The Ptolmaic system forecast the positions of planets more accurately
than Copernicus', because the latter was constrained to use circular
orbits centred on the sun. Only when Kepler realised that the orbits
were ellipses, and that the planets slowed down and speeded up as they
went round, could the heliocentric system match the geocentric one.

Thanks. In the previous couple of posts, please read "Kepler" for
"Copernicus".

That's a relief. I thought you were espousing the perfect spheres as a newfangled scientific theory.
