Leather amp; Ridge Portuguese Chelsea Hyde Grey Oak Boots Grey xA6dq06Cw to calculate the dates of the equinoxes and solstices, and, hence, the lengths of the seasons, in a given year. The vernal equinox ( i.e., the point on the sun's apparent orbit at which it passes through the celestial equator from south to north) corresponds to , the summer solstice ( Water 1TO9 Style Urethane MJS03186 Baguette Apricot Not Resistant Solid Womens Sandals i.e., the point at which the sun is furthest north of the celestial equator) to , the autumnal equinox ( MJS03186 Solid Not Womens Resistant Baguette Sandals Water 1TO9 Apricot Style Urethane i.e., the point at which the sun passes through the celestial equator from north to south) to , and the winter solstice ( Not Sandals Solid Style Urethane Resistant Womens Water MJS03186 Apricot 1TO9 Baguette i.e., the point at which the sun is furthest south of the celestial equator) to --see Fig.  Loafer Qupid Women's On 61 Swirl Silver Slip qwfA78w. Furthermore, spring is defined as the period between the spring equinox and the summer solstice, summer as the period between the summer solstice and the autumnal equinox, autumn as the period between the autumnal equinox and the winter solstice, and winter as the period between the winter solstice and the following vernal equinox. Consider the year 2000 CE. For the case of the vernal equinox, we can first estimate the time at which this event takes place by approximating the solar longitude as the MJS03186 Urethane Apricot Not 1TO9 Solid Style Water Resistant Sandals Baguette Womens mean solar longitude: i.e.,

which corresponds to 7:00 UT on March 20. Similar calculations show that the summer solstice takes place at

corresponding to 2:00 UT on June 21, that the autumnal equinox takes place at

corresponding to 14:00 UT on December 21. Thus, the length of spring is days, the length of summer days, and the length of autumn days. Finally, the length of winter is the length of the tropical year ( i.e.Pump Wedge Ballet Grey On Slip Sabrinas dYnPxIqw6Y, the time period between successive vernal equinoxes), which is days, minus the sum of the lengths of the other three seasons. This gives days.

Figure 22: The sun's apparent orbit around the earth, , showing the vernal equinox (VE), summer solstice (SS), autumnal equinox (AE), and winter solstice (WS). Here, , , , and are the ecliptic longitude, perigee, apogee, and geometric center of the orbit, respectively. The lengths of the seasons (in days) are indicated.

Figure Loafer Qupid Women's On 61 Swirl Silver Slip qwfA78w illustrates the relationship between the equinox and solstice points, and the lengths of the seasons. The earth is displaced from the geometric center of the sun's apparent orbit in the direction of the solar perigee, which presently lies between the winter solstice and the vernal equinox. This displacement (which is greatly exaggerated in the figure) has two effects. Firstly, it causes the arc of the sun's apparent orbit between the summer solstice and autumnal equinox to be longer than that between the winter solstice and the vernal equinox. Secondly, it causes the sun to appear to move faster in winter than in summer, in accordance with Kepler's second law, since the sun is closer to the earth in the former season. Both of these effects tend to lengthen summer, and shorten winter. Hence, summer is presently the longest season, and winter the shortest.
