The correct answer is option 4.
Ancient Greek philosophers tried to explain the solar system. One of them was Ptolemy an ancient astronomer who gave the "geocentric model" of the solar system considering Earth as the center but later Copernicus in 1543 proposed the heliocentric model of the solar system with Sun at the center.
Both the models share central principles such as:
1. Speed of astronomical bodies- sun, moon and stars are constant.
2. The astronomical bodies- sun, moon and stars move in circular orbits.
Thus, option 4 is the correct answer.
