The Professor was asking the class what those 7 ancients stars were. Sander tried to remember whether he had read something about them somewhere. Then he heard one of the other students share an answer and that's when everything became familiar.

He raised his hand and gave his own answer, "Professor, unlike most stars that moved in a fixed formation, around the Earth, the seven wandering stars, or in this case, celestial bodies moved through the fixed stars in a wide band, called the zodiac. These bodies were actually the planets, Mercury, Venus, Mars, Jupiter, Saturn and of course the Sun and the Moon." Sander concluded his answer.
