Question

which of the celestial bodies listed are observed to undergo retrograde motion at some point in a human lifetime? choose all that apply. saturn the moon mars earth venus mercury the sun jupiter

Explanation:

Retrograde motion is an apparent reversal of the normal motion of a celestial body. Planets (excluding Earth from this perspective as we observe from it) can exhibit retrograde motion as Earth passes them in its orbit. The Moon orbits Earth and doesn't have retrograde motion relative to Earth - based observers in the way planets do. The Sun appears to move across the sky due to Earth's rotation and doesn't have retrograde motion in the relevant sense. Planets like Mercury, Venus, Mars, Jupiter, and Saturn can show retrograde motion as seen from Earth.

Answer:

Saturn, Mars, Mercury, Venus, Jupiter
