A Nap a hozz\u00e1nk legk\u00f6zelebb l\u00e9v\u0151 csillag. A Nap f\u00e9nyt \u00e9s h\u0151t biztos\u00edt sz\u00e1munkra. Ugyanakkor vesz\u00e9lyes ultraibolya sug\u00e1rz\u00e1st is bocs\u00e1t ki, amely le\u00e9g\u00e9st okoz, \u00e9s r\u00e1kot is kiv\u00e1lthat. A Nap n\u00e9lk\u00fcl nem lenne nappali f\u00e9ny, \u00e9s bolyg\u00f3nk egyszer\u0171en csak egy s\u00f6t\u00e9t, fagyos vil\u00e1g lenne, foly\u00e9kony v\u00edzzel teli \u00f3ce\u00e1nok \u00e9s \u00e9let n\u00e9lk\u00fcl.<\/p>\n<\/div>\n

Ez a hatalmas, rendk\u00edv\u00fcl forr\u00f3 g\u00e1zg\u00f6mb \u00e1tm\u00e9r\u0151je 1,4 milli\u00f3 kilom\u00e9ter, ami 109 egym\u00e1s mell\u00e9 helyezett F\u00f6ldnek felel meg. 2 milli\u00f3 billi\u00f3 billi\u00f3 kilogrammos t\u00f6meg\u00e9vel annyit nyom, mint 330 000 F\u00f6ld. K\u00f6r\u00fclbel\u00fcl 1 300 000 F\u00f6ld f\u00e9rne el a Nap belsej\u00e9ben!<\/p>\n

A F\u00f6ldr\u0151l n\u00e9zve \u00fagy t\u0171nik, hogy a Nap nappal az \u00e9gen halad \u00e1t, \u00e9jszaka pedig elt\u0171nik. Ez az\u00e9rt van, mert a F\u00f6ld kelet fel\u00e9 forog. A F\u00f6ld a saj\u00e1t tengelye k\u00f6r\u00fcl forog, amely egy k\u00e9pzeletbeli vonal, amely a F\u00f6ld k\u00f6zep\u00e9n halad \u00e1t az \u00c9szaki- \u00e9s a D\u00e9li-sark k\u00f6z\u00f6tt. Ez azt jelenti, hogy sz\u00e1munkra, akik a forg\u00f3 F\u00f6ld\u00f6n \u00e9l\u00fcnk, \u00fagy t\u0171nik, hogy a Nap reggel keleten kel fel, majd d\u00e9l fel\u00e9 egyre magasabbra emelkedik az \u00e9gen. D\u00e9lut\u00e1n a Nap egyre alacsonyabbra s\u00fcllyed az \u00e9gen, miel\u0151tt nyugaton lenyugszik.<\/p>\n

B\u00e1r napkeltekor vagy napnyugtakor kicsinek t\u0171nik, ez csup\u00e1n annak k\u00f6sz\u00f6nhet\u0151, hogy a Nap k\u00f6r\u00fclbel\u00fcl 150 milli\u00f3 km-re van t\u0151l\u00fcnk. Ezen a t\u00e1vols\u00e1gon a napf\u00e9nynek k\u00f6r\u00fclbel\u00fcl 8 percbe telik, mire eljut hozz\u00e1nk \u2013 m\u00e9g akkor is, ha k\u00f6r\u00fclbel\u00fcl 300 000 km\/s sebess\u00e9ggel halad. Ez azt jelenti, hogy a Naplement\u00e9t nyolc perccel azut\u00e1n l\u00e1tjuk, hogy az esem\u00e9ny val\u00f3j\u00e1ban megt\u00f6rt\u00e9nt!<\/p>","protected":false},"excerpt":{"rendered":"
