QUOTE I remember seeing an early-80s artistic view of Pluto and Charon where the latter was depicted as non-spherical and asteroid-like. anyone else remembers it? from the 80's ???? i might be wrong but i thought that even when i first saw or read sagsn's "cosmos" ( sept. 1980 ) that the radius was known at least that it was bigger that 1000Km in diameter Charon ? was discovered in 1978 so by 1980 ? a mass ( very ruff ) and orbit and range for the diameter should have been known for both Pluto and Charon now for P2,P3,P4,and P5 these are small -- Artists concept -- |
