In the horizon system of coordinates what is equivalent to the parallels of declination of the celestial equator system?

🔍 Key Concepts

• Celestial equator system vs. horizon system – what each uses as its basic reference circles • Declination – what it measures from which reference line or circle • In the horizon system, which coordinate changes in a way similar to how declination changes in the equatorial system?

💭 Think About

• First, recall the definition of declination: is it measured from the celestial equator or from the horizon? Up or around? • In the horizon system, think about which coordinate tells you how far a body is above or below the horizon, similar to how declination tells you how far a body is north or south of the celestial equator. • Look at each option and ask: is this something measured along the horizon, around the horizon, or up/down from the horizon?

✅ Before You Answer

• Be clear on the difference between circles parallel to the celestial equator and circles related to the horizon. • Verify which horizon-system quantity is drawn as a set of parallel small circles on the celestial sphere, just like declination circles are parallel to the celestial equator. • Check that the option you choose is a type of coordinate line (a family of circles), not a single angular distance.
