Nagu enamik t\u00e4hti, on ka P\u00e4ike v\u00e4ga kuum gaasipall, mis kiirgab tohutuid koguseid valgust, soojust ja muud kiirgust. See kiirgus tekib tuumas toimuvate tuumareaktsioonide tulemusel. See on nagu miljonid vesinikpommid, mis plahvatavad iga sekundi j\u00e4rel.<\/p>\n<\/div>\n<p>T\u00e4hti on palju erinevaid liike. Punased t\u00e4hed on k\u00f5ige jahedamad, nende pinnatemperatuur on umbes 2500 kraadi Celsiuse j\u00e4rgi. Sinivalged t\u00e4hed on k\u00f5ige kuumemad, nende temperatuur ulatub kuni<br \/>40 000 kraadi. P\u00e4ikesega sarnased kollased t\u00e4hed asuvad nende vahel, nende pinnatemperatuur on umbes 5500 kraadi.<\/p>\n<p>T\u00e4hed on erineva suurusega. P\u00e4ike on keskmise suurusega. Ta p\u00f5letab oma vesinikuk\u00fctust \u00fcsna aeglaselt, mist\u00f5ttu suudab ta s\u00e4rada 10 miljardit aastat. M\u00f5ned t\u00e4hed on P\u00e4ikesest palju suuremad ja kuumemad. Punane hiidt\u00e4ht Antares on 800 korda laiem kui P\u00e4ike. Kui see asuks meie P\u00e4ikeses\u00fcsteemi keskel, neelaks see endasse k\u00f5ik sisemised planeedid, sealhulgas Maa. Nagu suure k\u00fctusekuluga autod, kulutavad need hiidt\u00e4hed kogu oma vesiniku- ja heeliumik\u00fctuse v\u00e4ga kiiresti \u00e4ra. Umbes 500 miljoni aasta p\u00e4rast surevad nad supernoova plahvatuses.<\/p>\n<p>K\u00f5ige jahedamad ja aeglasemalt p\u00f5levad t\u00e4hed on punased k\u00e4\u00e4bused. Need v\u00f5ivad p\u00fcsida \u00fcle 10 triljoni (10 000 miljardi) aasta. Veel jahedamad ja v\u00e4iksemad on pruunid k\u00e4\u00e4bused. Need on \u2018eba\u00f5nnestunud t\u00e4hed\u2019. Nad on nii jahedad \u2013 m\u00f5nikord on nende pinnatemperatuur vaid m\u00f5nisada kraadi \u2013, et nende tuumareaktorid ei hakka kunagi p\u00f5lema.<\/p>","protected":false},"excerpt":{"rendered":"<p>The Sun is a star.
