In this picture you see a Venus in orbit. Of which it is surrounded by its atmoshere composed mostly of carbon dioxide. Venus' temperature is about 457C degrees. On its surface it 730k. Enough to mealt lead.
Its surface is made up of volcanoes, craters, and mountains of lava. The reason Venus is so hot is because its atmosphere traps small amonts of energy from the sun that reaches the surface along with the heat the planet itself releases.
As seen in the picture, the planet has no rings and no moons.
