People, please don't start this debate again; it's been talked to death elsewhere on this forum, and my migraine is finally almost gone...
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

QUOTE (nprev @ Oct 7 2007, 08:25 PM)  People, please don't start this debate again; it's been talked to death elsewhere on this forum, and my migraine is finally almost gone... When speaking of the 1950s and 60s, many people assume Pluto had a diameter of ~6,000 km. This is because they assumed it would have a very low albedo. In other words, they thought it was a larger, less reflected world. Some of this came from guesses that proved wrong, and the rest came from the the fact that they were observing the combination of Pluto and Charon and assuming it to be entirely Pluto. Ley probably put it with the terrestrials because it is solid, unlike the four gas giants. Even then, that was a stretch, but I can at least see the line of reasoning. -------------------- |
