Sekureva kwekufanotaura, iyo esteroid ichave neyakajaira mita anenge 914, uye upamhi hunobva kune 440 kusvika mazana matanhatu nemakumi matanhatu emamita. Zita rake - 2001 Fo2 - Treves dzekuremekedza chirongwa chekutsvagisa Lincoln padhuze ne-Earth Asteroid Research (mutsara) panguva iyo vazukuru uye vakavhura arishiro.
Muviri wekudenga uchapfuura nepasi mukupera kwaKurume. Kumhanya kwayo kunenge kuri kuita zviuru gumi nezvisere makiromita pane awa. Izvi zvakakwira kupfuura kumhanya kubva kune iyo inonyanya kuongorora nhunzi. Chikonzero chekukurumidza kuputika marapirwo chiratidzo chisina kujairika chechinhu ichi chiratidzo chinhu. Iyo inosungirirwa pamadhora makumi matatu nemashanu kune ndege yenyika yePasi kana
2001 fo32 inoswedera kupuraneti kwenguva inokwana kwemamiriyoni maviri emamiriyoni. Iyo kakapetwa kashanu kupfuura chinhambwe kuenda kumwedzi. Muchiyero chechiratidzo, zvishoma, saka 2001 Fo2 Fo2 yakange yakadzingwa se "inogona kuva nenjodzi". Nekudaro, hapana kutyisidzirwa kwekurovera kwake pasi pano. "Takawana ongorora makore makumi maviri apfuura uye takadzidza chaizvo trajector ake akapoterera zuva," akawedzera Paul Chodas, Director wenzvimbo yekufunda chinhu chepakutanga.
"Musangano" Kurume 21 uchapa hunyanzvi mukana wekugamuchira imwe pfungwa yakarurama yehukuru hweseteroid uye albedo yayo. Uye zvakare ziva huwandu hwayo hwakatangira. Kunyanya, kudzidza mabvi wechiedza kunoratidzwa kubva pamusoro peiyo asteroid, vazivi venyeredzi vari kuzoyera "kuiswa" kwemakemikari emaminerari.
Zvidzidzo zvinotsigira kuitisa nerubatsiro rwe 3.2-meter infrared tescope inowanikwa pamusoro peiyo Island Island yeManau-Kea uye iyo Spex Infrared Spectrograph. "Zvino pane zvishoma nezve nzvimbo yacho, uye nekutenda kune chimwe chinhu chitsva," akadaro Lance Benner, musayendisiti kubva kuNASA Laboratori.
Iyo agency inoratidzawo kuti vadikani vevanoda kuitisa vatsvage vega. Saka, Paul Chodas akataura kuti esteroid ichave iri chinhu chinoshamisa kwazvo paunenge uchityaira kuburikidza nedenga rekumaodzanyemba. Anotarisira kuti vadikani vanozokwanisa kupupurira ichi chiitiko. "Amateur vazivi venyeredzi vekumaodzanyemba hemisphere vanozogona kuona esteroid manheru pamberi penzira yepedyo. Asi nekuda kweichi ivo vachada sedhiti-shuwa teresikopu ine gomba remasere masere masendimita, pamwe nemepu, "Chodas yakapfupikiswa.
