Iplanethi eseduze nelanga kanye nencane kakhulu iyadingeka. Impendulo iyadingeka.?
ukukhetha okukodwa.
Iplanethi eseduze nelanga yiMercury.
I-Mercury ithathwa njengeplanethi encane kunazo zonke eplanethini sonozungezilanga, enobubanzi obungamakhilomitha angaba ngu-4,879 kuphela, ithi incane kuneNyanga.
I-Mercury izungeza iLanga emzileni wezinsuku ezingama-88 woMhlaba, okusho ukuthi ingaqeda ukuzungeza iLanga izikhathi ezine ngonyaka.
Izimo zeMercury zinzima ngokwedlulele, njengoba izinga lokushisa lishintsha kakhulu phakathi kwemini nobusuku, kanti izinga lokushisa lamanzi phakathi nosuku lifinyelela cishe ku-430°C futhi lehle lifinyelele cishe ku-180°C ebusuku.
Ngaphezu kwalokho, iplanethi inomkhathi omncane, owuchaya emisebeni yelanga enamandla nemangalisayo.
Ngakho-ke, i-Mercury imele isifundo esithakazelisayo sososayensi basemkhathini kanye nokuhlola amaplanethi.
