A Naprendszer a Napb\u00f3l \u00e9s az azt k\u00f6r\u00fclvev\u0151 \u00f6sszes kisebb \u00e9gitestb\u0151l \u00e1ll. A Napon k\u00edv\u00fcl a Naprendszer legnagyobb tagjai a nyolc f\u0151 bolyg\u00f3. A Naphoz legk\u00f6zelebb n\u00e9gy viszonylag kicsi, szikl\u00e1s bolyg\u00f3 tal\u00e1lhat\u00f3: a Merk\u00far, a V\u00e9nusz, a F\u00f6ld \u00e9s a Mars.<\/p>\n<\/div>\n

A Marson t\u00fal ter\u00fcl el az aszteroid\u00f6v \u2013 egy olyan r\u00e9gi\u00f3, amelyet t\u00f6bb milli\u00f3 szikl\u00e1s \u00e9gitest alkot. Ezek a bolyg\u00f3k kialakul\u00e1s\u00e1nak maradv\u00e1nyai, 4,5 milli\u00e1rd \u00e9vvel ezel\u0151ttr\u0151l.<\/p>\n

Az aszteroid\u00f6v t\u00fals\u00f3 oldal\u00e1n tal\u00e1lhat\u00f3k a n\u00e9gy g\u00e1z\u00f3ri\u00e1s \u2013 a Jupiter, a Szaturnusz, az Ur\u00e1nusz \u00e9s a Neptunusz. Ezek a bolyg\u00f3k j\u00f3val nagyobbak a F\u00f6ldn\u00e9l, de m\u00e9ret\u00fckh\u00f6z k\u00e9pest nagyon k\u00f6nny\u0171ek. F\u0151k\u00e9nt hidrog\u00e9nb\u0151l \u00e9s h\u00e9liumb\u00f3l \u00e1llnak.<\/p>\n

Eg\u00e9szen a k\u00f6zelm\u00faltig a legmesszebb fekv\u0151 ismert bolyg\u00f3 egy Pl\u00fat\u00f3 nev\u0171 jeges \u00e9gitest volt. Pl\u00fat\u00f3 azonban a F\u00f6ld Holdj\u00e1hoz k\u00e9pest eleny\u00e9sz\u0151 m\u00e9ret\u0171, \u00e9s sok csillag\u00e1sz \u00fagy v\u00e9li, hogy t\u00fal kicsi ahhoz, hogy igazi bolyg\u00f3nak lehessen nevezni.<\/p>\n

2005-ben a Napt\u00f3l nagyon messze fedeztek fel egy Eris nev\u0171 \u00e9gitestet, amely legal\u00e1bb akkora, mint a Pl\u00fat\u00f3. Az elm\u00falt \u00e9vekben t\u00f6bb mint 1 000, az Erishez hasonl\u00f3 jeges \u00e9gitestet fedeztek fel a Pl\u00fat\u00f3n t\u00fal. Ezeket Kuiper-\u00f6v-objektumoknak nevezik. 2006-ban a Nemzetk\u00f6zi Csillag\u00e1szati Uni\u00f3 \u00fagy d\u00f6nt\u00f6tt, hogy a Pl\u00fat\u00f3t \u00e9s az Erist \u201ct\u00f6rpebolyg\u00f3knak\u201d kell min\u0151s\u00edteni.<\/p>\n

M\u00e9g enn\u00e9l is messzebb tal\u00e1lhat\u00f3k az Oort-felh\u0151 \u00fcst\u00f6k\u00f6sei. Ezek olyan messze vannak, hogy m\u00e9g a legnagyobb t\u00e1vcs\u00f6vekkel sem l\u00e1that\u00f3k. Id\u0151nk\u00e9nt valamelyik \u00fcst\u00f6k\u00f6s p\u00e1ly\u00e1ja megzavarodik, \u00e9s a Nap fel\u00e9 veszi az ir\u00e1nyt. Ekkor v\u00e1lik l\u00e1that\u00f3v\u00e1 az \u00e9jszakai \u00e9gbolton.<\/p>","protected":false},"excerpt":{"rendered":"
