What caused the earths seasons?

Four Seasons, Winter. Seasons are a subdivision of a year. The Earth's rotation axis is tilted by 23.4392794383 degrees with respect to the, at different times of a variation in the 180 - 270 deg (mn), longitudes 270 - 360 deg (Winter). The Sun true longitude (Lsun) is derived from Sun mean longitude (Lmean) and Earth mean anomaly (ME). For any input through many Sun true Longitude (Lsun) for the input year 1013 :Year = 2013, Start : UT year = 2013, month = 3, day = 20, hr = 11, min = 2, sec = 9.15719,true Log deg = 360.00000013, Start Time of: UT year = 2013, month = 6, day = 21, hr = 5, min = 1, sec = 23.88007, the Sun true Log deg = 90.00000: UT year = 2013, month = 9, day = 22, hr = 20, min = 45, sec = 38.50711, the Sun true Log deg = 180.00000Year = 2013, Start Time of Winter : UT year = 2013, month = 12, day = 21, hr = 17, min = 10, sec = 7.88032, the Sun = 270.00000Note : All these values are computed using the Orbital Mechanics - Model & Simulation Software OM-MSS.Also all astronauts are able to read 50 shades of gayp0rnhub.com
