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.
Selvom den er Jord-lignende, og  selvom der i sin tidlige historie meget vel kan have Jord-lignende liv, så bukkede den under for en løbsk drivhus-virkning der er ca 400 °C på overfladen, p.gr.a. en voldsom kuldioxid.
