Iyo asteroid Apophis yave iri nyaya yekufarira kukuru uye kunetseka kubva payakawanikwa muna 2004. Pakutanga yaionekwa sengozi inobvira kuPasi, mafambiro ayo akatariswa zvakanyanya nevanoongorora nyeredzi pasi rese. Maitiro ayo muna 2029 ichave yakasarudzika chiitiko chemuchadenga, ichigadzira zvese tarisiro uye zvidzidzo zvesainzi kuti unzwisise zviri nani izvi mitumbi yedenga.
Kunyangwe masvomhu akatonga kunze, parizvino, kukanganisa nepasi redu, kuswedera kunoshamisa kwarichapfuura kunotipa mukana usingaenzaniswi wekuidzidza. Pazasi, isu tichaongorora zvakadzama maitiro ayo, gwara rayo, njodzi dzaimbotariswa, uye mishoni dzemuchadenga dzakarongwa kuiongorora.
Hunhu hweasteroid Apophis
Apophis, ane zita repamutemo rinonzi 99942 Apophis, is asteroid iri muboka reAton, vanova avo vane orbit iri kunyanya mukati mekutenderera kwePasi. Inofungidzirwa kuyera kumativi 335 metres dhayamita, zvichiita kuti ive chinhu chakakura zvikuru pakati pepedyo-Earth asteroids.
Kuumbwa kwayo kunonyanya kuumbwa silicates, nickel uye iron, iyo inoisa mukati meboka re asteroids emhando rocky. Pakutanga yaifungidzirwa kuva yakareba, yakaita senzungu muchimiro, uye pamusoro payo inofungidzirwa kuti inoumbwa nematombo asina kusimba nekuda kwesimba rayo rinokwevera pasi.
Kana iri orbit yayo, Apophis inotora inenge 0,9 makore ePasi kuti apedze kutenderera kumwe kutenderedza Zuva. Nekudaro, mafambiro ayo anozoshandurwa mushure mekupfuura kwayo pedyo nePasi muna 2029, ichiwedzera nguva yayo yekutenderera kusvika. 1,2 makore.
Iyo trajectory uye maitiro ayo kuPasi muna 2029
Chiitiko chikuru chemuchadenga chine chekuita neApophis chichaitika Kubvumbi 13, 2029, apo ichaita kuti isvike pedyo nePasi. Panguva iyoyo, zvichava zvakarurama Makiromita 32.000 kubva pamusoro pePasi, chinhambwe chipfupi pane icho cheakawanda geostationary satellite.
Kupfuura uku kwepedyo kunobvumira asteroid kuti ionekwe neziso rakashama kubva kumatunhu akasiyana epasi, kunyanya muEurope, Africa neAsia. Kupenya kwaro kuchafanana nekwenyeredzi hombe 3,3 uye richafamba mudenga usiku nekumhanya kwe. 45.080 km / h. Ichi chiitiko chichave chakakosha pakudzidza kweasteroid, sezvaive zvakaita chenjedzo yekuchengetedzwa kwepasi maererano nemamwe asteroids anogona kumiririra njodzi kuPasi.
Simba rinokwevera pasi richakanganisa zvikuru kutenderera kwaro, richichinja mafambiro aro eramangwana. Kunyangwe kuverenga kwazvino kuchibvisa kukanganisa nePasi mumakumi emakore anotevera, vazivi venyeredzi vanoramba vachidzidza kuti simba rinokwevera pasi rinokwanisa kushandura nzira yaro uye kana izvi zvingamiririra chero njodzi mune ramangwana.
Pane njodzi yekukanganisa muna 2036 kana 2068?
Pakutanga, kuverenga kwakaratidza mukana wekukanganisa kwe 2,7% muna 2029, izvo zvakamutsa kunetseka munharaunda yesainzi. Nekudaro, kunyatso cherechedzwa kwakabvisa njodzi iyi zvachose pazuva iri.
Kana iri 2036 na2068, mikana yekukanganisa yakaderedzwa zvakanyanya. Mukuongorora kwayo kwazvino muna 2021, NASA yakasimbisa kuti Apophis haisi tyisidziro chaiyoiyo kuNyika mumakore 100 anotevera. Uku kuzorodza nzanga yesainzi uye vagari vane hanya nezvekuchengetedzwa kwepasi.
Space mishoni yekudzidza iyo asteroid
Maitiro eApophis asina kujairika kuPasi akakurudzira masangano akati wandei emuchadenga kuronga misheni yekuidzidza zvakadzama. Izvi zvinosanganisira:
- OIRIS-APEX:Ichi chitundumuseremusere cheNASA, chaimbozivikanwa seOSIRIS-REx, chakadzoserwazve mushure mechinangwa chayo kuBennu kunosvika kuApophis. Inotarisirwa kuitenderedza 18 mwedzi mushure mekuita kwayo kwepedyo muna 2029, ichipa ruzivo rwakakosha nezve chimiro uye kuumbwa kwayo.
- dzaRamses:European Space Agency iri kufunga kuparura mishoni yeRAMSES muna 2027, iyo yaizosvika kuApophis isati yasvika kuPasi kuti iongorore maitiro ayo pasi pesimba rinokwevera pasi.
Kukosha kwekudzidza Apophis
Kudzidza kweApophis kunobvumira vanoongorora nyeredzi kuti vanzwisise zviri nani fizikisi yepedyo-Earth asteroids, maitiro avanoita kune. giravhiti yepuraneti uye kuti kukanganiswa kwakadaro kunogona kuita sei panyika yedu. Rudzi urwu rwekutsvagisa rwakakosha mumamiriro ezvinhu apo isu tinogara tichiongorora kuchengetedzwa kwePasi tichitarisana nekutyisidzira kweasteroid.
Rudzi urwu rwetsvagiridzo rwakakosha pakugadzirwa kwemazano e kudzivirira kwepasi, sezvo kana asteroid iri munzira yokudhumhana yaizozivikanwa munguva yemberi, kuva nemashoko chaiwoiwo pamusoro pokuti aya mitumbi yomudenga anoshanda sei kungabetsera kutsausa nzira yazvo.
El kudzidza kwehukuru uye kutenderera kweasteroids seBennu Izvo zvakakosha kuti unzwisise njodzi dzinogoneka dzakabatana. Kubvumbi 13, 2029, richave zuva rakakosha rekuongorora nyeredzi uye chiitiko icho mamirioni avanhu achakwanisa kuona nemaziso. Kubva panguva iyoyo zvichienda mberi, Apophis icharamba iri chinhu chekudzidza uye ichabvumira vanhu kudzidza zvishoma pamusoro pezvakavanzika zvezuva.
