ASTRONOMICAL UNIT (AU) THE AVERAGE DISTANCE OF EARTH FROM THE
SUN.
PRECISE RADAR MEASUREMENTS YIELD A
VALUE FOR THE AU OF 149,603,500 KM
LIGHT YEAR THE DISTANCE THAT LIGHT, MOVING AT A
CONSTANT SPEED OF 300,000 KM/S,
TRAVELS IN 1 YEAR. ONE LIGHT YEAR IS
ABOUT 10 TRILLION KILOMETERS
CELESTIAL SPHERE IMAGINARY SPHERE SURROUNDING
EARTH TO WHICH ALL OBJECTS IN THE
SKY WERE ONCE CONSIDERED TO BE
ATTACHED
CELESTIAL EQUATOR THE PROJECTION OF EARTH'S EQUATOR ONTO
THE CELESTIAL SPHERE
CELESTIAL POLE PROJECTION OF EARTH'S NORTH OR SOUTH
POLE ONTO THE CELESTIAL SPHERE
SUCCESS 1/34

AUTUMNAL EQUINOX DATE ON WHICH THE SUN CROSSES THE
CELESTIAL
EQUATOR FOR MOVING SOUTHWARD,
OCCURRING ON OR NEAR SEPTEMBER 22
VERNAL EQUINOX DATE ON WHICH THE SUN CROSSES THE
CELESTIAL
EQUATOR MOVING NORTHWARD, OCCURRING

ABOVE EARTH'S NORTH POLE
SOUTH CELESTIAL POLE POINT ON THE CELESTIAL SPHERE DIRECTLY
ABOVE EARTH'S SOUTH POLE
RIGHT ASCENSION CELESTIAL COORDINATE USED TO MEASURE
LONGITUDE ON THE CELESTIAL SPHERE. THE
ZERO POINT OS THE POSITION OF THE SUN
AT THE VERNAL EQUINOX. MEASURED IN
HOURS, MINUTES, AND SECONDS, AND IT
INCREASES IN THE EASTWARD DIRECTION
