Izotz (RS 8411-6-6-176877-3 A8.1 in Beta Patch 8) is a frozen I-Class world and is the only moon of Kalder. It is located in the Calida system in the Small Magellanic Cloud.

Izotz has a diameter of 6748.656 kilometers (52.906% the diameter of Earth), and the average surface gravity is 0.2612 G's. In comparison to its parent, this is quite large. It orbits Kalder every 179.617 days and rotates every thirty-five hours and thirty-one minutes.



An intricate system of ridges possibly created by an underground ocean.

Izotz is covered in a thick layer of ice. Like Kalder's glaciers, this ice is made from frozen hydrocarbons.


One of the largest craters on Izotz, estimating at a hundred kilometers in diameter. Note the hill in the center.

The surface is broken by dark brown ridges that extend less than a kilometer above ground level. Since Europa appeared very similarly before its terraforming, it is suggested that an ocean may exist below the ice of Izotz. If this were true, then signals of life have yet to be discovered.

Izotz is pocketed with craters large and small. These craters range from a few hundred meters to several dozen kilometers across. The craters' smoothness and sparseness further suggests an ocean has been constantly rebuilding and flattening the surface of Izotz through hidden channels that liquid would run up and freeze in.


A patch of canyons.

Interestingly, small canyons have formed on Izotz. While their exact cause is unknown, there could be a tectonic system of continents floating on top of the possible ocean. As tectonic plates would separate, liquid would fill in the spaces and freeze, creating an indent that would be the canyons. Seeing how there are no mountains, however, this idea has yet to be accepted entirely.


The climate of Izotz is very regular. Normally the surface of Izotz is -325 degrees Celsius, but as it is with Kalder, the temperature only fluctuates by a few degrees as the planet goes through its year. Unlike it, though, Izotz has no greenhouse effect, so it is much colder.

The atmosphere is 0.0394 times the pressure of Earth's atmosphere at "sea-level." Most of the moon is elevated and experiences only a third of that, so the highest pressures can be found at the bases of deep canyons, craters, and other terrain formations.

The flat terrain and lack of heat sources has made the thin atmosphere of Izotz very still. Winds rarely exceed a kilometer per hour, and the entire moon is devoid of clouds.
