Venus is a gorgeous naked-eye planet, hanging like a diamond in the twilight — but it’s beauty is best looked at from afar. Even though Mercury is closer to the sun, Venus is the hottest planet in the solar system, due to a runaway greenhouse effect, and has the most volcanic activity in the solar system. Its north and south poles were flipped, causing it to rotate backwards and making for very strange days on this beautiful but inhospitable world.

S.A. B says:

i dont think it was a runaway greenhouse that made venus like that: it was always in a position to evaporate its liquids. its probably always had an atmosphere like that.

Thomas Chase says:

It's all that red and pink floral wall paper and upholstery on the furniture that makes me cringe whenever I venture to close.
