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 placed the Sun at the center of the universe, which went against the geocentric (Earth - centered) view that was supported by religious teachings (the Catholic Church at that time). The Church had a significant influence, and challenging its views (even scientific ones) was met with resistance. The other options are incorrect: having the moon orbit Earth is a correct aspect of the heliocentric model; Copernicus' model could explain retrograde motion (by the relative positions and speeds of planets); and the concept of eight planets in the solar system as we know it today is a later - developed idea (Uranus was discovered in 1781, Neptune in 1846, and the demotion of Pluto occurred much later).

Answer:

The model was against religious teachings.
