Forest planets, also sometimes called Earth-type planets, are the only type of planets suitable for life. Scientists of the Polus Corporation believe that forest planets have a common origin with desert planets. Studies have shown that forest planets were able to preserve life on themselves thanks to the remnants of radon water in the soil.

Forest planets are considered one of the smallest planets in the cluster, with their diameter ranging from 1,000 to 1,300 kilometers. The rather small size of these planets, compared to other planets in the cluster, gave researchers reason to believe that forest-type planets are fragments of giant planets that once existed and subsequently collided with each other, of which there are currently very few left in all the galaxies of the cluster - about 10.
After an initial study of the soil of forest planets, geologists found a high content of radon water in it, thanks to which life has still been preserved on planets of this type. A few polyonium deposits have also been found in the soil.
Radon Water
Radon water plays an important role in the creation of electronics for spacecraft, as well as in strengthening their armor. After the shortage of this resource appeared on the galactic market, special wells for the extraction of radon water on an industrial scale began to be actively built on forest planets.
Forest planets are one of the main sources of radon water in the cluster.

The predominant type of landscape on forest planets are rocks and plateaus. Small mountain rivers and reservoirs with still water can often be found.
60-85% of the surface of forest planets is occupied by impenetrable jungles.
