Iako se zimska kratkodnevnica, najkra\u0107i dan u godini, o\u010dekuje 21. decembra, jo\u0161 po\u010detkom slede\u0107e nedjelje, u utorak i srijedu, mrak \u0107e po\u010deti da pada ve\u0107 u 15 \u010dasova, 57 minuta i 17 sekundi, \u0161to zna\u010di da \u0107e tih dana gra\u0111ani imati najmanje raspolo\u017eive dnevne svjetlosti tokom ove zime.<\/p>\n
Kako obja\u0161njava astronom i popularizator nauke Branko Simonovi\u0107, poznato je da je smjena trajanja obdanice i no\u0107i uslovljena godi\u0161njim kretanjem Zemlje oko Sunca i da u tim razli\u010ditim geometrijama polo\u017eaja, Sunce se razli\u010dito zadr\u017eava na nebu.<\/p>\n
\u201eDugodnevica, dakle u trenutku dolaska leta, sun\u010dev luk na nebu je najve\u0107i, odnosno Sunce se najdu\u017ee zadr\u017eava i zbog toga je obdanica najdu\u017ea. Tada je sunce i najvi\u0161e na nebu i samim tim sun\u010devi zraci ja\u010de greju povr\u0161inu zemlje. Dalje, tokom godine dolazimo do prole\u0107ne i jesenje ravnodnevice kada obdanice traju manje vi\u0161e podjednako, a tokom zime sun\u010dani luk je najkra\u0107i i zbog toga se Sunce najkra\u0107e zadr\u017eava na nebu\u201c, ka\u017ee Simonovi\u0107, prenosi portal RTS.<\/p>\n
Me\u0111utim, napominje astronom, treba imati u vidu da onog trenutka kada nastupi zima i kada no\u0107 postane najdu\u017ea, to zna\u010di da \u0107e ve\u0107 od slede\u0107eg dana stvari da se smijene.<\/p>\n","protected":false},"excerpt":{"rendered":"
