Sabe como é?
Estrelas azuis são as mais quentes, as vermelhas as mais frias. No caso de estrelas, "frio" significa temperaturas da ordem de 2000 ou 3000 K, umas 15 vezes mais quente do que nosso forno de casa. Estrelas azuis têm temperaturas de 20000 K ou mais. O Sol é uma estrela amarela, de temperatura intermediária, próxima a 6000 K. A cor de uma estrela pode ser quantificada pela medida do índice de cor. #estrelas #sabecomoé #querosaber #curiosidades #estronomia
