Uranus

The oddest thing about Uranus is that the planet, its rings, and its moons "roll" around the Sun on an axis tilted by more than 90 degrees. The other planets orbit more like spinning tops with their axis pointed more straight up and down. This planet's surface is hidden from our view by a thick layer of cold smog.
