The three correct features of Copernicus's model of the solar system are:
1. **The sun is at the center.**
2. **The stars are fixed to an outer space.**
3. **The outer planets move in epicycles.**
Note: While Copernicus advanced the idea that planets move around the sun, he still retained some aspects of the Ptolemaic system, such as the use of epicycles to explain planetary motion and the notion that orbits were circular rather than elliptical.
