Which of these things did the Voyager spacecraft discover about Enceladus in the early 1980s, indicating that it is somewhat unusual among planetary bodies in our solar system? Check the TWO items that apply. a It has a thick atmosphere, made mostly of nitrogen. b It has the darkest, least reflective surface of all the known planetary bodies. c It is the brightest (i.e. most reflective) object in the solar system. d The entire surface is more heavily-cratered than any other body in our solar system. e Its surface is very smooth in some places.
