What kind of experience will it be when you are on Pluto and on Sedna and they are at their farthest point from the Sun (aphelion) Pluto about 90 AU then and Sedna an unimaginable 900 AU. How bright will the Sun shine at Plutos farthest distance to the Sun at 90 AU ,and what about its brightness when you are on Sedna at its aphelion at 900! AU? When we send landers to Pluto and Sedna in the future ,do they need (extra) lights because of the dimness of the Sun? Can somebody explain these things?
