The English word planet comes from the Greek word Plan.

Stars appear to have fixed positions when compared to other stars, but there are other lights in the night sky that change their positions in relation to the stars and to each other. They move among the stars. The Greek name for these moving lights was plan which means “wanderer.”

We now know that the planets “wander” across the sky because they revolve around the sun.

Chew on that next time you step out for a walk.
