Question 1 of 27070

Which term defines the small circle of the celestial sphere parallel to the celestial equator, and transcribed by the daily motion of the body?

🔍 Key Concepts

• Celestial equator and how circles parallel to it are named • Difference between a circle through the poles (great circle) and a small circle on the celestial sphere • How a star’s apparent daily motion traces a path on the celestial sphere

💭 Think About

• Ask yourself: when the Earth rotates, what kind of path does a star near the celestial equator appear to follow across the sky? Is that path a great circle or a small circle? • Which of the options refers to something that is parallel to the celestial equator, not passing through the celestial poles or through the zenith? • Match each term: which one is associated with declination, which with hour angle, which with altitude, and which with vertical circles?

✅ Before You Answer

• Identify which option names a circle that is explicitly parallel to the celestial equator • Eliminate any option that describes a circle that passes through the poles or through the observer’s zenith • Verify from your notes: declination is measured north–south from the celestial equator along a certain kind of circle—does that relate to a parallel or a great circle?
