Ina

Ina is the 4th planet, counting outwards, in the Vaia system. It's on the very edge of the habitable zone at 1.3 AU from the sun and holds the only life in the system, which is glacian in nature, notably the Icians.

History
The planet were created about 4 billion years ago, at the same time as Vaia, from the cosmic dust disk being left over from the star formation. During the first billion years the small planet (Which later would become the core.) gathered more and more water until it contained the current levels of water about 3 billion years ago. It then stayed liquid for 2 billion additional years until it slowly started to freeze 1 billion years ago.

Physical features
Ina is slightly tilted at ~9 degrees and therefore have very weak seasons, although small variations in seasons do exist - which the local life have adapted to. The surface is covered almost completely in ice, with the exception of the equatorial and seasonal lake of Atevine, which can cover up to 300.000 m² in area during the latest parts of the summer, and rivers spreading outwards from the equator. The ice sheet extends for about 10km, although local hotspots where water pours out onto (or right below) the ground is scattered across the planet. Below the ice is a large ocean which extends for hundreds of kilometres. It's unknown whether this ocean holds life or not, but is a strong possibility due to the world being unfrozen for 2 billion years. The core is rocky and mostly consists of oxygen-iron molecules. A day on Ina lasts for 16 hours.

Ina has no moons.

Climate
The climate of Ina is very cold and frozen and usually below zero degrees. Local hotspots near the equator where the temperature can reach up to 10 degrees at the equator during the summer. The temperature at the equator is usually around -5 to -10 degrees while the poles reaches -100 to -200 degrees and sometimes these temperatures migrate from the poles towards the equator (Although seldom reaches it.) causing Cold Storms which devastates most unprotected life in its path. Blizzards often ravage the planet, both locally, regionally and planetary - although it's unusual for planetary ones. During blizzards it's usually not snow falling from the sky and instead it's hail - storming at 50 m/s winds.

Due to the unusually large amount of gas giants in the Vaia system there is an similarly large amount of asteroids in the system causing a relative massive amount of asteroid crashes on the planet. Randomly and recurring the planet can be subject to asteroid storms which covers one side of the planet in constant asteroid fire for days or even weeks causing mayhem amongst the local wildlife and appearance of temporary oceans.
