A planet with a massive metal core, rocky, with a diameter almost as large as the Earth, yet the mass is slightly higher. Gravity is close to Earth's, or even slightly higher. It revolves around its red sun in 58 hours, but it turns to it with one side and there will be no change of day, at least on the surface. Since it has the metal core, it has the magnetic field. 

 The atmosphere is dense, tens of Earth's atmospheres (on Venus ~ 92 atm.). The composition is mainly carbon dioxide, nitrogen, sulfur oxides, sulfuric acid, as well as hydrogen sulfide, mercaptans (RSH), dimethyl sulfide, perhaps a bit of nitrogen oxides, there is practically no water. 

Surface temperature fluctuates between 320 C and 405 C in the central regions of the illuminated and dark hemispheres of the planet, respectively. In the area of the terminator, the temperature is about 365 C. A few kilometers above the surface, the temperature levels off due to strong winds, and also gradually decreases. Most of the life forms are concentrated in cloud layers at an altitude of 40 to 55 km. In the upper part of this layer, the pressure and temperature are close to Earth's. There are two variants of biochemistry with solvents in the form of dimethyl sulfide or sulfuric acid. Some organisms can switch from one to another. Flying organisms with sulfuric acid can sometimes descend (dive) into the lower atmosphere. The melting and boiling points of demytyl sulfoxide {(CH3) 2SO} 18C and 189C, respectively, and sulfuric acid (H2SO4) 10.4 C and 337 C. 

To explore the hottest regions of the daytime zone, as well as tectonic faults and areas of long-term volcanic activity, the intelligent creatures created bioforms (biorobots) with liquid sulfur as a solvent (melting point 112.85, boiling point 445 C). These creatures are used to extract valuable mineral resources from the planet's surface.

 The planet has strong, hot winds blowing almost all the time round its surface. 

It revolves around the sun in 5 Earth years. Since it has the metal core, it has the magnetic field yet very weak. 

 Life is based on carbon akin to the Earth-like, so there are huge plants living close to the rocks and adapted to minimum water supply. They have the metabolism close to the Earth deserts plants, yet they can move using their root-like expansions to the places where water may spring from underneath. Features called recurring slope lineae may have spurts of briny water flowing on the surface, but this evidence is disputed; some scientists argue the hydrogen spotted from orbit in this region may instead indicate briny salts. 

 The intelligent life exists below the surface where the beautiful vaults and underwater oceans are.
