Chapter 2 Cosmology - the study of the workings of the universe on the largest scales The Solar System - the Sun, Earth, Moon, and the planet known at that time (of the Greeks) Direct/Prograde Motion - the planet’s eastern motion Retrograde Motion - the planet’s backward (westward) motion/loops Inferior “Lower” Planets - the planets whose orbits that lie between Earth and the Sun.
