Astronomy - Why do planets sometimes go backwards? 2-4 Sentence Response

Sometimes, as seen in Earth’s sky, the planets seem to move backwards!

Typically, the planets shift slightly eastward from night to night, drifting slowly against the backdrop of stars. From time to time, however, they change direction. For a few months, they’ll head west before turning back around and resuming their easterly course. Their westward motion is called retrograde motion by astronomers. Though it baffled ancient stargazers, we know now that retrograde motion is an illusion caused by the motion of Earth and these planets around the sun.
