Ngokutsho koqikelelo, i-asteroid iya kuba nobubanzi beemitha ezingama-914, kwaye ububanzi busuka kwi-440 ukuya kwi-680 yeemitha. igama lakhe - 2001 FO32 - Imbeko yentlonelo ukuba inkqubo yophando Lincoln Near-Earth Asteroid Research (Linear) ngethuba apho ngeenkwenkwezi wavula Ibhanti.
Umzimba wasemazulwini uyadlula emhlabeni ngoMatshi. Isantya sayo siya kuthi phantse i-124 lamawaka eekhilomitha ngeyure. Oku kuphezulu kunesantya apho uninzi lwe-asteroids lubhabha khona. Isizathu sokuqhubela phambili kwe-rapprochement enjalo yinto engaqhelekanga yento engaqhelekanga. Ithathwe ngama-3 angama-3 angama-39 ukuya kwindiza ye-roft yomhlaba.
Ngo-2001 42 ukuya kwiplanethi kumgama omalunga nezigidi ezibini zeekhilomitha. Kungaphaya kwezihlandlo ezihlanu ngaphezu komgama ukuya enyangeni. Kwinqanaba leenkwenkwezi, kuncinci, ke ngo-2001 fo32 fo32 wahlelwa njenge "matroid eyingozi". Nangona kunjalo, akukho songelo lokungqubana kwakhe nomhlaba. "Sifumene i-asteroid kwiminyaka engama-20 eyadlulayo kwaye sifungile kakuhle umkhondo wemimandla yakhe," wongeza i-Paul Shodas, uMlawuli weziko lokufunda into esemhlabeni.
"Intlanganiso" ka-Matshi 21 iya kubonelela nge-lestrononomed ithuba lokufumana uluvo oluchanekileyo ngakumbi lobume be-asteroid kunye ne-albeno yayo. Kwaye uyayazi kwakhona ukwenziwa kwayo. Ngokukodwa, ukufundisisa i-spectrum yokukhanya eboniswa kumphezulu we-asteroid, izazi ngeenkwenkwezi ziya kulinganisa "impahla" ye chemistry yezimbiwa.
Izifundo zifuna ukuziqhuba ngoncedo lwe-telescope ye-3.2 ye-meter ye-Inrared ekwibanga lesiqithi sase-Kaiau-Kea kunye ne-spex ekhutshiwe. "Ngoku kukho incinci malunga nendawo, kwaye ndiyabulela ngayo kwindlela yayo, sinokufunda into entsha," utshilo uLance Benner, isayensi kwilebhu esebenzayo ye-NASA.
I-Arhente ikwacebisa nge-astronomers yabathandi bokuqhuba ngokwabo. Ke, uPaul Chodas uthe i-asteroid izakuba yeyona nto imbi kakhulu xa iqhuba kumazantsi. Unethemba lokuba abathandi baya kuba nakho ukubungqina le nto. "I-Amateur Asstronomers kwi-hemisphere esemazantsi iya kuba nakho ukubona i-asteroid ngokuhlwa ngaphambi kokuba kwenziwe i-rappidhement ekufutshane. Kodwa koku kuyakufuna iteleskopu ephakathi kunye nomngxunya we-intshi ezisibhozo, kunye nemephu, "i-chodas ishwankathe.
