The surface of ocean planets consists mainly of water. The cold climate of ocean planets often contributes to the formation of glaciers of different sizes, in some cases glaciers can occupy most of the planet.

Research conducted by scientists of the Polus Corporation has shown the presence of a rarefied atmosphere on some planets of this type, which makes these planets suitable for human respiration.

Ocean planets are considered to be the largest ordinary planets in the cluster. Their diameters are in the range of 2100-2500 kilometers.
Despite the apparent simplicity of oceanic planets, their surface water contains radon particles.
Once, as part of one of the geological expeditions, a research probe was able to detect hydrazine deposits at a depth of about 50 kilometers from the surface, after which scientists began developing special wells for the extraction of hydrazine.
Radon Water
The high radon content in the surface water and glaciers of ocean planets makes each of them an almost endless source of radon water, which is one of the main resource in the cluster.
Extraction and purification of radon water on ocean planets is carried out ubiquitously, with the help of automated pumping wells.

Polyonium
For millions of years, huge polyonium deposits have been formed in the depths of ocean planets under the strong atmospheric pressure in underwater glaciers. Over time, due to the difference in density, the ice was gradually pushed to the surface. Together with him, the same polyonium deposits came to the surface, on which today researchers are building mines for the extraction of valuable metal - polyonium.

Hydrazine
The construction of laboratories for the production and purification of natural hydrazine on ocean planets is not a frequent phenomenon, mainly due to the rather low profitability of this type of its production.
However, in some cases, it is mandatory to produce this important resource for the entire cluster even in conditions that are not the most favorable for this.
