Oumuamua 2.0, chinthu chachiwiri cha ma interstellar chikadatha kulowa mu Solar System
Gulu la zakuthambo likusangalala ndi chinthu china chotsogola, chomwe chingakhale chachiwiri kupezeka, mwina chinafikira kupitirira dongosolo lathu la dzuwa.
Gennady Borisov ndi wokonda kuchita zakuthambo, akanatha kudziwa comet pa Ogasiti 30, pogwiritsa ntchito telescope yomwe adadzipangira yekha, ndipo asayansi akhala ofunitsitsa kudziwa zambiri za C / 2019 Q4 (Borisov).
Mu Okutobala 2017, chinthu chokha chidapezeka pamtunda wa 30 miliyoni km kuchokera ku Earth chomwe, chifukwa cha kutchuka kwake komanso kuthamangitsidwa kwake kosagwirizana ndi kukopa kwa Dzuwa, adadziwika kuti ndi woyamba kubisalira ndipo adatchedwa Oumuamua wolemba zakuthambo waku Canada Robert Weryk yemwe ankagwira ntchito ku Institute of Astronomy ku University of Hawaii.
Makhalidwe a chinthucho.
Makhalidwe a comet wachiwiri wotchedwa C / 2019 Q4 (Borisov), ndi osiyana ndi mawonekedwe oyamba; adawulula kale kuti njirayo ili ndi mawonekedwe a hyperbolic (kutanthauza kuti siyigwidwa ndi mphamvu ya Dzuwa), m'malo mozungulira mawonekedwe a elliptical omwe amatsimikizira kuzungulira kwa zinthu zomwe zikuzungulira Dzuwa. Njirayo ikuwonetsa kuti astro pamapeto pake udzadutsa makina ozungulira dzuwa, osabwereranso.
Woyamba kugwedezeka kwamanyazi wayesedwa kale!
Pakadali pano gulu la akatswiri a zakuthambo anena kuti C / 2019 Q4 ndi yayikulu kwambiri, yayikulu kwambiri kuposa Oumuamua. Mukudziwa kale kuti ndichisanu, chomwe chimatanthauza kuti ndi chowala bwino ndipo chidzawala kwambiri pamene likuyandikira Dzuwa kapena likusintha molimba kuchokera ku cholimba kupita ku mpweya.
Pakadali pano chinthu chaposachedwa cham'mlengalenga chikuwonekera kumwamba; pamalo otsika dzuwa lisanatuluke, motero kumakhala kovuta kulizindikira.
