Answer 1

The correct features of Copernicus's model of the solar system are:

1. The stars are fixed to an outer sphere.
2. The Sun is at the center.
3. The planets move in perfect circles.

These features characterize Copernicus's heliocentric model, which proposed that the Sun is at the center of the solar system, with planets orbiting it in circular paths, while the stars are fixed on a distant sphere.
