A Nap egy csillag. A legt\u00f6bb csillaghoz hasonl\u00f3an a Nap is egy rendk\u00edv\u00fcl forr\u00f3 g\u00e1zg\u00f6mb, amely hatalmas mennyis\u00e9g\u0171 f\u00e9nyt, h\u0151t \u00e9s egy\u00e9b sug\u00e1rz\u00e1st bocs\u00e1t ki. Ezt a sug\u00e1rz\u00e1st a magj\u00e1ban zajl\u00f3 nukle\u00e1ris reakci\u00f3k hozz\u00e1k l\u00e9tre. Ez olyan, mintha m\u00e1sodpercenk\u00e9nt t\u00f6bb milli\u00f3 hidrog\u00e9nbomba robbanna fel.<\/p>\n<\/div>\n

Sz\u00e1mos k\u00fcl\u00f6nb\u00f6z\u0151 csillagt\u00edpus l\u00e9tezik. A v\u00f6r\u00f6s csillagok a leghidegebbek, felsz\u00edni h\u0151m\u00e9rs\u00e9klet\u00fck k\u00f6r\u00fclbel\u00fcl 2500 Celsius-fok. A k\u00e9kesfeh\u00e9r csillagok a legforr\u00f3bbak, h\u0151m\u00e9rs\u00e9klet\u00fck el\u00e9ri a forr\u00f3
40 000 fok. A Naphoz hasonl\u00f3 s\u00e1rga csillagok a kett\u0151 k\u00f6z\u00f6tt helyezkednek el, felsz\u00edni h\u0151m\u00e9rs\u00e9klet\u00fck k\u00f6r\u00fclbel\u00fcl 5500 fok.<\/p>\n

A csillagok m\u00e9rete nagyon v\u00e1ltoz\u00f3. A Nap k\u00f6zepes m\u00e9ret\u0171. Hidrog\u00e9n-\u00fczemanyag\u00e1t meglehet\u0151sen lassan \u00e9geti el, \u00edgy 10 milli\u00e1rd \u00e9vig k\u00e9pes ragyogni. Vannak csillagok, amelyek sokkal nagyobbak \u00e9s forr\u00f3bbak, mint a Nap. Az Antares nev\u0171 v\u00f6r\u00f6s szuper\u00f3ri\u00e1s 800-szor nagyobb, mint a Nap. Ha a Naprendszer\u00fcnk k\u00f6zep\u00e9n lenne, elnyeln\u00e9 az \u00f6sszes bels\u0151 bolyg\u00f3t, bele\u00e9rtve a F\u00f6ldet is. Ak\u00e1rcsak a nagy fogyaszt\u00e1s\u00fa aut\u00f3k, ezek a szuper\u00f3ri\u00e1sok is nagyon gyorsan felhaszn\u00e1lj\u00e1k az \u00f6sszes hidrog\u00e9n- \u00e9s h\u00e9lium-tartal\u00e9kukat. K\u00f6r\u00fclbel\u00fcl 500 milli\u00f3 \u00e9v m\u00falva szupern\u00f3va-robban\u00e1sban halnak meg.<\/p>\n

A leghidegebb, leglassabban \u00e9g\u0151 csillagok a v\u00f6r\u00f6s t\u00f6rp\u00e9k. Ezek t\u00f6bb mint 10 billi\u00f3 (10 000 milli\u00e1rd) \u00e9vig is fennmaradhatnak. M\u00e9g hidegebbek \u00e9s kisebbek a barna t\u00f6rp\u00e9k. Ezek \u2018sikertelen csillagok\u2019. Olyan hidegek \u2013 n\u00e9ha a felsz\u00edn\u00fck\u00f6n csup\u00e1n n\u00e9h\u00e1ny sz\u00e1z fok \u2013 hogy magjukban soha nem indul be az \u00e9g\u00e9s.<\/p>","protected":false},"excerpt":{"rendered":"
