Solar System

Moons and Rings

There are 5 planets within the Kaimas solar system, which orbit a sun that is 1.42 times the size of ours. Kaimas-2 is the second planet from the sun, 147,946,163 miles away in its closest orbit and 152,447,968 miles in its furthest orbit.

Planet Size

Seasons

Kaimas-2 is 1.015 times the size of Earth with a similar composition based on observed density measurements. The presence of a strong magnetic field surrounding the planet indicates the planet likely has a liquid iron inner core.

Kaimas-2 currently has an axial tilt of 18.4 degrees, but ranges between 14.7 and 20.2 degrees. Compared to Earth, seasonal changes on Kaimas-2 reflect less temperature variation between the hemispheres for summer and winter seasons.

Kaimas-2 has 2 moons and no rings. The larger of the two moons is 0.31 times the size of the planet while the smaller one is 0.22 times as big. The larger moon is closer to the planet at a distance of 322 km away and the smaller moon is located 417 km away.

 

The orbits are near circular and vary on an angle between 6 and 7 degrees from the vertical plane of the poles as the gravity of the Sun, planet and moons interact over the year.

Each day is only 19 hours long. Despite the slight increase in size, the planet rotation is faster and spins in the same direction as Earth. A year is 532 days long, with a month observed by the orbit of the largest moon as 32 days.

 

The moons orbit in a near parallel orbital plane, resulting in very high spring tides when the moons align, with tidal ranges of up to 24m in some seas.

Day and Year Length

The planet's surface is comprised of 8 continents, with a number of volcanic island chains. Land covers 52.08% of the planet’s surface and ocean covers 47.92%.

 

On land there are large numbers of freshwater lakes, with 39.57% of the land mass covered. This means only 31.47% of the planet's surface is terrestrial in nature. The land masses are mostly surrounded by large areas of shallow seas <100m in depth.

Surface Water

Terrain

The planet has 4 very large continents, 3 of which are divided by only a small area of ocean. With large areas of desert covering these land masses, only 19.83% of the total planet's surface is considered habitable. The poles are both covered with land and lakes. 

The surface is pot marked with asteroid impacts of varying sizes, with two large impact sites located on 2 of the 3 large continents. There are a number of mountain ranges and volcanic chains. Most notably a 17km high chain and a 12km high chain due to the collision of tectonic plates. There is a standalone volcano of 14km high on the continent with no asteroid impact. 

Vast ridged plateaus and smaller mountain ranges are found on the other 6 continents. From space there is no visible green areas. The land is reddish-brown, sandy and black-grey.

Atmosphere

The planet's atmosphere is made up of 14.86% oxygen, 0.74% carbon dioxide, 83.14% nitrogen and 1.26% other gases. Due to high concentrations of carbon dioxide in the atmosphere, the planet has an average temperature of 19.8°C.

Climate

Kaimus-2 has a warm and unstable climate creating powerful dust storms, lightning, heavy rainfall and severe droughts. Due to high surface temperatures, Kaimus-2 has no ice on its surface at all.

 

Wind speeds can reach up to 290km/hour, although these are rare. Average storm speeds are typically around 180km/hour. Equatorial regions experience a tropical climate of 30°C, with polar regions at 5 to 10°C from winter to summer months. Some of the desert areas can reach temperatures as high as 65°C.

Signs of Life

On the surface of the planet there are signs of very early planet life, with several small-leaved plant species, mosses and stromatolites in shallow brackish regions.

 

A few species of worms have been found in the soil. More commonly algae and phytoplankton are found in fresh and salt water, with a small number of multi-cellular species no bigger than 7cm in length. Coral can be found in the warm shallow seas.
