He got a lot of thing correct, however, his biggest problem was that he tried to explain everything.
No I didn't see the program on Venus.
Venus' atmosphere circles the planet at a much faster rate than Venus' rotation. (I forget the exact figures, and don't have time to look them up, but it was something like 5 days for the atmoshere to rotate once versus a couple hundred days for Venus to make one revolution)
Venus rotates backwards relative to the rest of the solar system.
The most interesting tidbit was the information about the surface of the planet. They said that the planet was evenly covered with around only 1,000 craters. They made the point that this was very unusual because it implied that the surface was much "younger" than they expected to find. They pretty much stated as fact that the planet was over 4 billion years old and this meant that the surface had been molten and then solidified in the recent past (the number that was thrown around was 1/2 billion years ago). I'm sure Velikovski would have had a field day with this information. I'm sure he would have taken issue with their conclusions as far as the age of the surface- and the "planet" itself. The scientists reeled off a list of puzzling facts about the planet, but never once mentioned Velikovski or that these puzzling facts just support his theories even more.
