Ilanga liyinkanyezi, ibhola elikhulu elibomvu elibomvu, elisekude kakhulu kusuka kwiplanethi yethu. Esibhakabhakeni, kubonakala kuncane impela futhi akukulula ukucabanga ukuthi le "ibhola" ishisa kanjani izwe lonke. Konke kumayelana nebanga, ngoba empeleni iLanga lingamakhulu ezikhathi eziningi.
Ngabe ibanga ukusuka elanga lilinganiswa kanjani?
Ukuthola ibanga ngqo elangeni, amaGrikhi asendulo azamile, okwakungaphumeleli, ngoba izindlela zokuhlala zazingemuva. Izibalo zokuqala zakwazi ukuhambisa i-cassini ne-riher ngo-1672. Ukubuka isikhundla sikaMars nokusebenzisa izibalo zejometri, babeka ibanga elilinganisiwe - amakhilomitha ayi-139 million.
Engxenyeni yesibili yekhulu le-XX, ososayensi basebenzise indlela ye-radar. Umnyombo wayo ulele ekudluliseni kwento ye-pulse - kuboniswe kuyo, umfutho ubuyela emuva. Ngokusekelwe kwidatha, lapho kwenzeka khona kusuka emhlabathini uye elangeni nasemuva, kwenziwa izibalo ezinembile.
Ukukala isikhala sangaphandle, amanani anjengama-purares kanye nonyaka wokukhanyisa nawo asetshenziswa. Unyaka wokukhanya yibanga lapho ukukhanya kuwunqoba unyaka owodwa "womhlaba". Ijubane lokukhanya licishe libe yizigidi ezingama-300 m / s, unyaka wokukhanya ulingana no-9,46073047 × 1012 km.
Iqiniso Elithakazelisayo: Ibanga elisuka elangeni liye emhlabeni imizuzu eyisishiyagalombili ekhanyayo. Sekuyisikhathi esiningi udinga ukukhanya kwelanga ukufeza iplanethi yethu.
Ibanga eliqondile ukusuka elangeni liye emhlabeni ngamakhilomitha ayi-150 ezigidi. Okujabulisayo, le nkomba iyashintshashintsha phakathi nonyaka, njengoba i-orbit yeplanethi yethu inefomu le-ellipsoid. NgoJulayi, kungamakhilomitha ayi-152, kwathi ngoJanuwari - amakhilomitha ayi-147.
Yiziphi izehlakalo ezingathinta umjikelezo womhlaba?
Ukuze ulinganise kahle ushintsho ebangeni phakathi koMhlaba neLanga isikhathi eside kunzima kakhulu. Ngakho-ke, ososayensi bakha imibono ngesisekelo sokubonwa kanye nemodeli ehlukahlukene ehlukahlukene yokuthuthukisa imicimbi.
Njalo ngonyaka, iplanethi yethu isuswa elangeni cishe ngo-1.5 cm. Kunethonya lezinto ezahlukahlukene. Kakhulu inhlonto yenuzi, eyenzeka elangeni. Iqiniso ngukuthi ngomzuzwana ngamunye ngenxa yale nqubo, ilahlekelwa amathani acishe abe ngu-4,000,000. Ngomzimba omkhulu kangaka wezulu, lesi yinkomba encane, kepha kancane kancane inyusa umhlaba orbit.
Ezigabeni zokuqala zobukhona, ilanga lalizungezwe yi-disc protoplanetic (gaseous). Manje umhlaba ubhekene nalezi zinhlayiya zento, okuthinta nokujikeleza kwayo - kushintsha cishe ngosayizi weproton (1 femometre noma 10-15 m).
Kuthinta amandla adonsela phansi emhlabeni, izinto ezihlukile ezinhle kakhulu ohlelweni lwelanga. Ngayinye yalezi zinhlaka zasezulwini inamandla athile okuheha. Kunethuba lokuthi imidwebo yedatha yamandla adonsela phansi ingathinta ushintsho lwe-orbit.
Ilanga lilindele ngokungafanele ngesiphetho soshintsho esiqwini esibomvu. Uma kwenzeka, i-kernel izokhula ibe namandla ngokwengeziwe, igobolondo langaphandle lizokhuphuka kakhulu ngosayizi kanye nenqubo yokuhlanganiswa kwe-helium izoqala. Lokho wukuthi, ilanga lizoqala ukugqamisa amandla amaningi.
Ukuba inkanyezi ebomvu enkulu, kuzobhubhisa amaplanethi athile. Isibonelo, iVenus neMercury kunganyamalala. Iplanethi yethu nayo ingaba phakathi kwabo, kepha kungenzeka ukuthi kuneqiniso lokuthi lizobhubhisa. Kulokhu, umhlaba kufanele ususwe ngokuphelele elangeni - cishe ngo-15% futhi uqhubeke kabusha irediyo yamanje.
Iqiniso Elithakazelisayo: Iminyaka yelanga ineminyaka engaba yizigidi eziyizinkulungwane eziyi-1,6. Imayelana nokujikeleza kwayo impilo yayo.
Eminye imizimba ye-galactic nayo ingathinta umjikelezo womhlaba, yenza kungazinzi. Kwesinye isikhathi lezi zinto zenzeka eduze kwesimiso sethu sonozungezilanga - lokhu kwenzeka kungavamile. Ukuqina kwe-orbit kusongela ukunyakaza kweplanethi kuze kuphume umthala.
Uma umhlaba usabasinda ukuguqulwa kwelanga kube yisiqhwaga esibomvu, kuzohlala "kuboshwe" kukho. Ngaphezu kwalokho, iplanethi yethu izoqala ukunciphisa ibanga elangeni. Lokhu kuzothinta imisebe yokudonsa amandla. Umbono ka-Einstein uthi izixuku ezimbili, e-orbit zijikeleza omunye komunye, zikhipha amaza adonsela phansi.
Ososayensi babheka izehlakalo eziningana ezithinta umjikelezo womhlaba kanye nebanga phakathi kwelanga neplanethi yethu. Kuze kube manje, ithonya elinamandla kakhulu linokunye ukuhlanganiswa kwenuzi okwenzeka elangeni. Futhi, umjikelezo womhlaba ungashintsha ngenxa yokungazinzi kwenqwaba, ukuguqulwa kwelanga esiqwini esibomvu. Okungenzeka kakhulu yi-hypothesis yokufakwa komhlaba ngeLanga eminyakeni eyizinkulungwane eziningana.
