Altitude: the object"s angle upwards from the horizon. Azimuth: the object"s direction a long the horizon: a celestial body"s position can also be described by its absolute coordinates relative to the ce le s tia l equa tor (ce): Declination (dec): the object"s angle n or s of the ce. E. g: - the full moon"s length spans 0. 5 in the sky. N-he mis phe re : we s e e a ll cons te lla tions n of the ce.
