Hi, I am working on an animated short movie about a mission to Venus. I have a few very specific questions to help me get an authentic look. Firstly, would an object in long term orbit around Venus (say a hundred thousand years or so) become coated in dust? If so, what colour? Secondly, what wethering effects due to heat/radiation/other factors would I have to consider (the object is a derelict alien ship, but made of normal metals and alloys familiar to science, not some fancy indestructable material!) Third, after such a long time exposed to such an enviroment, would it be feasable for any trace of organic matter (ie remains of the crew) to be found in the wreckage? thanks in advance!
