fcsteem on t\u00e4is planeetide tekkimisel j\u00e4rele j\u00e4\u00e4nud ainet. Kosmoses ringlevaid v\u00e4ikeseid kivikilde nimetatakse meteoroidideks. Kui need sisenevad planeedi atmosf\u00e4\u00e4ri ja p\u00f5levad \u00e4ra, nimetatakse neid meteoriteks. M\u00f5nikord j\u00e4\u00e4vad suuremad kivikillud piisavalt kaua terveks, et p\u00f5rkuda planeedi pinnaga. Maa pinnal leiduvaid kosmosekive nimetatakse meteoriitideks.<\/p>\n<\/div>\n

Meteoorid (mida sageli nimetatakse \u201clangevateks t\u00e4htedeks\u201d) on v\u00e4ga tavaline n\u00e4htus. Iga\u00fcks, kes vaatab selget \u00f6\u00f6taevast, n\u00e4eb l\u00f5puks neid l\u00fchikesi valgusj\u00e4lgi. Meteoorid tekivad siis, kui meteoriidid sisenevad \u00fclemisse atmosf\u00e4\u00e4ri kiirusega umbes 15 km\/s! Meteooride valgusj\u00e4ljed kestavad tavaliselt v\u00e4hem kui sekundi. H\u00f5redas \u00f5hus umbes 100 km k\u00f5rgusel tekkiv h\u00f5\u00f5rdumine paneb meteoriidid kuumenemise tagaj\u00e4rjel helendama ja seej\u00e4rel h\u00e4vib.<\/p>\n

Meteoore v\u00f5ib n\u00e4ha igal ajal, kuid parim aeg nende vaatlemiseks on perioodiliste meteoorivihmade ajal. Sellised vihmad ilmuvad igal aastal umbes samadel kuup\u00e4evadel, kui Maa l\u00e4bib m\u00f6\u00f6duva komeedi poolt maha j\u00e4etud tolmujoa.<\/p>\n

Peamisi meteoorivihme on umbes 20, kuigi vaid m\u00f5ned neist tekitavad kuni 50 meteoori minutis. Aeg-ajalt t\u00e4itub taevas langevate t\u00e4htedega. K\u00f5ige kuulsamad \u201cmeteooritormid\u201d on seotud Leonidide meteoorivihmaga, mis toimub igal aastal 14.\u201320. novembril. See meteoorivihm on minevikus olnud nii aktiivne, et meenutas langevat lund!<\/p>\n

M\u00f5ned meteoorid on liiga n\u00f5rgad, et neid isegi \u00f6\u00f6sel n\u00e4ha, kuid neid on v\u00f5imalik radariga tuvastada. Ka teistel planeetidel esineb meteoorivihme. Marsil p\u00f5levad meteoriidid \u00fcldjuhul \u00f5hukeses atmosf\u00e4\u00e4ris \u00e4ra, tekitades meteoore. Kuul aga \u00f5hku pole, mist\u00f5ttu meteoriidid p\u00f5rkuvad maapinnale ja plahvatavad, ilma et \u00e4ra p\u00f5leksid.<\/p>","protected":false},"excerpt":{"rendered":"
