Chaka chatha, zakuthambo zidapeza zaka zambiri zakuda zomwe sizinadziwike kale - zomwe zimajambulidwa nthawi zonse zokopa. Izi zikunenedwa mu magazini yachikhalidwe.
M'chisanu ndi chimodzi mwa Marichi 2021, arteid opepi adayandikira padziko lapansi patali kwambiri zaka zisanu ndi zitatu. Space "miyala" yokhala ndi mainteni 340 owuluka ndi ma km 16 miliyoni kuchokera ku pulaneti lathuli, lomwe limawonedwa kuti ndi mtunda wotetezeka.
Mu 2029, apoPhis abweranso, nthawi ino msonkhano wapansi pa dziko lapansi sudzakhala wopanda vuto: Asteroid udzathera dziko la 30- 40id . Mwezi wamwala ukhoza kuwoneka ndi wamaliseche. Akatswiri azakuthambo kwa nthawi yoyamba mu mbiri yamakono adzaona Astherid wamkulu kwambiri.
Chitetezo cha mapulaneti
The Span ya ASTERIS sabata yatha idathandizira asayansi mwayi wabwino kuyesa njira yochenjeza za nthawi yoopsa. Ndi ma telesikopu apadera, asayansi ochokera kumadera osiyanasiyana padziko lapansi amayang'anira nyenyezi usiku ndikutsata zinthu zapadziko lapansi zomwe zikuyimira ngozi zomwe zingachitike padziko lapansi. Kuyesera kuwona apope awonetsa kuti akatswiri azakuthambo awonetsa kuti akatswiri azakuthambo achitapo kanthu, kulikonse komwe sikungagwire ntchito limodzi kuti muchepetse kufalikira kwa "miyala" yochokera ku Cosmic "miyala.Sakani a ASTERIDS
Mabungwe onse onse a Awesseace padziko lapansi ali ndi njira zawo zokha zochenjeza za zochitika zowopsa mu malo opanda kanthu. Mwachitsanzo, NASA imagwiritsa ntchito njira zotere kuti azisaka pafupi ndi ma asteroiles pafupi ndi kuwopseza chiwopsezo chawo kuyambira mu 1998. Munthawi imeneyi, antchito a bungweli adapeza zinthu 25,000. Monga chilengedwe chimalemba, chaka chatha chakhala cholembedwa. Ngakhale anali ndi zaka zapakati pa Coviid.
Zoposa theka la matepi awa adatha kuwona ndi Catalina Sky Support - ma telescopes atatu omwe ali ku Arizona. Ma telescopes adatha kudziwa ngakhale 2020 cd3, m'mimba mwa mita 3, yomwe idagwira mphamvu yokoka yapadziko lapansi. Satellite wakanthawi wa dziko lapansi adawononga zingwe za mphamvu yokoka ndikuchoka ku Geocentric Trabit mu Epulo chaka chatha. Mtheradi wamkulu wa nyenyezi 2020 CD3 - 32M, Albedo - 0.1-0.6.

Chingwe china cha Asteroids pafupi ndi dziko lapansi - 1152, adatsegula pofika poto. Pakati pa zomwe mukufuna kudziwa - 2020 Ndiye, zomwe sizinali gawo la othamanga "Celeurus" wofufuza mawu 2 Appratos, adayamba kukhala malo mu 1966.
Ena asteroids
Ena mwa zinthu zapadziko lapansi pafupi ndi 2020 adafika panthaka pachitunda choyandikira kwambiri. Osachepera 107 a iwo adadutsa ndi pulaneti lathu patali, chomwe chimakhala chocheperako kuposa mwezi.
Mwachitsanzo, mu Ogasiti, asteroid 2020 Qg adangotuluka 2950 km ku Indian Ocean. Ndipo patatha miyezi itatu, chinthu china chaching'ono chokhala ndi mainchesi 5-10 - 2020 vt4, ndi ma km okhaokha ochokera pansi pano, omwe ali pansi pa gawo lozungulira. Zithunzi zoyambirira zidapezeka maola 15 zokha atakhala pafupi ndi dziko lathuli. Ngati atalowa zigawo za mlengalenga, ndiye kuti mwina, zingatheke.
