Answer

Answer:

The planets spun in epicycles.

Brief Explanation:

El modelo de Ptolomeo usaba epícyclos para explicar la retrogradación aparente de los planetas. Las epíclicas son pequeñas órbitas circulares en las que los planetas se movían mientras giraban en órbitas más grandes alrededor de la Tierra. Esta idea ayudaba a explicar por qué los planetas parecían moverse hacia atrás en el cielo en ciertos momentos.
