You are walking around on a solid surface; the surface gravity is comfortable, but it is "hot as hell." It feels as if your eyeballs are being squeezed, and your insides are queasy (due to the high pressure—almost like being deep in the ocean)
Your life-support belt is corroding. The Sun, barely visible through the haze, is near your meridian; you hope for nightfall (unaware that it would provide no substantial relief), but you already have been stuck on this planet for 72 hours, and the Sun seems not to have moved through the sky (and, if it moved at all, it moved eastward from the meridian).
You are on Venus, of course! The slow, backward motion of the Sun is the result of Venus's slow, retrograde rotation.
