<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: I-Passage: I-Gliese 436 b yatholakala ngo-August 2004 ngu-R. Paul Butler noGeoffrey Marcy baseCarnegie Institute of Washington nase-University of California, eBerkeley, ngokulandelana, besebenzisa indlela yejubane le-radial. Kanye no-55 Cancri e, kwakuwokuqala kwesigaba esisha samaplanethi anesisindo esincane M sini esifana neNeptune. Iplanethi yaqoshwa ukuthi idlule inkanyezi yayo ngenqubo ezenzakalelayo e-NMSU ngoJanuwari 11, 2005, kodwa lo mcimbi awuzange unakwe ngaleso sikhathi. Ngo-2007, uGillon wahola ithimba elalibheke ukudlula, lidlula kuyi-stellar disk uma liqhathaniswa neZwe. Ukubonwa kokudlula kwaholela ekutheni kutholakale isisindo sayo esiqondile nomoya wayo, zombili ezifana kakhulu nalezo zeNeptune, okwenza iGliese 436 b ngaleso sikhathi ibe yiplanethi encane kunazo zonke eyaziwayo edlula ngaphandle kwelanga. Leliplanethi likhulu ngamamayela ayizinkulungwane ezine ngobubanzi kune - Uranus futhi likhulu ngamamayela ayizinkulungwane ezinhlanu kuneNeptune futhi linamandla kancane. I-Gliese 436b ihamba ibanga elingamakhilomitha ayizigidi ezine noma ingxenye eyodwa kwezingu - 15 zesilinganiso sobude bukaMercury ukusuka elangeni. Umbuzo: UGilese 436 b watholakala nini?  <response>: Agasti 2004
