Umwaka ushize, abahanga mu bumenyi bw'ikirere bavumbuye ibihumbi n'ibihumbi batazwi hafi y'Isi - Asteroide y'isi, ni inyandiko y'ibihe byose byo kwitegereza. Ibi bivugwa mu kinyamakuru Kamere.
Muri esheshatu ya 2021, Asteroid Apofis yegereye isi intera ya hafi mu myaka umunani. Umwanya "amabuye" hamwe na diameter ya metero 340 yagurutse na km miliyoni 16 uvuye ku isi yacu, ifatwa nkintera itekanye.
Muri 2029, Apofis yongeye kugaruka, iki gihe inama ye isi ntizagira ingaruka ku isi imyaka 30-40 ifatwa ku isi hose kandi izaba ifatwa ku mubumbe wa geostatie. . Umushyitsi wamabuye arashobora kuboneka nijisho ryambaye ubusa. Abahanga mu bumenyi bw'ikirere bwa mbere mu mateka ya none bazashobora kwizihiza asteroid nini hafi.
Kurinda umubumbe
Ikibanza cya Asteroid apofis mu cyumweru gishize yahaye abahanga amahirwe meza yo kugerageza sisitemu yo kuburira ibibazo biteye akaga mumwanya wa hafi. Hamwe na telesikope idasanzwe, abahanga mu bice bitandukanye by'isi ikurikirana ikirere nijoro no gukurikirana ibintu biri hafi byerekana akaga gashobora kuba umubumbe w'isi. Kugerageza kwitegereza Apofis byerekanaga ko amakipe yo mu bumenyi bw'ikirere, mu gice icyo ari cyo cyose cy'isi atari cyo, ashobora gufatanya kugira ngo ashimaze iterabwoba riva mu "mabuye" ya cosmicro.Shakisha Asteroide
Ibigo byose bya Aerospace byisi bifite sisitemu zabo kugirango intego zibeho ziteje akaga mumwanya wa hafi. Kurugero, NASA ikoresha sisitemu nkiyi yo gushakisha hafi-yisi asteroide no gusuzuma iterabwoba ryabo kuva 1998. Muri icyo gihe, abakozi b'ikigo bavumbuye ibintu 25.000. Mugihe imiterere yandika, umwaka ushize wabaye inyandiko yo gufungura. Nubwo Covise, icyorezo cyabereye, cyagize ingaruka ku murimo w'abahanga benshi, abahanga mu bumenyi bw'ikirere basanze bakazanwa muri kataloge ya 2958 batamenyekanye hafi y'isi.
Abarenga kimwe cya kabiri cy'izi nzego bashoboye kumenyeshwa hamwe n'ubushakashatsi bwa SKLIME - Telesikopi eshatu ziherereye muri Arizona. Telesikopi zashoboye kumenya ndetse na asteroid yuzuye 2020 cd3, diameter yo munsi ya metero 3, yakoresheje uburemere bwisi. Inyenyeri yigihe gito yisi yangije ingoyi nini kandi igava muri geocentric orbit muri Mata umwaka ushize. Inyenyeri nziza cyane 2020 CD3 - 32m, albedo - 0.1-0.6.

Ikindi cyiciro cya hafi-yisi Asteroide - 1152 ikintu, cyafunguye sisitemu ya Palescope ya Pan-Star muri Hawaii. Mu matsiko yabonetse - 2020 rero, utari absteroid, ariko igice cyishami ryihuta "Centaur" by'Ubushakashatsi 2 Poptaratus, yatangijwe mu kirere mu 1966.
Asteroide zimwe
Bimwe mubintu byisi biri hafi yabonetse muri 2020 byageze hasi kure cyane. Nibura 107 muribo banyuze kuri iyi si yaturutse kure, bikaba bitarenze kure kugeza kukwezi.
Kurugero, muri Kanama, Asteroid 2020 QG yagurutse Km 2950 hejuru yinyanja y'Ubuhinde. Kandi nyuma y'amezi atatu, ikindi kintu gito gifite diameter ya metero 5-10 - 2020 vt4, yatsinze km 345 gusa ku isi, iri munsi y'isi itangira. Amashusho yambere yabonetse amasaha 15 gusa nyuma yo kuba hafi yumubumbe wacu. Niba yinjiye ahantu hakomeye k'ikirere, birashoboka rero ko bishoboka, byari gutandukana.
