Phakathi kweplanethi, bese i-asteroid, manje iplanethi encane: I-Ceres ishintshe incazelo kaningi kunanoma iyiphi enye izwe.
I-Ceres yatholakelwa nguGiuseppe Piazzi ngo-1801 futhi yaqala ukubhekwa njengeplanethi, bese iyisibhakabhaka, futhi kusukela ngo-2006 iyiplanethi encane. Kuyinto encane kakhulu injongo e belt.
NASAI-Dawn spacecraft ijikeleze iCeres kusukela ngo-2015 kuya ku-2018 futhi yathola izitshalo ezikhanyayo zezinhlayiyana eOccator crater, isivivinyo se-briny water ngaphansi kwesikhumba.

Amathuluzi nama-lessons asebenzisa amamodeli alula ukufundela kuphela. Akufanele asetshenziswa ukuhlola, ukuhlela umsebenzi noma noma yiluphi ukhetho lokusebenzela. Izitifiketi zimahhala futhi aziqinisekisiwe. Funda isichazamazwi sezinto ezifundiswayo
