🔍 Key Concepts

• Celestial equator system as the sky-version of Earth’s latitude/longitude grid • On Earth: meridians run pole-to-pole and measure longitude • In the sky: identify which circles run through the celestial poles and are used with right ascension

💭 Think About

• First match the analogy: declination on the celestial sphere corresponds to which Earth coordinate, latitude or longitude? • Once you know that, ask: are meridians more like lines of equal latitude or lines of equal longitude? • Look at each choice and ask: which one forms great circles passing through both celestial poles, similar to meridians passing through Earth’s poles?

✅ Before You Answer

• Be sure which option is used together with right ascension in the celestial equator system • Confirm which option forms great circles through the celestial poles, not horizontal or local circles • Eliminate any option that better matches parallels of latitude rather than meridians of longitude
