Answer:

Ptolemy, an early Greek astronomer, thought the orbits of the planets were circular.

Explanation:

According to Ptolemy, planets are supposed to move in a small circle called an epicycle that, in turn, moves along a larger circle called deferent. Both circles rotate in a clockwise direction and are more or less parallel to the plane of the Sun's orbit. Although the system was considered geocentric, the movement of the planets was not centered on the Earth but on what is called the eccentric. The orbits of the planets in this system describe epitrocoid curves.
