is the apparent retrograde motion of the planets consistent or inconsistent with belief in an earth-centered system? explain

The answer is: 1.- Eclipses can occur outside the Earth-Moon system. 2.- The reason we see that a planet describes a retrograde trajectory in our sky is because of the way it moves with respect to the earth.

Explanation:

1.- The eclipse is a phenomenon in which the light coming from a celestial body is blocked by another, normally called an eclipsing body, there are eclipses of the Sun and the Moon, which only occur when the Sun and Moon align with Earth in a certain way. This happens during some new moons and full moons.

However, eclipses outside the Earth-Moon system can also occur.

2.- The word planet is applied to the stars that modify their positions with respect to the fixed stars.

The Sun and the Moon move in a more or less regular way, throughout space, always moving from west to east, but there are five planets that travel in a more irregular way.  

Thus these five move along the space from west to east, although this movement is interrupted for brief intervals by a retrograde movement from east to west. The reason we see that a planet describes a retrograde path in our sky is because of the way it moves with respect to the earth.
