Iplanethi

UVenusi

Ikhaya leplanethi, elifana ngobukhulu, lifakwe empilweni ye-carbon dioxide.

Iplanethi efana ne-Earth, futhi iyiplanethi eshushu kakhulu kuhlelo lwelanga.

I-Venus ifana kakhulu neplanethi yethu emhlabeni ngobukhulu nesisindo, kodwa inhlabathi yayo eqinile ye-carbon dioxide yenza imiphumela yokufudumeza. I-pressure yendawo ilingana nezinga lezulu izikhathi ezingu-92 futhi izinga lokushisa lilingana ne-464 °C, elibanda kakhulu kunaleli leMercury.

Ijikeleza emuva (i-retrograde) futhi ngokucophelela: ushintsho olulodwa luthatha amahora angama-243 eplanethi, ngaphezu konyaka wayo wezinsuku ezingama-225. Uma ibonakala kusuka eMhlabeni, iyinto ekhanya kakhulu emkhathini wemini ngemuva kwenyanga.
