Darwin

Description
A mid-sized rock planet, Darwin is ironically named, being one of the worst places for life in the galaxy. Its atmosphere is punishing, its temperature boiling, its chemical makeup toxic. Carbon monoxide and methane warp the planet in an unyielding haze, and scans of its surface show only silicates and molten tin. Its daily thermal fluctations lead to hurricane-level vortices, two at each pole, forming "eyes" that can be seen from orbit. Despite all this Darwin is still used by spacers as a drive core discharge point - hydrogen pierces the clouds in the upper atmosphere making for a relatively benign appearance.
