Irke is the 3rd planet in the Kelnis System and, although not inside the habitable zone of Kelnis, it supports a stable ocean of liquid water.

In-game Description

"Irke is the third planet in the Kelnis System, and one of the more hospitable worlds for kerbal colonization. The planet is covered in a deep ocean of liquid water. As a result, many kerbal scientists believe that there could be complex ecosystems, similar to Aquel. Others think that Irke may be too hot for life to exist in the oceans. The only way to find out is by going there yourself!"

Physical Characteristics

Irke is an ocean world skirting the edge of Kelnis's habitable zone. Despite that, Irke hosts a deep ocean on the surface, similarly to Aquel. The ocean covers the entire planet, even where light isn't received. This is because of the strong ocean and wind currents allowing heat to transfer easily across the planet.

Atmosphere

Because it remains out of the habitable zone of Kelnis, Irke has lost a lot of its atmosphere over time. Right now, the planet has an atmospheric pressure of roughly 16 Pa, just under 3 times as dense as Duna's. Most of the gases that have remained on the surface have a high density, and because of this Irke's atmosphere is somewhat unbreathable for kerbals.

The atmosphere of Irke is made mostly of carbon dioxide (CO₂), but in lower altitudes scientists have noted large amounts of sulphur hexaflouride (SF₆). As a result, kerbals that could breathe the air would have deeper voices.

Possibilities of Life

Irke has a stable ocean of liquid water on the surface and a relatively dense atmosphere. Because of this, it is possible for extremophile forms of life to exist in its sea.

Another indicator for the possibility of life could be the geothermal vents on the seafloor of Irke. These vents would be constantly heated by subsurface activity, and would be rich in chemicals for life.

Trivia

  • Because of Irke's proximity to Kelnis and humid atmosphere, it has a large storm forming on the substellar point in spite of its ocean currents.
