Strangely, the article omits a reference to the preferred model of the time, namely the Tychonic system [1]. In the Tychonic system, all the planets revolve around the Sun, but the Sun and moon revolve around the Earth. It was seen to be a very tidy theory that took advantage of the best aspects of the Copernican theory, but resolved the problem of the lack of observed parallax.

- dumbmatter 10y agoThe article does mention it: Brahe had theorised that all planets circled the Sun, while it circled Earth. Locher noted that Brahe might be right, but what was clear was that the telescope supported Ptolemy.
