Iplanethi

Neptune

Iplanethi ekufuphi kakhulu, umkhenkce onamandla amakhulu onezimoya ezikhawulezayo ezilinganisa kwinkqubo yelanga.

Iplanethi efunyenwe ngepensile phambi kokuba iboneke kwiteleskopu, nekhaya lemimoya ekhawulezayo eyaziwayo kuyo nayiphi na iplanethi.

I-Neptune ifana ngobungakanani kunye nokwenziwa kwe-Uranus kodwa inkulu kwaye inesisindo esininzi. Iimoya kwimozulu zifike malunga ne-2,000 km/h.

Yaye yeyona planethi yokuqala efunyenwe ngobuxoki be-matematic: ukungalingani kwintshukumo ye-Uranus yabangela ukuba uUrbain Le Verrier a kalkule indawo yayo, kwaye uJohann Galle wafumana loo nto ngo-1846. Inyanga yayo enkulu, iTriton, ijikeleza ezantsi kwaye mhlawumbi yinto ethathwe kwi-Kuiper belt.
