What is the star latitude and star declination?
Celestial coordinates. -- The star's latitude on the celestial sphere is the same as the Earth latitude that it seems to follow on its way aroujnd the sky. On the celestial sphere, the latitude is called "declination", and is expressed in degrees. -- The star's longitude on the celestial sphere is its angle, measured westward, from the point in the sky called the Vernal Equinox ... the point where the sun appears to cross the celestial equator in March. On the celestial sphere, the star's longitude is called "Right Ascension", and it's expressed in hours. That certainly seems confusing, but an "hour of Right Ascension" just means 15 degrees of celestial longitude. So, as the sky turns, the point directly over your head moves through the stars by 1 hour of Right Ascension every hour.
