Jalan (Wildplanet)

Astronomical facts

Jalan is located in a planetary system which consists of three stars and numerous planets. Most of the system's mass is concentrated in its central star, two smaller stars are going around it in outer orbits without disturbing the inner planets.

Felios

The central star of the system is of spectral class G2, more or less the same size as the Sun.

The Felios Jumpgate is located at coordinates: x = 1350, y = -660, z = 60 (realspace); x = 45, y = -22, z = 2 (hyperspace).

Jalan

The second planet of the system, which happens to have the same distance to it as the Earth from the Sun. It is the only planet in this system that has good conditions for life. Indeed, the first recom explorers who found this planet named it “Wildplanet” for the wilderness that they found.

Jalan has 2/3 of the Earth's mass and gravity, 0.8736 times its diameter. It is circled by two moons, Sisuna takes 10 days to surround Jalan, Luayorna takes 28 days.

Jalan's coordinates in the space grid are: x = 1367, y = -669, z = 60.

Rigiol

A smaller star circling around Felios at 18.58 times the distance of Jalan, with 28 % of Felios's absolute brightness, taking 80.1 years to surround it. Seen from Jalan's surface, Rigiol appears to have 0.0906 % of Felios's brightness in opposition (on the night sky), 0.07304 % in conjunction, when it seems to disappear in Felios's bright light. When it appears in the night sky, which is currently in winter and spring on Jalan's northern hemisphere, it is by far the brightest star.

Smilodanus

The second brightest star on Wildplanet's night sky, at 10300 times the distance between Felios and Jalan. Its absolute brightness flickers around about 0.0052 % of Felios's brightness. As it takes more than a million years for one round, it appears to remain in the same spot in the sky for our lifetimes.

Jalan - the planet

Planetary facts

With 2/3 of the Earth's gravity, Jalan still has a good atmosphere, though the lower air pressure needs some time to get used to it. The air has a higher content of oxygen and inert gases (helium, neon, argon, krypton), but is breathable by Earth's creatures after a period of acclimatization. In fact, an Annyrion creature will not perform any worse on Jalan as the higher content of oxygen makes up for the lower air pressure. As Jalan's axis is only tilted by 7.5 degrees, the seasons are less extreme than on Earth.

The continents

About half of the planet's surface is covered by oceans, with a lower salt content than Annyrion's ocean. There are three continents: One long north/south continent, one C-shaped continent extending to both sides of the equator (Laurasia) and one continent extending from the south pole almost to the equator. All three continents have tall mountains of up to 10000 m height, with huge glaciers. In addition, many islands rise from the oceans, some with impressive mountains as well. The landing places, as well as most settlements, are on Laurasia, whereas the other continents still contain a lot of land only known from satellite photos.

Climate

The climate zones are comparable to Annyrion. A belt of rainforests, savannahs and deserts can be found near the equator. Further to the poles, the lands are largely covered by forests and bushes, getting a good amount of snow in winter the more you get to the north and south. Many areas have numerous lakes and swamps. Enormous masses of ice can be found on both poles.

Geology

Numerous areas have volcanic activity, some of the continents consist of several tectonic plates with the edge going straight through the landscape. The rocks are more colourful than on earth (white, black, yellow, red, green, blue and combinations thereof), and a good number of crystals and precious stones can be found. There are some natural sources of helium.
