if you do like to program just get a telescope any will do (the better the more accurate the results) and chart the orbital paths of the planets for a couple of years and then show that the earth is not rotating, the planets rotate about us, and the distances are not what we thought. If you do not want to take the time to do that then just get the observastions of others and use those to calculate the above, I would suggest the observations made by Brahe
