INkanyezi into eyimbulunga enkulu, eyakhiwe ikakhulukazi ngeHwanzi (Hydrogen) kanti futhi evuthayo ebanjwe umNyondo ukuze ihlale iyimbulunga. Inkanyezi ekuyiyona esondele kuthina nomhlaba wethu ileyo esiyibiza ngeLanga. Into edala ukuthi ezinye izinkanyezi zibonakale zincane kuneLanga kubangelwa ibanga elimaphakathi kwaNomkhubulwane kanye nazo lezo zinkanyezi. Izinkanyezi ekuyizona ezigqame kakhulu kunezinye ilezo eziqoqelene ezakha iziShomo, noma iziNyonta, kanye nezinye iziNkanyezi ezikhanya ukudlula ezinye eziqanjwe amagama thizeni. iziMfundindalo zomkhathi sezihlanganise uqukethomagama leziNkanyezi esizaziyo kanye namagama abavumelana ngawo umhlaba jikelele. Kulokho amehlo ethu akwazi ukukubona kanye nolwazi oseluqoqwe imishini, kukhombisa ukuthi umKhathilibe ungase ube nezinkanyezi ezilinganiselwe kwisi- 10 22 {\displaystyle 10^{22}} kuya kwisi- 10 24 {\displaystyle 10^{24}} , kanti iningi lalezi azibonakali ngamehlo nje. Ukuzalwa kwenkanyezi kuqala ngemfingqomNyanda yefulomoya elakhiwe ngeHwanzi, kanye nenani elincane lezinye izakhi. Isisindo seNkanyezi ilonanqoba elikhetha ushintshoshintso kanye nendlela ezofa ngayo leyoNkanyezi. Empilweni yayo, iNkanyezi iqhakaza ngokukuhlanganiswa kweHwanzi ukuthi kwakhiwe iHwelanga kumsuka wayo, okukhiqiza imPekumpeku ehamba ingaphakathi leNkanyezi kuze kube ifinyelela ebusweni bayo, nokuyilapho ikhafulelwa emKhathini.
