PROBLEM TO BE SOLVED: To realize a terrestrial globe which allows the conceptual understanding of the relative entire bearing relations between a terrestrial globe spherical body 1 and the Earth 19 as well as the sun 18 viewed from an observation point 32. SOLUTION: This terrestrial globe consists of a sunshine hemispherical film 3 which indicates a sunshine area 25 fixed to an observation bearing surface pedestal 4, a nighttime hemispherical film 2 which indicates a nighttime area 26, a month and date adjusting rotary pedestal 5 which rotates on this pedestal 4, a time adjusting dial 6 which revolves and rotates on this pedestal 5, a time setting month and date scale 7 which matches the phase of the scale to the pedestal 5 and revolves, the terrestrial globe spherical body 1 which simulates the Earth, a horizontal level 9 and a magnetic bearing gage 8.
