"Although planets resemble stars as one observes the night sky, the planets change position from night to night in relation to the stars. Like the sun, the planets appear to rise in the east and set in the west. When a planet travels westward in relation to the stars, its motion is called retrograde." Based on the preceding paragraph, what does the word retrograde mean?

Respuesta :

It is the motion of it going westward

Answer:

Based on the preceding paragraph, the word retrograde means that the planet moves westward in relation to the stars.

Explanation:

A retrograde movement in astronomy is when the celestial body goes westward in relation to the stars. This means that the orbit of this celestial body runs counter to the direction of the spin of that body which it orbits. It is mention in the paragraph right before the use of the word retrograde, in fact, the sentence with the word retrograde is paraphrasing its meaning.
