The Sun
The sun is a star at the center of our solar system. It is a hot ball of glowing gases. Its gravity holds the solar system together. The intense heat is produced by the nuclear fusion reaction in its core. The sun is primarily composed of hydrogen and helium.
Annual Sun Angle
The sun culminates at 45.56 altitude in winter and 93.44 altitude in summer. Hence the sun's angle reaches closest to 90.
Day length
A day is counted as the time taken by the Earth to complete one rotation around its axis. It takes about 24 hours. But for stellar days it is of 23 hours 56 minutes and 4.09 seconds.
