Ubuso beMercury Ezifundweni Zezinkanyezi IMercury iyiplanethi eseduze kakhulu neLanga futhi ingenye yezinto eziyinselele kakhulu ukuzifunda kwezinkanyezi. Ukusondela kwayo eLangeni kwenza kube nzima ukuyibuka usuka eMhlabeni, njengoba ivame ukucwiliswa ekukhanyeni kwelanga futhi ibonakala ngezikhathi ezithile kuphela—ngokuvamile ekuntweleni kokusa noma ukuhwalala. Kodwa-ke, naphezu kwale mingcele, iMercury igcina… Funda kabanzi
Ubudlelwano Bomhlaba Nenyanga Ukuhlangana Kwamaza Amaza angenye yezinto zemvelo ezibonakala kalula ezindaweni ezisogwini: amazinga olwandle ayakhuphuka amahora ambalwa, bese ehla kancane kancane, bese umjikelezo uphinda nsuku zonke. Ngemuva kwalesi sigqi esibonakala silula kukhona ukuxhumana okuyinkimbinkimbi kwamandla adonsela phansi phakathi koMhlaba neNyanga (kanye negalelo leLanga) okwakha amandla okushintshashintsha… Funda kabanzi
INyanga NjengeSathelayithi Yomhlaba INyanga iyisathelayithi kuphela yemvelo yoMhlaba futhi umzimba wasezulwini oseduze kakhulu neplanethi yethu. Ukuba khona kwayo akugcini nje ngokuhlobisa isibhakabhaka sasebusuku kodwa futhi kuthinta izenzakalo zemvelo ezahlukahlukene ezibalulekile empilweni, njengezinga lolwandle, ukuzinza kwe-axis yokujikeleza koMhlaba, kanye nesigqi sesikhathi emasikweni abantu. Kusukela ezikhathini zasendulo, iNyanga... Funda kabanzi
AmaSathelayithi Emvelo Amaplanethi Esimisweni Selanga Isathelayithi yemvelo umzimba wasezulwini ojikeleza iplanethi noma iplanethi encane ngenxa yethonya lamandla adonsela phansi. Esimisweni selanga, amasathelayithi emvelo avame ukubizwa ngokuthi "izinyanga," yize igama ekuqaleni lalibhekisela eNyangeni ejikeleza uMhlaba. Ukuba khona kwamasathelayithi emvelo kungaphezu nje kokuhambisana: kuthinta ukuzinza kokujikeleza kweplanethi, kubangele ukugeleza kwamanzi, futhi kubangele umsebenzi welanga... Funda kabanzi
Ifu Lase-Oort Nemvelaphi Yama-Comet Uma sibheka isibhakabhaka sasebusuku, ama-comet avame ukubonakala “njengezivakashi” ezithakazelisayo—ezikhanyayo, ezinemisila emide, ezivela ebumnyameni, bese zinyamalala futhi iminyaka emashumi, izinkulungwane, noma ngisho nezigidi. Kodwa umbuzo omkhulu uwukuthi: avelaphi ama-comet? Enye yezimpendulo ezibaluleke kakhulu kusayensi yezinkanyezi yanamuhla yi-Oort Cloud, isifunda esicatshangelwayo… Funda kabanzi
Ibhande Le-Kuiper Kwezinkanyezi Ibhande Le-Kuiper lingenye yezindawo ezithakazelisa kakhulu ohlelweni lwelanga, lisebenza njengendawo yokugcina izinto ezincane ezisele enkambisweni yokwakheka kwamaplanethi. Njengoba itholakala kude kakhulu nomjikelezo we-Neptune, ibhande Le-Kuiper liphethe izinkomba ezibalulekile mayelana nendlela uhlelo lwelanga oluguquke ngayo eminyakeni eyizigidigidi ezingu-4,6 edlule. Nakuba livame ukubhekwa njengesifunda… Funda kabanzi
Ibhande Le-Asteroid Esimisweni Selanga Ibhande le-asteroid lingenye yezakhiwo ezithakazelisa kakhulu ohlelweni lwelanga, liqukethe "amabhlogo okwakha asele" avela ekwakhekeni kwamaplanethi. Uma sicabanga ngebhande le-asteroid, sivame ukucabanga ngesifunda esiqinile nesiyingozi sedwala, esihlanganiswe ndawonye, njengokuthile okuvela kwifilimu yesayensi. Eqinisweni, ibhande le-asteroid libanzi kakhulu kunalokho… Funda kabanzi
I-Haumea kanye ne-Makemake ku-Astronomy: Phakathi kobubanzi obukhulu be-Solar System, kunemihlaba emincane ehambahamba kude kakhulu nomjikelezo we-Neptune. Le mihlaba ayaziwa kakhulu njengamaplanethi amakhulu njenge-Jupiter noma i-Saturn, kodwa iphethe izinkomba ezibalulekile ngomlando wokuqala wokwakheka kwe-Solar System.

I-Eris ohlelweni lwelanga I-Eris ingenye yezinto ezithakazelisayo kakhulu ohlelweni lwelanga lwanamuhla, hhayi ngenxa yobukhulu bayo obukhulu, kodwa ngenxa yendima yayo ekuguquleni indlela abantu abahlukanisa ngayo amaplanethi. Selokhu yatholakala ekuqaleni kwekhulu lama-21, i-Eris ibilokhu iphakathi kwengxoxo yesayensi, ekugcineni yaholela encazelweni entsha yeplanethi. Nakuba ikude, ibanda, futhi ibuthakathaka, … Funda kabanzi
I-Ceres njengePlanethi Elincane I-Ceres ingenye yezinto ezithakazelisayo kakhulu ohlelweni lwelanga, ikakhulukazi ngenxa yesimo sayo esiyingqayizivele kanye nomlando omude wokutholakala. Itholakala phakathi kwemizila ye-Mars ne-Jupiter, i-Ceres ihlala esifundeni esaziwa ngokuthi i-Asteroid Belt. Nakuba ihlala ebhandeni le-asteroid, i-Ceres akuyona idwala lasemkhathini elivamile: iyiplanethi yokuqala emfushane eyaziwayo… Funda kabanzi
