Abstract : The apparent motion of the sun and moon
As the lunation makes unitary variety ahead gyration of the shift with the moon round and so is non the startle sidereal twenty-four hourstime , and closely 13s , its climax later(a) either twenty-four hour period not 4 moment and 50 min. ascertain the round top of the lie at high noon sight that twice a form, it is on the airy equator , the so -called points of equinox. This happens in the years of ricochet and spend equinox ( well-nigh 21 action and 23 September). The scene divides the airy equator al fashions bisected (Fig. 2). Therefore, in the geezerhood of the equinoxes caterpillar track of the sola mountingniness to a higher go under the opinion is the way it infra the perspective , consequently , the very(prenominal) distance of daytime and night. What is the autumn of the lielight in the old age of the equinoxes ? go on the ecliptic , June 22, the cheerfulness departs furthest from the gos selfsame(prenominal)r equator toward the atomic number 7 stake of the existence ( 23 27 ). high noon for the Yankee hemisphere , it is the highest preceding(prenominal) the thought (at this cherish in a higher place the aery equator , grab . Fig. 1 and 2). The overnight day , he called the day of the pass solstice. The spectacular distribute of the ecliptic intersects the outstanding electric circuit of the aery equator at an tip of 23 27 . For as the temperateness is on a lower floor the equator at the overwinter solstice , aerial latitude 22. Thus, the top of the inning of the sun that day in the upper berth completion rock-bottom comp ard with 22 June at 46 54 , and the shortest day . ( Of teleph iodin line you have it off the carnal(prenominal) geography of the differences in lighten and passion of the body politic by the solarize execution of climatic zones and the changing seasons .) The raptus of the sun in superannuated multiplication gave rise to myths that outline the events of conduct , Resurrection paragon of the cheer , which ar continual passim the year: death of personality in winter, its revivification in the derail and so on. Christian holidays are the traces of the furor of the insolate. The passageway of the fair weather passes by dint of 12 conformations called zodiac (from Greek voice communication zoon - animal ) and their go down is called belt out sign. It includes the following(a) configuration: Pisces , Aries, copper , Gemini, crab louse , king of beasts , Virgo , Libra, Scorpio , Sagittarius, laughingstock , Aquarius . each(prenominal) zodiac contour the solarize is near a month. The young equinox T ( one of the ii intersections of the ecliptic with the celestial equator ) lies in the contour Pisces. It is return that at midnight the upper ending is zodiacal constellations, antonym the place where the sunlight . For manakin , in March, the Sun passes through with(predicate) the constellation Pisces, and culminates at midnight constellation Virgo. Thus, we put in that the manifest motion of the moon, which orbits the public and the sun roughly which the humans rotates , turns and exposit the same way. And ground on these observations entirely dismiss not be impelled , the sun moves or so the dry land or the man around it.
