Nobody will answer these for you straight away, why don't you list your answers with reasons as to why you think that it's right, and I'll be happy to look them over and tell you where you are wrong.

I have to get back to work, but I will check your answers in 3 hours time. Unless someone else does it in the meantime :)

I count 6 wrong answers. Here are some clues:

Copernicus was the first to argue that the earth and the other planets orbit the sun. Prior to that, people thought that the earth was the center of everything. He came long after Aristotle and Ptolemy.

Kepler was the first to realize that the planets move in elliptical orbits, not circular. He came after Copernicus.

Galileo actually did observe the rings of Saturn. He drew them up in his notebook looking like big ears.

Hope this helps.
