Gungava

Gungava is a planet in the Pallavi System within the Elysian Sigma.
Gungava is roughly twice the size of Earth and has a very feint atmosphere. 
It's not an invasive atmosphere, but nor is it breathable and in most other aspects (excepting breathing) it's close to hospitable - but the world has no natural water sources. It's home to a very large dome colony, but it's off limits to visitors. It's possible to walk outside without a protective suit, but long term exposure to eyes and other regions of the body where the atmosphere can make direct contact with sensitive areas, can cause irritation. A mask must be worn at all times to breathe. 
The soil of Gungava has practically no minerals and is extremely rocky, excepting a meters deep layer of clay on the surface, making it incredibly poor for farming. 
The temperature on Gungava is very low, despite being the closest to the sun. Artificial heating is necessary within the domes to support life and the warmest time of year the temperature reaches 2 degrees Celcius, but rarely goes above sub-zero.
