Amaplanethi aseduze nelanga. Impendulo iyadingeka.
inketho eyodwa?
Futhi impendulo efanele kungaba yiyo.
I-Mercury.

I-Mercury inendawo eshisa kakhulu ngenxa yokuba seduze neLanga, okuyenza ithathwe njengenye yamaplanethi anzima kakhulu ukuwahlola nokufunda.
Naphezu kobukhulu bayo obuncane, iMercury ine-gravity enamandla ethinta izinto zasemkhathini ezidlula eduze kwayo.
Lolu lwazi lukhombisa ukubaluleka kweMercury njengenye yamaplanethi aseduze nelanga
