I have a weird question... <br /><br />I wonder how the world knew Uranus and Neptune before Voyager 2 arrived? What where the best pictures made so far at that point? I assume nothing spectacular... I have found a pdf-file somewhere, with a huge article of 1972, and at that point they knew nothing really about the colours, or how the 'discs' looked like. At that point, Pluto still had no moon and was thought to be about 6,900 km diameter!<br /><br />So just out of curiosity, what was the 'conception' of these huge planets about that point? I have found some great PDF files with information of the planets before the arrivals of the Mariners, Galileo and Cassini. Does anyone knows where to find something similar of the arrivals of Voyager at Neptune and Uranus? <br /><br />I really like reading such 'historic' documents.
