Periodic eruptions of geysers when subsurface ice is melted by volcanic activity. For reference (1 gm/cm3 = 1000 kg/m3). In general, terrestrial planets have a bulk composition that is dominated by rock or iron, and a solid or liquid surface. The pressure is extremely high, allowing iron to say solid. Over 200 moons are also part of the System, orbiting their planets. TRAPPIST-1e, the fourth planet from the star, is in the habitable zone, meaning liquid water could exist on its surface.
