The Aphelion of Comet Churyumov–Gerasimenko is about 5.6829 AU. It has a orbital period of 6.44 years. If it stays on the comet for the entire period of its orbit, can it be usable when it is in the same position after 6.44 years?
I am guessing the wear and tear to be mainly from radiation and temperature variations. Are there any other dangers?
