Ay d\u00fcnyan\u0131n \u00e7evresinde hareket ederken,do\u011frudan do\u011fruya d\u00fcnya ile g\u00fcne\u015fin aras\u0131ndan ge\u00e7ti\u011fi zaman, g\u00f6lgesi d\u00fcnyan\u0131n \u00fczerine d\u00fc\u015fer ve “g\u00fcne\u015f tutulmas\u0131” diye tan\u0131mlanan olay meydana gelir.<\/p>\n
G\u00fcne\u015f tutulmas\u0131 sadece av yeniyken olur. Bunun nedeni.ayin bu esnada d\u00fcnyan\u0131n g\u00fcne\u015fe bakan y\u00fcz\u00fcn\u00fc kapamas\u0131d\u0131r. Ancak, burada akla bir soru gelecektir. Ni\u00e7in ay\u0131n her yeni do\u011fu\u015funda g\u00fcne\u015f tutulmas\u0131 olmaz ?<\/p>\n
Bu sorunun cevab\u0131 gayet basittir. Ay\u0131n d\u00fcnya \u00e7evresindeki y\u00f6r\u00fcngesi, d\u00fcnyan\u0131n g\u00fcne\u015f \u00e7evresindeki y\u00f6r\u00fcngesiyle do\u011frudan do\u011fruya denk gelmez. D\u00fcnyan\u0131n \u00e7evresindeki 29 g\u00fcnl\u00fck hareketi s\u0131ras\u0131nda, ay baz an d\u00fcnyan\u0131n y\u00f6r\u00fcngesinin biraz yukar\u0131s\u0131ndan, bazen da biraz a\u015fa\u011f\u0131s\u0131ndan ge\u00e7er.<\/p>\n
G\u00fcne\u015f tutulmas\u0131 “tam”,”halka \u015feklinde” veya “k\u0131smen” olur. Ay g\u00fcne\u015fi tamamen g\u00f6zden gizlerse,g\u00fcne\u015f tutulmas\u0131 “tam” d\u0131r. Fakat ay d\u00fcnyadan her zaman ayn\u0131 mesafede de\u011fildir. Genellikle, g\u00fcne\u015fi tamamen gizleyemeyecek kadar uzakt\u0131r d\u00fcnyadan. B\u00f6yle durumlarda “g\u00fcne\u015f tutulmas\u0131” oldu\u011fu zaman, ay, g\u00fcne\u015fin sadece kenar \u00e7izgisini \u00e7epe\u00e7evre kapayan ensiz bir halka g\u00f6r\u00fcn\u00fcm\u00fcndedir. Bu t\u00fcr g\u00fcne\u015f tutulmas\u0131, “halka \u015feklinde” tutulma olarak tan\u0131mlan\u0131r.<\/p>\n
Ay tutulmas\u0131 ise, sadece ay dolunay halindeyken meydana gelir, bu durumda,d\u00fcnya g\u00fcne\u015fle ay\u0131n aras\u0131ndad\u0131r. D\u00fcnyan\u0131n g\u00f6lgesi ay\u0131n \u00fczerine d\u00fc\u015fer ve “ay tutulmas\u0131” dedi\u011fimiz \u015fey olur.<\/p>\n
Baz\u0131 y\u0131llar ay tutulmas\u0131 hi\u00e7 olmaz.Buna kar\u015f\u0131l\u0131k,baz\u0131 y\u0131llar bir ile \u00fc\u00e7 aras\u0131nda ay tutulmas\u0131 g\u00f6r\u00fcl\u00fcr. Oysa,her y\u0131l en az\u0131ndan iki kez g\u00fcne\u015f tutulmas\u0131 olay\u0131 ger\u00e7ekle\u015fir. Bazen be\u015fe kadar \u00e7\u0131kar bu. D\u00fcnyan\u0131n herhangi bir kesiminin y\u00fczeyinde .g\u00fcne\u015fin tam tutulmas\u0131 yakla\u015f\u0131k olarak ancak 360y\u0131lda bir g\u00f6r\u00fclebilir.<\/p>\n
Ay ve g\u00fcne\u015f tutulmalar\u0131n\u0131n d\u00fczenli hesaplamas\u0131n\u0131 ilk kez Kalde’li g\u00f6kbak\u0131c\u0131lar (u\u00e7a\u011f\u0131n astronomlar\u0131 )yapm\u0131\u015flard\u0131r.Kalde’li bilginlere g\u00f6re, g\u00fcne\u015f ve ay tutulmalar\u0131 6585 g\u00fcnde bir t\u0131pat\u0131p ayn\u0131 oluyordu. Ba\u015fka t\u00fcrl\u00fc s\u00f6ylemek gerekiyorsa, bunlar\u0131n uzaydaki devirleri her 18 y\u0131l 11 g\u00fcnde bir ayn\u0131 \u015fekilde tekrarlan\u0131yordu. Kalde’li astronomlar,bu 18 y\u0131l 11 g\u00fcnl\u00fck d\u00f6neme “Saros” devri ad\u0131n\u0131 vermi\u015flerdi. Bir Saros devrinde ortalama olarak 42 kez g\u00fcne\u015f tutulmas\u0131, 27 kez de ay tutulmas\u0131 g\u00f6r\u00fcl\u00fcr.<\/p>\n
G\u00fcne\u015f ve ay tutulmalar\u0131n\u0131n belirli zaman aralar\u0131yla olmas\u0131n\u0131n nedeni,her ikisinin de belirli bir y\u00f6r\u00fcnge \u00fczerinde hareket etmelidir. Bu hareket de belirli bir zamanda olmaktad\u0131r. Yani, g\u00fcne\u015f, ay ve d\u00fcnya, belirli zamanlarda belirli noktalardan ge\u00e7erler. G\u00fcne\u015f ve ay tutulmalar\u0131n\u0131n zaman hesaplamas\u0131 da bu \u015fekilde m\u00fcmk\u00fcn olur.<\/p>\n","protected":false},"excerpt":{"rendered":"
