Kukho iziganeko zeenkwenkwezi ezenzeka rhoqo kumakhulu eminyaka. Enye yazo kukuhamba kweVenus. Yinto yesayensi yeenkwenkwezi eyenzeke kuphela amaxesha asixhenxe ukusukela oko kwasungulwa iteleskopu. Kwenzeka ngeminyaka yoo-7, 1631, 1639, 1761, 1769, 1874 nowama-1882. Ixesha lokugqibela ukubonwa kwaba nge-2004 kaJuni ka-6. Imalunga nokuhamba kweVenus kusika i-solar disk.
Kule nqaku siza kukuxelela malunga nokuhamba kweVenus malunga nokuba zeziphi iimpawu zayo kunye nomnqweno.
Kukuphi ukuhamba kweVenus
Ukuhamba kweVenus sikubiza ngokuba yindlela ebonakalayo yale planethi phambi kwediski yelanga. Ukusuka emhlabeni unokujonga kuphela ukuhamba kwezo iiplanethi zangaphakathi kwindlela yayo. Umzekelo, ukuhamba kweMercury kwinqanaba Amaxesha ali-13 ngekhulu leminyaka kunye nalawo eVenus kwizinga le-13 ngewaka leminyaka. Ukuba imijikelezo yezinye iiplanethi ezinje ngeMercury, iVenus kunye noMhlaba zikwinqwelomoya efanayo, ukuhamba kweendlela ezimbini zokuqala kuya kuba rhoqo. Nangona kunjalo, oku akunjalo. Inyani yokuba kumanqanaba ahlukeneyo e-orbit, yenza ukuhlangana kungabi rhoqo. Ngamanye amaxesha ungabona ukuhamba kunika iplanethi enkosi kukuwela kweediski.
Ukusuka kwindawo yokujonga umhlaba, iMercury kunye neVenus banokungena ngokudibeneyo kwaye bangangeni kwidiski yelanga, kodwa badlule kumazantsi alungileyo emantla enkwenkwezi. Siyayazi loo nto I-orbit kaMercury ine-7 ° ngokubhekisele kuMhlaba, kunye neVenus ka-3,4 °. Ngezi meko ze-orbit esekwe, kufuneka sazi ukuba zeziphi iimeko ezibangela uhambo. Umdibaniso osezantsi weplanethi yangaphakathi uvela xa ukwenye yeendawo ze-orbital. Ngale ndlela, loo manqaku e-orbit ngalawo anqumla inqwelomoya yokujikeleza kweplanethi yethu. Kule meko kuphela, ilanga kunye neplanethi yoMhlaba zikwimeko ethe tye kwaye kunokwenzeka ukuba uqaphele ukugqitha kweplanethi phambi kwediski yelanga.
Ukuhamba kokugqibela kwe-mercury kunokujongwa kwi-2016, ngelixa uhambo lweVenus kuye kwafuneka ukuba ludlule ngaphezulu kwenkulungwane ukuze lubonwe. Isibini esilandelayo sokuhamba kule planethi siyakwenzeka ngaphezulu kwenkulungwane emva kweenkampani ezikude ezinje UDisemba 10, 2117 noDisemba 8, 2125.
Ukuhamba kweVenus ngokusebenzisa idiski yelanga
Ukuhamba kweVenus phambi kwediski yelanga kukhangeleka ngakumbi kuneMercury. Kungenxa yokuba ububanzi obubonakalayo bukhulu kakhulu ngenxa yokusondela kweplanethi yethu. Siyazi ukuba idiski yeVenus ingama-61 ″ ububanzi (1/30 ubukhulu belanga) iphindwe kahlanu kunediski yeMercury, efikelela kuphela kwi-12 ″. Le yimbono evela kwiplanethi yethu.
Olu hambo lwenzeka ngeentsuku zokuqala zikaJuni nangoDisemba xa ilanga libekwe ngaphantsi kwe-1 ° 45 'ukusuka kwindawo kwaye iplanethi ifikelela kwezona ndawo zidibeneyo. Izazi ngeenkwenkwezi ziluchaze olu hlobo lwesenzeko njengezinto ezinqabileyo kwaye zenzeka kuphela emva kosuku okanye ezimbini zemihla apho iplanethi yethu idlula kwiindawo. Siyazi ukuba zenzeka rhoqo rhoqo kwaye zihlala zingaphaya kweminyaka engama-243.
Siza kubona ukuba zeziphi ezona ziganeko ziphambili zenzekayo ngexesha lokuhamba kweVenus ukuqaqambisa ukubaluleka kwale meko:
- Umfowunelwa wokuqala: Kule ndawo yokuqala yokunxibelelana, kufuneka ukuba idiski ibambe idiski yelanga. Oku kukuqala kohambo kwaye kamva kuya kuqatshelwa ukuba yaziswa njani kuyo. Oku siyazi ukuba akunjalo kwaphela, kodwa kuyimbonakalo ebonakalayo.
- Umfowunelwa wesibini: Yinxalenye yale meko apho idiski yeVenus ijijeke ngaphakathi kwidiski yelanga. Siyabona ukuba inqaku elimnyama lihamba ngelanga ngokuhamba ngokulinganayo ngokufanayo. Ngaphezulu okanye ngaphantsi unokuqikelela isantya malunga nemizuzu emi-4 yearc ngeyure. Ukuhamba phakathi kwabafowunelwa ababini kungathatha iiyure ezininzi.
- Umfowunelwa wesithathu: Kulapho idiski yeVenus ichukumisa umda wediski yelanga.
- Iinkcukacha ezine: kukuphela kokuhamba kweVenus. Kule nxalenye yohambo, ii-discs zidibana neetangents zangaphandle.
Kunokuthiwa oonxibelelwano bokuqala babini bachazwa njengesigaba sokufaka kwaye okokugqibela kuthathwa njengesiseko semveliso.
Ungayibukela njani
Olu hambo lokugqibela lwenzeka ngaphezulu kweminyaka esi-8 eyadlulayo, kodwa iimeko ezithile kuye kwafuneka ukuba kuhlangatyezwane nazo ukuze zikubone kakuhle. Ihlale iiyure ezingama-6 kunye nemizuzu eli-12 kwaye yenzeka phakathi kwe-22: 09 pm kunye ne-04: 49 i-UT (iiyure ezimbini ezongezelelweyo zexesha laseSpain peninsular), ke ibingabonakali kakuhle kumacala ethu. In Spain kwinxalenye usingasiqithi kwafuneka ukuba baye kude emantla kangangoko kunokwenzeka kwaye kwiindawo eziphakamileyo ukuba babe tyaba kwaye ecacileyo umphezulu kolundi. Kufuneka ithathelwe ingqalelo ukuba idiski yelanga ishiya uhambo ngexesha layo lokugqibela. Le mizuzu yokugqibela ngumfowunelwa wesithathu nowesine. Oku kubangela ukuba ukuphakama kwelanga emhlabeni ngamaqondo nje ambalwa.
Ingabonakala kwindawo efanelekileyo Kwakunxweme lwaseGirona ngokujonga ngokuthe ngqo ulwandle ekwindawo apho ilanga liphuma khona. Eyona ndawo ilungileyo yokuyijonga usingasiqithi kuthe nca kunxweme lwaseGirona ngombono othe ngqo wolwandle apho ilanga liza kuphuma khona.Ubungakanani beVenus obonwe eMhlabeni ngexesha lokudibana okungaphantsi malunga ne-60 ″, okanye i-3 % ubungakanani be-angular belanga, ngokwaneleyo ukuba bunokubonwa ngaphandle kwesidingo secebo lokujonga.
Ndiyathemba ukuba ngolu lwazi ungafunda ngakumbi malunga nokuhamba kweVenus kunye neempawu zayo.
