<prompt> Fingqa isihloko: Izigidigidi zezinkanyezi ezisemthaleni wethu zinamaplanethi aphakathi kwelilodwa kuya kwamathathu okungenzeka abe nokuphila kuwo. Izazi zezinkanyezi zafinyelela kulesi siphetho ngemva kokubala amathuba okuba amaplanethi azungeze iGoldilocks zone. Lena ibhande elizungeze inkanyezi lapho izinga lokushisa lilingene khona ukuze amanzi angamanzi agcwale ebusweni beplanethi, futhi kube nokuphila kwamanye amazwe. Lesi sithombe sibonisa indawo ephilayo yezinhlobo ezihlukahlukene zezinkanyezi. Indawo eluhlaza iyindawo yokuhlala HZ, lapho amanzi angamanzi ekhona khona ebusweni beplanethi. Le ndawo ebomvu ishisa kakhulu ukuba amanzi angamanzi abe khona ebusweni beplanethi kanti indawo eluhlaza okwesibhakabhaka ibanda kakhulu ukuba amanzi angamanzi abe khona ebusweni beplanethi. USteffen Kjaer Jacobsen waseNyuvesi yaseCopenhagen wathi: Ngokwezibalo nangezibonakaliso esinazo, ingxenye enkulu yamaplanethi asendaweni yokuhlala izoba amaplanethi aqinile okungenzeka ukuthi anamanzi aketshezi nalapho ukuphila kungase kube khona. Lokhu okutholakele kusekelwe emininingwaneni etholakala kuyi-Kepler space telescope yenhlangano ye-NASA yaseMelika, eye yaqinisekisa ukuba khona kwamaplanethi acishe abe ngu-1 000 azungeza izinkanyezi eMilky Way. Iphinde yathola cishe amanye amaplanethi angaba ngu-3.000. Eziningi zalezi zinkanyezi zinezinhlelo zelanga ezinamaplanethi amabili kuya kwayisithupha, kodwa ososayensi bakholelwa ukuthi kungase kube nezinye ezingakatholakali nguKepler, okulungele kakhulu ukuthola amaplanethi amakhulu emijikelezweni eseduze. Ukuze balinganisele izikhundla zamaplanethi acashile, abacwaningi bavuselela umqondo weminyaka engu-250 owawuyisisekelo sezibalo owawubizwa ngokuthi umthetho kaTitius-Bode. Lesi sithombe sibonisa izinhlelo zezinkanyezi ezingaphandle komhlaba lapho amaplanethi awaziwa ngaphambili ephawulwe ngamachashazi aluhlaza okwesibhakabhaka, kuyilapho amachashazi abomvu ebonisa amaplanethi abikezelwe umthetho kaTitius-Bode ngokwakheka kwezinhlelo zezinkanyezi. Izinhlelo zamaplanethi ezingu - 124 ekuhloleni okusekelwe emininingwaneni evela kusathelayithi i - Kepler, zihambisana nale formula. Lo mthetho, owasikisela ukuba khona kuka - Uranus ngaphambi kokuba ubonwe, uthi kunesilinganiso esithile phakathi kwezikhathi zokujikeleza kwamaplanethi asesimisweni sonozungezilanga. Umthetho kaTitius-Bode wasungulwa cishe ngo-1770 futhi...  <response>: Izazi zezinkanyezi zasebenzisa inguqulo ethuthukisiwe yesilinganiso esineminyaka engu-250 ubudala. Kwasisiza ukuba sibikezele amaplanethi angu - 228 ezimisweni zezinkanyezi ezingu - 151. Bakholelwa ukuthi kuneplanethi eyodwa kuya kwemithathu endaweni yokuhlala ngayinye. Ukwandisa lesi silinganiso kuyo yonke iMilky Way kusho ukuthi kunamazwe amaningi ahlalayo kunalokho obekucatshangwa ngaphambili.
