A rocky terrestrial planet with a runaway greenhouse atmosphere.

Sagan II has a thick, impenetrable atmosphere, dominated by carbon dioxide and sulphurous materials. Sulphuric acid clouds churn away in the turbulent atmosphere, creating huge frictional forces that are released as powerful lightening storms. These clouds condense to form acid rain, which evaporates before it can reach the surface.

Chains of dome volcanoes reaching up to 10km high and 300km long meld into each other to form long volcanic plains and valleys. Pouring out enormous amounts of carbon dioxide and sulphurous materials. Lava flows from these have created huge lava oceans that are regularly replenished. The cooling lava approaching solidification is quickly eroded away by acid rainfall that helps to form long tentacled channels, conduits for fresh lava flows. Large columnated structures are carved out by the very dense atmospheric winds. These form canyon like regions as well as intricate features that look like abstract architectural sculptures that pop in and out of existence under the accelerated weathering conditions of Sagan II.

Sagan II is much more closer to its sun than Venus thus experiences an even more heightened greenhouse effect. Surface temperatures sore from a minimum of 382K (109 C) to a maximum of 832K (558 C). It has a large axis tilt of 34 degrees causing more temperature fluctuations. It's high orbital and rotation speeds of 49.2 and 410.5Km/s further add to its tumultuous climate.
