🔍 Key Concepts

• Ecliptic as used in celestial navigation and astronomy • The apparent motion of celestial bodies due to Earth’s actual motion • Difference between a diagram or chart and an actual celestial path

💭 Think About

• Ask yourself: in reality, which body is moving around which, and how does that make the other seem to move among the stars? • Consider which choices describe a path in the celestial sphere versus something that is just a type of chart or diagram. • Think about how the Sun seems to move over the course of a year against the background of constellations—what do we call that line?

✅ Before You Answer

• Eliminate any option that is just a type of chart or drawing rather than a specific path in the sky. • Focus on which option correctly uses the phrase "appears to" in the way navigators and astronomers define the ecliptic. • Confirm that the option you choose is tied to the annual motion seen over a year, not daily motion.
