Venus spins so slowly that one full rotation takes about 243 Earth days, yet it circles the Sun in just 225. That's not its only quirk: it also spins backward compared with almost every other planet. Stand on its surface (if you could survive the heat) and you'd watch the Sun rise in the west.
A large share of Earth's water molecules formed in the interstellar cloud that existed before the Sun was even born, more than 4.6 billion years ago. You are literally drinking a cosmic fossil.
By day, the Martian sky looks butterscotch because of fine dust hanging in the air. But at dusk, those same grains scatter blue light forward, creating a bluish glow around the Sun. Rovers have photographed these blue sunsets: the exact reverse of what we see on Earth.
