Xa sijonga isathelayithi kwiplanethi yethu, kubonakala ngathi isondele kakhulu kunokuba injalo. Kwaye ngaba Umgama ukusuka emhlabeni ukuya enyangeni yinto ekuzanywe ukuyilinganisa iminyaka emininzi ukufumana umbono wokuba iyintoni na indalo. Ukufumana umbono womgama phakathi kweplanethi yethu kunye nesathelayithi, siza kusebenzisa imifanekiso kunye neenkcazo ukwenza ukuba kube lula ukuyiqonda.
Kweli nqaku siza kukubonisa ukuba ungakanani umgama ukusuka eMhlabeni uye enyangeni kunye nendlela yokubala.
Umgama ukusuka eMhlabeni uye eNyangeni
Ngokuqinisekileyo amaxesha amaninzi sivile ngomgama phakathi kweplanethi yethu kunye nesathelayithi yayo ngamanani. Ngokukodwa kukho iikhilomitha ezingama-384.403 zomgama. Njengoko bekulindelekile, lo mgama yinto engaqondakaliyo ebantwini, kuba asiqhelananga nokuhamba le migama. Eli nani liphindaphindwe amatyeli amaninzi ngokungathi liphulukene nomxholo kunye nentsingiselo yalo.
Kubonakala ngathi yinto engachanekanga kwaye ayivezi nayiphi na idatha ekhethekileyo. Xa sifunda lo mfanekiso sinokucinga ukuba ngumgama omde ngokwahlula kuwo. Nangona kunjalo, ingqondo yethu ayinakubuqonda ubukhulu balo mgama. Kuba siqhele ukubona inyanga eMhlabeni kwaye ibonakala ngathi inkulu kuthi, inokusenza sibonakale ngathi sisondele kakhulu kunokuba injalo.
Ukuqonda kancinci malunga nomgama kufuneka sijonge kwifoto yokuqala yesi sihlokwana ukubona isikali esinyani ngakumbi. Xa sibona ifoto sinokuhlalutya ingxaki yokulinganisa lo mgama wabantu.
Imvelaphi yokubala komgama ukusuka eMhlabeni ukuya enyangeni
Kubalwa okokuqala umgama phakathi kweplanethi kunye nesathelayithi Kwakukho ngo-150 BC nguHipparchus. Ukulungiselela ukubala lo mgama, wawusekwe kumjikelo wesithunzi esiveliswa yiplanethi yethu enyangeni ngexesha lokusithwa kwelanga yinyanga. Ngelo xesha, umgama wawungachanekanga ngokupheleleyo, kuba inani leekhilomitha ezingama-348.000 lafunyanwa. Kuyimfuneko ukuxabisa ukufaneleka kukaHipparchus ukusukela ngetekhnoloji encinci eyayikho ngelo xesha, yayinempazamo engaphantsi kwe-10% yomgama wokwenene phakathi kwala mabutho mabini ezulu.
Enkosi kubuchwephesha esinabo namhlanje sinokubala lo mgama ngokuchanekileyo. Ukwenza oku, ixesha elithathwayo ukukhanya kukuhamba liyalinganiswa ukusuka kwizikhululo ze-LIDAR eMhlabeni ukuya kubabuyisi abasemva ababekwe enyangeni. Nangona kunjalo, umgama linani elikhulu kangangokuba kunzima ukulifaka ezingqondweni zethu.
Ukusinika umbono, phakathi komgama ukusuka eMhlabeni ukuya enyangeni zonke iiplanethi ze inkqubo yelanga. Ngolu thelekiso kunokubonakala ukuba ngokwenene kukho umgama omkhulu. Iiplanethi ezinkulu ezifana Umbhali y Saturn azinkulu ngokwaneleyo ukuba iidayimitha zazo zinkulu kunomgama ophakathi kwezi zinto zimbini zezulu.
Ngalo mfanekiso wentle ngokwaneleyo ukuze umntu akwazi ukutshintsha ngokupheleleyo umbono esinawo womgama phakathi kwenyanga noMhlaba. Ngokwenziwa kwalo mgama nathi sinako uqonde ngcono amandla omxhuzulane afunyanwa yiplanethi yethu xa ibungakanani bayo. Enye into ebalulekileyo kukuvavanya ukuba ingaba umntu ukwazile ukufikelela enyangeni okanye hayi.
Ukuya enyangeni
Ukufumana umbono womgama omkhulu phakathi kwezi zinto zimbini zasemazulwini, siza kucacisa into eqhelekileyo phakathi kwethu. Siza kulingisa uhambo olusuka eMhlabeni luye enyangeni ngemoto. Ngaphezulu okanye ngaphantsi unokuhamba nge-avareji ye-120 km / h emotweni ukuze singahlawuliswa ngesantya.
Ukuba sigqibe kwelokuba sihambe ngenqwelo-mafutha ukuya enyangeni, kungathabatha malunga neenyanga ezintlanu ukuya apho. Kufuneka siyiqonde into yokuba ezi nyanga zintlanu ziya kwenzeka ukuba kuphela xa singazange sime kube kanye kuhambo lonke.
Nokuba kungakucacisa okunye ukuhamba okude njengeyona nkwenkwezi ikufutshane esinayo, singayithatha ngaphezulu kweminyaka emi-4 ndihamba apho. Kungcono singathethi ngokundwendwela umnyele wethu oselumelwaneni obizwa ngokuba yiAndromeda. Lo mnyele ungaphezulu kwezigidi ezi-2 zeminyaka yokukhanya ukusuka kuthi, ke kungcono ukuba ungacingi ukuba kungathatha ixesha elingakanani xa sifuna ukuhamba ngemoto.
Njengoko ubona, ukusukela ekuthetheni kakhulu malunga nomgama osuka eMhlabeni uye enyangeni sidale inani elingabalulekanga kakhulu kwaye elingasixeleli ukuba liyintoni. Ndiyathemba ukuba ngolu lwazi ungawazi ngcono umgama esikuwo isathelayithi yethu.
