Azimuth
• azimuth This is the
direction of a
celestial object,
measured clockwise
around the
observer's horizon
from north. So an
object due north has
an azimuth of 0°,
one due east 90°,
south 180° and west
270°.
Altitude
• altitude The angle of a
celestial object measured
upwards from the
observer's horizon. Thus,
an object on the horizon
has an altitude of 0° and
one directly overhead has
an altitude of 90°. Altitude
is also frequently referred
to as "elevation"

Other vocabulary
• Celestial object –object outside the
atmosphere (planet, star)
• Horizon-The line where the sky and the
ground seem to meet. (sun rises and sets)
• Zenith- Point on the sky directly overhead.
• Elevation -indicate the height of the observer
above sea-level.

to make a pattern

VOCABULARY
Astronomy - study of universe, stars, planets, space
Celestial object –object outside the atmosphere (planet, star)
Horizon-The line where the sky and the ground seem to meet.
(sun rises and sets)
Azimuth –This is the direction of a celestial object, measured
clockwise around the observer's horizon from north
Altitude- The angle of a celestial object measured upwards from
the observer's horizon
Zenith- Point on the sky directly overhead.
Elevation -indicate the height of the observer above sea-level.
Apparent path of star – stars appear to move across the sky
from east to west at a rate of 15 degree/hour because the earth
is rotating
Constellation – a group of stars that appear to make a pattern
(88)
Circumpolar stars – stars that appear to orbit around the
poles and never set.
Ecliptic – apparent path of the Sun against the background
stars (12 constellations centered on ecliptic – zodiac)
The Astrolabe that the Portuguese navigators used on board
ship to calculate the height of the Sun throughout the day.
Using the astrolabe to measure the angle of the Sun above the
horizon.
