I-cosmos yindawo egcwele izinto ezingaziwa namanje ezilindele ukuphendulwa. phakathi kwabaningi, ukuziphatha okungalungile kwamadwala asemkhathini kuyatholakala. Ngokusekelwe ku Ngakho-ke, ukwesaba okucashile komthelela we-asteroid engaba yingozi kuya ngokuya kuphezulu. Nakuba okwamanje abukho ubungozi obuqinisekisiwe, kusewukukhathazeka.
Izikhungo ezifana ne-NASA beziphethe ukuveza lawo matshe amakhulukazi noma ama-asteroids, ahlobene noMhlaba. Izazi zezinkanyezi nawo wonke umphakathi wesayensi wakuleso sikhungo ucacisile ukuthi mancane amathuba okuba nomthelela. Bancane kakhulu, kodwa akukaze kube buhlungu ukwazi ubuso nobuso ukuthi yini elandela iplanethi.
Ungase futhi ube nentshisekelo esihlokweni sethu: Uyafuna ukufunda okwengeziwe mayelana nemikhumbi-mkhathi? Lapha uzokwazi konke!
Incazelo efingqiwe kakhulu neqondakalayo ye-asteroid engaba yingozi isilapha!
Emkhathini, sekuphethwe ukuthi yonke into ixhumene ngokungaqondile. Njalo izikhathi eziningi izenzakalo zezinkanyezi ziyenzeka ezihlobene namaplanethi noma ukudlula kwezinkanyezi ezinomsila endaweni yonke.
I-anecdote ngayinye eye yenzeka endaweni yonke enkulu inesici esifanayo esiye sacwaningwa kusukela ezikhathini zasendulo. Le khwalithi ayilutho futhi ayikho ngaphansi kwe-orbit noma umzila wento ethile yasemkhathini.

Kwezinye izikhathi, imigudu yemizimba eyahlukene ijwayele ukuhlobana, ukuheha noma ukuxosha. Ngenxa yalokho, ukungqubuzana, imithelela, ukuchezuka noma ezinye izehlakalo ezithakaselwayo ziyaqala.
Ukwazi lokhu, i-asteroid engaba yingozi i-asteroid, i-meteor noma inkanyezi enomsila eseduze noMhlaba. Kubhekwa kanjalo ngoba i-orbit yayo ihlangana noMhlaba ngebanga elincane, ngengozi ethile yomthelela.
Kufanele kuqashelwe futhi ukuthi nakuba zingekho izingcuphe manje noma esikhathini esizayo zomthelela, yizinto okungafanele zilahleke. Kungenjalo, imiphumela ingaba mibi kakhulu noma ingakhiqizi kakhulu.
Ngakolunye uhlangothi, i-asteroid engaba yingozi yaziwa nangokuthi into ekwazi ukudala umonakalo. Ngokuya ngosayizi, isivinini namandla okuthinta, kungase kungabonakali noma kubangele izikhathi ze-apocalyptic.
Kulinganiselwa ukuthi lolu hlobo lokushayisana kwe-asteroid okungaphezu kwamamitha angu-50 noma okungaphezu kwekhilomitha eli-1, kwenzeka ngezikhathi ezithile. Kafushane, akuzona izehlakalo ezingazodwa, kodwa ngaphezulu, eziwumjikelezo. Isibonelo esicacile salokhu kwaba ukushabalala kwama-dinosaur ezigidini zeminyaka edlule. Ungafunda kabanzi ngalesi sihloko kokuthi Lesi sihloko mayelana nama-asteroids.
I-asteroid okungenzeka ibe yingozi ngo-2020. Iyiphi (ama) eyasatshwa kakhulu ngonyaka odlule?
Akuyona imfihlo kunoma ngubani ukuthi unyaka wezi-2020 ubufana nenhlekelele ngenxa yezimo ezehlukene ezenzeke. Ukusungulwa kwalolu bhubhane kanye nokuwa komnotho, kanye nokuwa kwezempilo, kubeka ubuntu esimeni.
Futhi uma lokho bekunganele, izinkinga zasemhlabeni zazingelutho uma ziqhathaniswa nezendawo yonke. Ngonyaka odlule, akuyona nje i-asteroid eyodwa engaba yingozi ngo-2020 eye yabangela ukwesaba, kodwa eziningana zazo. Ukuze uthole imininingwane eyengeziwe ngalokhu, ungabheka isihloko ku ama-asteroids ahlasela uMhlaba ngo-2020.
I-asteroid engaba yingozi ngo-2020 bekungaba i-icing ekhekheni. Nokho, badlula benganakile ngaphandle kokubanga lutho ngaphandle kokwethuka okuncane. Ngisho nezinye zazo zazingaziwa kangako.
Noma kunjalo, emphakathini wesayensi, izinyanga zikaJulayi noNovemba zazinokushuba okukhulu. Ngokuqondile ngalezo zigaba zekhalenda, izinto ezinamatshe ezinamandla kakhulu eduze noMhlaba wonyaka zabonwa.
Ngokungangabazeki, noma yikuphi ukubala kabi kwakuyoba inhlekelele. Noma kunjalo, badlula ngokushesha ngaphandle kokushiya noma iyiphi incithakalo endleleni yabo. Ngenxa yokuthi abangela ukuxokozela okungaka phakathi kwezazi zezinkanyezi, kuyafaneleka ukwazi ukuthi zaziyini lezi zinkanyezi.
I-asteroid emangalisayo 2020ND
Ngomhla zingama-24 kuJulayi wonyaka odlule wezi-2020, kwakusho usuku lokungaqiniseki okuphezulu. La NASA Wayebone i-asteroid engaba yingozi engaphezu kwamamitha angu-150 ububanzi isondela futhi isondela.
Ukuhamba ngesivinini esingaphezu kwamakhilomitha ayizinkulungwane ezingu-48 ngehora, emuva ngaleso sikhathi kwakufanekisela usongo lwangempela. Kodwa-ke, ubungozi bokushayisana bekwaziwa ukuthi buncane, ngakho i-asteroid yagcina iqhubekele phambili ngaphezu kwe-5 million km ukusuka emhlabeni.
I-Apollo asteroids engavamile
NgoNovemba ngonyaka odlule, ama-asteroid amabili e-Apollo ayemiselwe ukuba enzeka ngosuku olufanayo. Ngokukhethekile, ngoNovemba 26, 2020, zombili i-Apollo 2020 WPI kanye ne-Apollo 2020 UR6 zizodlula cishe ngesikhathi esifanayo.
Ngokwemininingwane ekhishwe yi-NASA, i-Apollo 2020 WPI asteroid iyona ekhathaza kakhulu laba bobabili. Njengoba inezimpiko eziphakathi kwamamitha angu-300 no-560 ububanzi, ingahamba ngaphezu kwezigidi ezingu-8 km ngesivinini esingu-23 km/s.
Ngakolunye uhlangothi, i-Apollo asteroid 2020 UR6, yayinokulinganisa ngobukhulu obulingana ne-Empire State. Nokho, uma kuqhathaniswa nomfowabo oseduze, ijubane lakhe lokuhamba alizange lidlule izinkulungwane ezingu-20 km / s.
I-asteroid enkulu i-Aten
Inyanga kaNovemba iyona eyasingatha ukubonwa kwezinkanyezi ezingase zibe yingozi. Ngalowo mqondo, i-Atón 2000 W0107, idale ukukhathazeka okukhulu kunalokho okufanele ngenxa yobukhulu bayo bekhilomitha.
Nakuba izokwenzeka endaweni eqhele ngamakhilomitha angaphezu kwezigidi ezine ukusuka eMhlabeni, akazange ahluleke ukubangela ukukhathazeka okucashile. Ngesivinini esingaphezu kuka-25 km/s, ngaphandle kokungabaza, umthelela wayo ubungaba ngaphezu kwe-athomu.
I-NASA ixwayisa nge-asteroid engaba yingozi! Ngabe u-2021 uzofana no-2020?

Izindaba mayelana nesixwayiso se-NASA mayelana ne-asteroid engaba yingozi, Akuzange kuthathe isikhathi eside ukuzungeza umhlaba. I-asteroid 2009 JF1, ehlala ibonwa yilesi sikhungo, ingaba nomthelela ngoMeyi 2022.
Uma unyaka ka-2020 ubufana nobhubhane, uzohlobana nemicimbi yezinkanyezi. Ngokungeziwe kule asteroid eshiwo ngenhla, ngoJanuwari 2020, kuzofika indikimba enamatshe elingana ne-Eiffel Tower.
Njengoba inamamitha angaphezu kuka-250 ububanzi, i-NASA ixwayisa ngesibhakabhaka esingaba yingozi okuthiwa "2016 CO247". Ezindleleni ezinhlanu ezibalwe enyangeni yamanje kaJanuwari, ukulandelelwa kwale asteroid kugqama ngaphezu kwezinye.
Noma kunjalo, ukukhathazeka kuzoba indaba yosuku olulodwa kuphela, ngoba akumeleli isimo sangempela somthelela. Nokho, ukungayiboni kungabangela umcimbi esikhathini esizayo ongafuni ukuwenza.
