according to ptolemy's model of the movement of celestial bodies,?

Question

a. the earth rotates around the sun
b. the sun is the center of the universe
c. the earth rotates around the moon
d. planets orbit in circular paths around the earth

Answer 1

The correct answer is None of the Above.

A planet's path around the earth is not circular around the earth in Ptolemy's system. Rather, a planet's path is circular around an epicycle, which is in turn circular around the earth. This is the system's explanation for retrograde motion.

Answer 2

The answer is d.

Ptolemy's model was the one followed during the Middle Dark Ages, when religious superstition kept science and advancement to a very primitive level.

Answer 3

d. This theory was not disproved until Kepler, almost 2000 years later.
