Revona — dune

Revona was the sixth planet of the Canopus system. It has one satellite (Laran).

The planet was so remote that Canopus A appeared as merely a bright first-magnitude star.

Composition

It was composed entirely of helium in different phase states. From upper to lower:

A dense atmosphere of atomic helium covered lays depth of 70,000 meters. Temperatures there varied from 11°K (at the upper helium boundary) to 4.2°K (at the quasi liquid surface). The atmosphere was discovered by Daret of the Planetoscience Council on Arrakis (14390 AG).
Just beneath, the pressure was sufficient to alter the phase state of helium from gaseous to liquid and resulted with a pale blue sea of liquid helium.
At a depth of 3,900 meters, the liquid temperature reacheed 2.6°K and the helium abruptly changed to the zero-viscosity helium 3 as the liquid helium passes through the tri-alpha transition. This transition was only a few meters thick and was characterized by high dynamic turbulence. Helium 3 from that zone was processed by a facility installed on the moon (Laran).
Finally, there was a solid central core of unknown composition, perhaps of helium existing in the supra metallic state. Its existence as deduced by hypo-seismic studies.
