Planet

A planet is a celestial body of (almost) spherical shape orbitting around a star or stars. From Tarris, only the planets of the Twin Suns can be seen, however, planets orbitting different, distant stars are believed to exist by many scholars, arcanists and philosophers, and mentioned in apocryphal texts of different ancient cultures. Since planets move very fast compared to the (seemingly) unmoving background stars, they are often refered to as "wanderers" or "wandering stars". This apparent movement in the sky is, of course, caused by them orbitting around the center of mass of the two Suns.

In the Twin Sun's system, there are eight known planets including Tarris, the third planet from the center. Not all planets are the same: the three outermost known planets have much larger diameters (estimated from their measured distance and apparent size in a telescope) and have colorful surfaces showing bands and stripes made of clouds, called "cloudworlds", as opposed to "stoneworlds" like Tarris. The fifth planet has an unknown composition and a very dark surface or cloud cover.

The planets of the Twin Suns

 * 1) Small and barren world with a crater-covered surface
 * 2) Volcanic planet
 * 3) Tarris
 * 4) This planet appears to have liquid seas, similar to Tarris yet smaller than oceans. Furthermore, much of its surface is seemingly covered in snow.
 * 5) D A R K N E S S
 * 6) Jupiter
 * 7) Saturn
 * 8) Another gas giant
