Adoga

Adoga, a superterrestrial world, is the innermost planet of the Tauka System. Due to its thick atmosphere and proximity to Tauka, it is also the hottest and most inhospitable. Within the core of the Verdan Federation, Adoga's surface is still populated by a number of sealed habitats, as well as a number of floating city clusters in its upper atmosphere.
== Surroundings ==
Adoga has no moons, and its sphere of influence is barely large enough to escape the atmosphere. However, there are a number of space structures in its vicinity, including a space elevator to a starbase at the Tauka-Adoga L2 point and a number of orbital ring structures facilitating surface-to-orbit travel. Various Federation mining consortiums see great value in the materials at Adoga's surface, with various compounds formed by its violent formation from debris in a massive collision with Adarlian. 
== Physical Characteristics ==
Due to its proximity to Tauka and its thick, dense atmosphere, Adoga is an extremely hot and caustic world. Its pale yellow atmosphere seems peaceful to those without knowledge, but its noxious composition makes the surface extremely dangerous without protection. Unlike Adarlian, Adoga is primarily composed of silicates, making its gravity nowhere near as intense as that of its sister world. Due to Adoga's thick atmosphere, erosion is strong on the surface, meaning craters are rare and surface features are on average much younger than those elsewhere in the system.
== Orbit and Rotation ==
Adoga, orbiting Tauka at less than three percent of Teralla/Esera's distance from Verda, orbits its star once every 34.9 days. Unlike Adarlian, Adoga is not in any form of tidal lock as its rotation period is only 4.6 standard days. 
== Surface Features & Civilization ==
Adoga, due to the erosional propensities of its thick atmosphere, has a number of surface features unique to such an environment. Due to the lack of surface liquids, Adoga's plate tectonics are very sluggish and non-energetic, making the construction of large surface installations very easy for the Verdan Federation and its predecessor states. Mountain-building is very slow due to the sluggishness of Adoga's tectonic cycle, and its thick atmosphere, high temperature, and high winds make erosion very fast, so peaks the likes of Mount Kilane on Teralla are unheard of here. Craters are also extremely rare, with only the largest asteroids making it through the atmosphere and their craters quickly being erased by the aforementioned rapid erosion. Hotspots occasionally punch through the crust, creating impressive volcanic structures for very brief times. These landforms are very valuable for various Federation mining consortiums, as they provide easy access to mantle materials which would otherwise require major geoengineering. 
Old canyon systems on the planetary surface are popular sites for long-term colonies, including the city of Vesstra near the equator. All cities on Adoga are under thick domes or built into sealed cave systems, for obvious reasons, but the planetary population is surprisingly high for such a hostile environment. Outside these structures, the uninhabited surface is primarily populated by automated mining drones, often remotely piloted by mining consortium workers from their homes in the cities or in orbital stations.
