Uh, I think Mercury might be just a teensy weensey warm for human habitation.

""From the night, Mercury's surface temperature changes 1,130 °F (630 °C), more than any other planet or moon in the solar system. Just before sunrise on a typical day on Mercury the temperature is -300 °F (-180 °C). By midmorning the temperature rises to 80 °F (27 °C). At noontime, 22 Earth days since the sun rise, it has climbed to 765 °F (407 °C). In the early afternoon the temperature reaches a high of 800 °F (427 °C), hot enough to melt zinc and tin."

The key piece of data is:

noontime, 22 Earth days since the sun rise

It's like the old joke -- we'd go at night. ;')
