🔍 Key Concepts

• Celestial equator system as the sky-analogue of Earth’s latitude/longitude grid • How we measure positions north or south of the celestial equator • Difference between coordinates measured east–west along the equator vs north–south from the equator

💭 Think About

• On Earth, latitude measures how far you are north or south of the equator. In the sky, which coordinate measures how far a star is north or south of the celestial equator? • Which option in the list is specifically defined as an angle north or south of the celestial equator? • Two of the options are angular distances, and two are not pure north–south angles. Can you separate those groups first?

✅ Before You Answer

• Identify which option is an angle measured north or south of the celestial equator, in degrees • Confirm that the west–east coordinate (comparable to terrestrial longitude) is not what the question is asking about • Eliminate any option that describes lines on the sphere rather than the numerical coordinate value itself
