Even though it's Earth-like, and even though early in its history it may very well have harbored Earth-like life, it soon succumbed to runaway greenhouse — that's an 800 degrees [Fahrenheit] surface — because of rampant carbon dioxide.
A pesar de ser semejante a la Tierra, e incluso al principio de su historia pudo haber albergado vida semejante a la de la Tierra, pronto sucumbió a un efecto invernadero galopante... una superficie de 800 grados centígrados... a causa del aumento del dióxido de carbono.
