To the ancients the earth was the centre of the universe and the sun and other stars appeared to rotate around it. In contrast, the five planets that are visible to the naked eye seemed to 'wander' about the sky and were assigned Greek names amounting to wandering stars which have been corrupted to 'planet' in English.
