'IKomesi yeKrisimesi' iyeza. Isibhakabhaka sasebusuku sinokubonakala ngathi siyindawo emileyo, engatshintshiyo, kodwa ngeCawa, nge-16 kaDisemba, i-1,2 yeekhilomitha ububanzi I-comet iya kudlula kwi-12 yezigidi zeekhilomitha ukusuka eMhlabeni . Oko & ampos; malunga nama-30 umgama phakathi koMhlaba nenyanga, kwaye malunga nokusondela njengee-comets, kodwa akukho ndawo ikufutshane ngokwaneleyo ukuba ibe yingozi. Nangona kunjalo, ikwindawo emnandi ukuyenza ibonakale ikhanya kunezona comets zininzi.
Kutshanje inikwe kwi-NASA & apos; s I-Astronomy Picture of the Day , IComet 46P / iWirtanen sele iyeyona comet iqhakazileyo esibhakabhakeni sasebusuku kwaye kuqikelelwa ukuba iyaqaqamba ngokwaneleyo ukuze ibonwe ngeliso lenyama ngexesha leholide. Ii-comets kunqabile ukuba zikhanye ngokwaneleyo ukuba zibonwe ngaphandle kweeteleskopu, ke eli lithuba elinqabileyo lokuwela ii-comets kuluhlu lwakho lwamabhakethi asezulwini.
Yintoni iKomesi yeKrisimesi?
Eyaziwa ngoososayensi njenge-46P / Wirtanen, yiyo le nto kuthiwa yi-comet yexesha elifutshane kuba ingena kwinkqubo yelanga ukujikeleza ilanga rhoqo kwiminyaka emihlanu enesiqingatha. Thelekisa oko neHalley & apos; s Comet, ebonakala kuphela kwinkqubo yelanga yonke iminyaka engama-88. Yaqala ukufunyanwa ngo-1948 sisazi ngeenkwenkwezi saseMelika uCarl Wirtanen e Ukujonga iLick kwiNtaba yeHamilton kufutshane neSan Jose, California, 46P / Wirtanen imalunga nokwenza eyona ndlela ikhanyayo, ikufutshane kule minyaka ingama-20 izayo.
