Adarlian

The second planet of Tauka, Adarlian is an enormous superterrestrial world orbiting well beneath the star's habitable zone. It has an enormous iron core and a great number of other valuable materials to exploit, and is uninhabitable by virtue of its surface temperature, gravity and lack of atmosphere. As such, it is primarily used by the Verdan Federation for resource exploitation. 
== Surroundings ==
Adarlian, due to its proximity to Tauka, cannot sustain a large moon system. However, temporary asteroids captured from Tauka's numerous debris disks and presumably later ejected or destroyed on impact can be found in orbit oftentimes. 
== Physical Characteristics ==
Adarlian is a superterrestrial world, at almost four terrestrial masses. This makes its surface uncomfortable by most sentient life, although there are some species that have elected to establish habitats here. Due to its proximity to Tauka, Adarlian also lacks any consistent atmosphere, as any primordial gases were blasted away by the star's early days. Unlike most planets of this size, Adarlian has an enormous iron core, and this combined with a number of interesting surface features leads scientists to believe that it was once even larger, prior to a massive impact in the system's early history. The debris ejected from the planet's orbit may have formed Adoga, but this is in dispute. 
== Rotation and Orbit ==
Adarlian rotates very slowly, rotating with respect to the background stars once every 23.6 days. Interestingly this makes it one of the few examples of a 1:3 tidal lock, as the planet also orbits its star once every 70.8 days. Why such a mechanism came into being is unclear, but it is certainly much rarer than 1:1 tidal locks, or Moa-like 2:3 ones. 
== Landforms ==
Adarlian's lack of atmosphere and tectonic activity means that most of its surface is as old as the Tauka System that it resides in. The planet is pocked with innumerable craters, as well as a great number of rift formations and impressive cliff faces stretching across much of the planet, left over from when the planet's tectonics were active. Sometimes, the planet's crust has broken open, spilling magma across the surface and leaving great plains of flat igneous rock.
