Dombo remuchadenga richauya "pedyo" kuPasi musi waKubvumbi 29. Sezvineiwo, hongu hazvizorove pasi redu. A NASA, sangano reAmerican space agency, rakashuma kuti asteroid yakafona 52768 (1998 IR2) inogona kuva pakati 1.8 uye 4.1 km muhupamhi, ndiko kuti, kuva iye kaviri kureba kwePico da Neblina, mukurusa muBrazil. 5h2p2o
Kubva mune imwe maonero, ihafu yeMount Everest, kana ingangoita chaizvo 5x saizi yeBurj Khalifa, Dubai's skyscraper, ikozvino chivakwa chakareba kudarika chakambovakwa nemunhu. Zita rekuti “1998” rinoratidzawo gore rekutanga kuona munhu ataurwa. Panguva ino, ichafamba nekumhanya kwe 31 miriyoni km/h.
Icho chokwadi ndechekuti pfungwa ye "pedyo" inotemerwa nesangano remuchadenga pakati pedu neasteroid inogonawo kutaridzika seyechokwadi kune chero munhu wepanyika: ichave. 6,3 mamiriyoni emakiromita kubva padyo padyo nePasi. Ndiyo inodarika ka16 chinhambwe chiri pakati pedu neMwedzi.
Iyo asteroid uye zvimwe zvinhu zviri pedyo 14634r
Kunyangwe kureba, ainzi a pedyo neNyika chinhu (NEO), kana kuti “near-Earth object”, mukushandura mahara. KuNASA, chero chinhu chiri mukati me193 miriyoni km kubva pano chinonzi padyo. Kana iwe uchinzwisisa Chirungu uye uchida kuziva nezvemusoro wenyaya, zvakakosha kuti utarise iyo NASA peji pachayo yakatsaurirwa kune zvinhu zviri pedyo.
Pawebhusaiti, pane a área yakatsaurirwa kune zvinhu zvepedyo kusvika nenzira iyi. Imwe yacho, yepedyo (asi kwete saizi ye1998 IR2) ndiyo 2020 DP4, iyo ichapfuura 1,3 miriyoni km kubva pano Svondo rino. Imwezve kure (6,1 miriyoni km) uye idiki, ichapfuura ichi China.
Sezvineiwo kwatiri, hapana chimwe cheizvi zvinhu zvemuchadenga, zvisinei nekuti "zvikuru uye zvine matombo" zvakadii, zvichave nekufamba kwazvo kunoenderana nePasi kwenguva yakareba. Iyo 1998 IR2, semuenzaniso, yatova negwara rayo rinozivikanwa neNASA mukati makore 200 anotevera. Ichaswedera pedyo muna 2079, kakapetwa kana chinhambwe chiri pakati pedu neMwedzi (LD, kana kuti “Lunar Distance”, chiyero chinowanzoshandiswa nesangano remuchadenga kurudzi urwu rwekuronga).
Kusiyana neizvi, kune avhareji yeinenge 30 NEOs vhiki imwe neimwe. CNEOS (Center for Near Earth Object Studies), muzinda unoona nezvekudzidza zvinhu zviri pedyo, inotaura kuti kuchange kuine makumi maviri neshanu kutanga kwaChivabvu - chete izvo zvisingasviki makumi maviri LD kure.
Kana wakasvinura pa 6:56 am musi waApril 29, unogona kuona ndima ye1998 IR2 live, vhidhiyo ye4K yeMwedzi, izvo zvakakodzera kutarisa kunze.
