The celestial poles are directly above the earth’s north and south poles.
The North Star is Polaris, and sits almost exactly at the north celestial pole. There is no “south star.”
The celestial equator is simply the projection of the earth’s equator in the sky.
LATITUDE = Measured in degrees north or south of the equator.
LONGITUDE = Measured in degrees east or west of the prime meridian. The prime meridian is a longitude line that passes through Greenwhich, England.
Astronomers use declination and right ascension, which are the equivalents of latitude and longitude.
DECLINATION = Latitude
RIGHT ASCENSION = Longitude
