Amasonto namasonto emhlabeni wonke

Ku-Venus, iplanethi ijikeleza kancane kancane ukuthi ushintsho olulodwa luthatha isikhathi eside kunalokho okudingayo ukugibela ilanga. Usuku alufana nanoma yikuphi, futhi unyaka awufana nayo. Lapha uzoba nethuba lokuzisebenza ngazo zombili, kunoma iyiphi iplanethi.

Usuku neminyaka yimibiko emibi, futhi izwe ngalinye lizibeka ngendlela ehlukile.

Bona

imini yisikhathi esithathayo izwe ukujikeleza kabili. A-M_BAR_Isi-Italian unyaka yisikhathi esingakanani esithatha ukudlula kabili enyakatho yelanga. Ezweni lezi ziyihora ezingama-24 nezinsuku eziyi-365. Ezinye izwe zihlukile kakhulu.

Izwe	Ubude bemini	Ubude beminyaka
i-Mercury	Izinsuku ze-176	Izinsuku ze-88
i-Venus	Izinsuku ze-117	225 Izinsuku zeplanethi
Iplanethi	Amahora angama-24	Izinsuku ezingama-365
i-Mars	24 amahora 40 imizuzu	687 Izinsuku zeplanethi
i-Jupiter	Amahora angu-9.9	11.9 Iminyaka yeplanethi
i-Saturn	10.7 amahora	29.4 Iminyaka yeplanethi
i-Uranus	17.2 amahora	Iminyaka ye-84 yeplanethi
i-Neptune	16.1 amahora	Iminyaka ye-164.8 yeplanethi

Ezinye izimangalo:

• Iyasebenza i-Mercury, usuku olulodwa (ukuvuka kwelanga kuya kuvuka kwelanga) luthatha iminyaka emibini.
• I-Venus ijikeleza emuva futhi ngokucophelela.
• Amaplanethi amakhulu ajikeleza ngokushesha kunawo wonke, nakuba yizikhulu.
• A-M_BAR_Isi-Italian i-Mars usuku cishe ifana nethu, okuyinto efanelekayo amaqembu rover emhlabeni.

Sebenzisa indawo yokuqhathaniswa ngaphansi kwe-orery ukuqhathanisa noma iyiphi iplanethi.

Ukuqonda

Kunezinhlobo ezimbili zosuku, futhi ushintsho lubalulekile.

• Imini ye-sidereal yisikwele esisodwa esilinganiselwa kuma-stars asendaweni. Isikhathi sezulu yihora le-23, imizuzu engu-56, imizuzwana engu-4.
• I- Imini yelanga isuka emini eyodwa kuya kweyesibili. Lapho i-Earth ijikeleza, iyahamba futhi cishe ngo-1/365 yendlela ejikeleze i-orbit yayo, ngakho kufanele ishintshe kancane (ibanga elingu-1) ngaphambi kokuba ilanga libuye liphezulu. Lokhu kuthatha cishe imizuzwana engu-4, okunikeza amahora angu-24.

Kuplanethi eziningi, izinsuku ezimbili zifana kakhulu. Ku-spinners ahamba kancane, bahlukile kakhulu. I-Mercury ijikeleza kabili ngezinsuku ezingu-58.6 zeplanethi, futhi unyaka wayo unezinsuku eziyi-88. Izinkanyezi ezimbili zihlanganisa ukuze usuku olulodwa lwelanga luthathe amahora angama-176 eplanethi: cishe iminyaka emibini yeMercury. I-Mercury ijikeleza izikhathi ezithathu ngokucophelela ngazo zonke izindiza ezimbili, ukuvala okubangela amagagasi elanga.

I-Venus ijikeleza emuva (ibuyela emuva), kanye ngazo zonke izinsuku zeplanethi ezingu-243. Ngenxa yokuthi ukujikeleza nokujikeleza kweplanethi kuhamba ngendlela ehlukile, zihlanganisa, futhi usuku lwelanga luncane kunalo lokujikeleza: cishe amahora angama-117 emhlabeni.

Unyaka uthatha isikhathi eside uma kuqhathaniswa nokuhamba ngenxa yezizathu ezimbili: indlela ihlala isikhathi eside, futhi iplanethi ihamba kancane. Izwe lihamba ngamakhilomitha angama-29.8/s; iNeptune ihamba ngamakhilomitha angama-5.4/s ngendlela engaphezu kwamaphesenti ayi-30.

Umphathi

Imini yelanga ilandela imikhawulo emibini yokujikeleza. Ngesikhathi sokugqugquzela i-sidereal P_rot (engenalutho uma kukhulunywa nge-retrograde) kanye nesikhathi se-orbital P_orb, zombili zilinganiselwa ngandlela efanayo:

1 / P_solar = 1 / P_rot − 1 / P_orb

Khangela i-Earth: 1/0.99727 − 1/365.256 = 1.00274 − 0.00274 = 1.00000 ngosuku, ngakho P_solar = 1 usuku.

Khangela iMercury: 1/58.646 − 1/87.969 = 0.017052 − 0.011368 = 0.005684, ngakho P_solar = 175.9 izinsuku.

Qinisekisa iVenus (i-retrograde, P_rot = −243.018 izinsuku): 1/(−243.018) − 1/224.701 = −0.004115 − 0.004450 = −0.008565, ngakho |P_solar| = 116.75 izinsuku. Iphawu lokucisha litshela ukuthi ilanga liphuma enyakatho yeVenus.

Unyaka ulandela umthetho wesithathu kaKepler: T² ∝ a³ kuwo wonke ama-orbit elanga. Nge-T eminyakeni futhi a ku-au, T = a^1.5. I-Neptune ku-a = 30.07 au inikeza uT = 30.07^1.5 = 164.9 iminyaka, elingana nokubona 164.79. Ushintsho oluncane luvela ekujikelezeni kanye nesisindo esincane seplanethi, esizofakazelwa yiNewton’s version of the law.
