Lost in the Solar System: You have been abducted by an alien being. After performing experiments on you, the alien gives you a “life-support belt”, allowing you to survive in any environment, and dumps you somewhere in the solar system. Each question below gives a brief description of a place where you were left by the alien. Identify your location. Be as specific as possible. Include a brief explanation for your answer. You find yourself on a silent airless world! The lack of an atmosphere means that you must be very careful not to look at the Sun so that you will not be blinded by its ultraviolet and X-ray radiation. However, you are able to determine that the Sun has about the same angular size that you are used to on Earth. Although this world is clearly lifeless, you are surprised to find footprints and car tracks etched in the powdery surface.

You’ve been dropped at the edge of a cliff, looking down for what seems to be miles! There’s only one way to go from here: up! But it’s going to be quite a climb, requiring all of your mountaineering skills. The atmosphere is very thin even at the mean surface level of this place. No matter, though, as you could not breathe this atmosphere anyway because it is mostly carbon dioxide and contains no oxygen. You climb and climb. This mountain must be three times the height of Mt. Everest and much broader at its base. There are clouds around you, and you can find water ice as well. When you try to melt some ice, however, it does not turn to liquid but sublimes to gas.
