• Celestial North and Celestial South Poles.

• East and West Points of Light.

• Arctic and Antarctic Points.

What is the name of the star closest to the Celestial North Pole?

• Rigel

• Vega

• Polaris

• Orion

The Celestial Sphere's coordinates (equatorial system) are related to what Earth system of coordinates?

• Arctic & Antarctic Circles

• Longitude & Latitude

• Tropics of Capricorn and Cancer

• Sonar systems

What the celestial equivalent of "latitude?"

Degrees of declination are divided in smaller parts called...

• hours (arc hours).

• minutes (arc minutes).

• seconds (arc seconds).

• milliseconds (arc milliseconds).

Arc minutes are divided in smaller parts called...

• hours (arc hours).

• minutes (arc minutes).

• seconds (arc seconds).

• milliseconds (arc milliseconds).

What the celestial equivalent of "longitude?" 

• Inclination

• Left Ascension

• Right Ascension

• Declination

What are the units for right ascension?

• degrees

• hours

• arc milliseconds

• kilometers

Each hour of "right ascension" is divided into...

• minutes and seconds.

• degrees.

• arc degrees.

• milliseconds.

In the local sky this is the line that separates the sky in half running from North to South

• zenith

• azimuth

• ecliptic

• meridian
