Why did it take Kepler so many extra years to determine the elliptical orbits of the planets?

1.He presumed Copernicus was correct. 2.He inferred the orbits were circular. 3.Incorrect prior knowledge can delay good reasoning.

Many people would not accept the heliocentric theory because:

1.people had come to accept the idea that the Earth was the center of the universe. 2.the treatise claimed the Earth was not at the center of the universe
