Ven is the giant and fifth planet of Canopus system. It has a pleasant soft pink appearance.

The planet is just under the mass limit that separates planet from star. Together, Ven and its star Canopus account for 99.9% of the total mass and angular momentum of the system.


At its temperature the only atmospheric components that can exist in the gaseous state are hydrogen, helium, and monophospherine. The latter molecular specie is responsible for the soft pink appearance.

Crashing atmospheric pressure coupled with sub Kelvin temperatures preclude the existence of organic life. An extraordinary feature not observed elsewhere in the planetary system is the complete absence of organic molecules. Krai, et al. (AG 15188) showed that monophospherine has strong catalytic properties that can distort and eventually break down the covalent bonds of organic molecules.

The resulting carbon, nitrogen, zeon, and other residue lie kilometers deep on the liquid nitrogen surface.


Almost a star, Ven radiates strongly in the very far infrared and millimeter regions, of the electromagnetic spectrum which is not uniformly distributed over the planet, but from three discrete regions: one in the subpernal zone, and two in the upper mid-temperate band. These are periodic with each region having a different, but constant, period (from 790 μs to 12 ms).

These discrete sources with remote sensing probes have not been successfully located by Arrakian scientist and no reasonable explanation for the natural occurrence of such phenomena has been established. Most felt that the radiating sources were placed deep within the body of the planet by intelligent beings in the remote past — perhaps to provide a navigational guide beacon for deep space vehicles.
