    The Sun over Phang Nga Bay in Thailand (), at 7:00 a.m. local time on a March morning. The position of the Sun in the sky is a function of both the time and the geographic location of observation on Earth's surface.

  3. Sun path - Wikipedia

    en.wikipedia.org/wiki/Sun_path

    The relative position of the Sun is a major factor in the heat gain of buildings and in the performance of solar energy systems. [1] Accurate location-specific knowledge of sun path and climatic conditions is essential for economic decisions about solar collector area, orientation, landscaping, summer shading, and the cost-effective use of ...

  4. Solar azimuth angle - Wikipedia

    en.wikipedia.org/wiki/Solar_azimuth_angle

    The solar azimuth angle is the azimuth (horizontal angle with respect to north) of the Sun's position. [1] [2] [3] This horizontal coordinate defines the Sun's relative direction along the local horizon, whereas the solar zenith angle (or its complementary angle solar elevation) defines the Sun's apparent altitude.

    en.wikipedia.org/wiki/Tropic_of_Cancer

    The Tropic of Cancer's position is not fixed, but constantly changes because of a slight wobble in the Earth's longitudinal alignment relative to the ecliptic, the plane in which the Earth orbits around the Sun. Earth's axial tilt varies over a 41,000-year period from about 22.1 to 24.5 degrees, and as of 2000 is about 23.4 degrees, which will ...

    Makar Sankranti is celebrated when the Sun's ecliptic longitude becomes 270° measured from a fixed starting point which is in opposition to Spica, [26] i.e. this is a sidereal measure. Uttarayana begins when the Sun's ecliptic longitude becomes 270° measured from the Vernal equinox, [27] i.e. this is a tropical measure. While both concern a ...
