Question

why was copernicuss heliocentric model not believed until galileo and kepler provided more evidence?
the model had the moon orbiting earth.
the model was against religious teachings
the model could not explain retrograde motion.
the model did not include all eight planets in the solar system.

Explanation:

Copernicus' heliocentric model challenged the geocentric view (Earth - centered) which was supported by religious teachings at the time. The Church had a significant influence, and ideas that contradicted its teachings were met with resistance. The moon orbiting Earth is a correct aspect (even in heliocentric model, as Earth - moon system orbits Sun). Retrograde motion was explained (though Copernicus' explanation was more complex than later ones). At the time, the concept of eight planets as we know now wasn't the standard (Uranus, Neptune were discovered later).

Answer:

The model was against religious teachings.
