It is very cold, but otherwise comfortable. You breathe deeply. Although there is no oxygen, the air pressure is quite tolerable and seems almost Earth-like (because it is mostly nitrogen).
 
  Your vista includes the breathtaking sights of an ocean of liquid methane and methane-snow-capped mountains (although the atmosphere is very smoggy, and the visibility is limited). Your solar day is about 16 Earth days long. A large, ringed object seems to hang in your sky, never rising or setting; however, it does go through phases from new to full and back to new again with the same 16-day period as the rising and setting of the Sun.
