Mercury

Mercury is the closest planet to the Sun, and therefore follows the Sun in the sky, and can be seen after sunset or before dawn. Because of its proximity to the Sun, it is tidally locked. Mercury's axis has the smallest tilt of any planet in the solar system. It also resembles the Moon in some way. They're both barren, and they both have really epic temperature ranges. The daylight would fry you and the night side would freeze you. Now that I think of it, Mercury is much worse than I thought.
