When I was 5 I used to believe that the planet 'Pluto' was actually the disney character who had been banished from the planet because he had been really naughty, and sent into orbit. I believed that until I was about 8, when I had a Science lesson on the Solar System, when I then learnt that it was a planet of it's own. I felt really stupid when my teacher told the class that it was the furthest planet, and not a disney character. I wasn't the only one who felt foolish., though. Plenty of people mady 'daft' mistakes that lesson.
