Temperature oko 7800°K, spektralnog tipa A7IV-V. Apsolutne veličine +2,20 je 11 puta sjajnija od Sunca. Stabilna zvijezda u kojoj se energija stvara fuzijom [[vodik]]a u [[helij]]. Altair nije sferičnog oblika, već je spljošten na polovima zbog svoje velike brzine rotacije. Ostale interferometrijske studije s više [[Teleskop|teleskopa]], koji rade u infracrvenom spektru, snimile su i potvrdile ovaj fenomen.<br /> <br /> [[Kategorija: Zvijezde]]<br /> [[Kategorija:Orao (zviježđe)]]</div> WikiSysop
