Cyros

Cyros is the fourth planet in the Andraco II planetary system. It is the second largest of the system's terrestrial planets and the most highly developed of the inhabited worlds.

Composition and Structure
Cyros is a terrestrial planet, meaning that it has a rocky body, as opposed to the gaseous body of a gas giant or the frozen water body of a glacial planetoid. Of the three terrestrial bodies in the system it is the second largest, though it is the densest and has the strongest magnetic field.

Surface
The surface of Cyros is about 74.2% water, with the remaining split between two terrestrial continents.
