Iplanethi

UMerkuriyu

Iplanethi encane kakhulu futhi ephakathi kwelanga, ene-orbit yeplanethi enamandla kakhulu.

Iplanethi encane kakhulu, lapho usuku olulodwa kusuka ekuphumeni kwelanga kuya kukuphuma kwelanga luthatha iminyaka emibini ephelele yeMercury.

I-Mercury iyiplanethi eyisihlabathi, enkulu kunaleyo yenyanga yethu. Akunamanzi abandayo, ngakho-ke izinga lokushisa lishintsha phakathi kuka-430 °C ekuseni no-180 °C ebusuku.

Ijikeleza izikhathi ezithathu ngayinye ngemijikelezo emibini enyakatho nentshonalanga yelanga, ngakho usuku olulodwa lwelanga (ukuvuka kwelanga kuya kuvuka kwelanga) luthatha iminyaka emibini yeMercury. Ingxenye enkulu yensimbi iyenza ibe yiplanethi emibili eqinile ngemuva kwe-Earth.

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
