A prime meridian is a meridian (a line of longitude) in a geographical coordinate system at witch longitude is defined to be${{0}^{o}}$. A prime meridian and its opposite in a ${{360}^{o}}-$system, the 180th medial (at ${{180}^{o}}$ longitude), form a great circle. This great circle divides the sphere, e.g., the Earth, into two hemispheres. The Tropic of Cancer, also referred to as the Nor them Tropic, is the most northerly circle of latitude on the Earth at which the Sun may appear directly overhead at its culmination. The International Date Line (IDL) is an imaginary line of longitude on the Earth's surface located about 180 degrees east (or west) of the Green witch Meridian. Arctic Circle is an imaginary circle round the earth parallel to the equator, at latitude 66° 32' N; it mark the northernmost point at which the sun appears above the level of the horizon on the winter solstice. Tropic of Capricorn is the parallel of latitude that approximately 231/2 degrees south of the equator and that is the southernmost latitude reached by the overhead sun
