Senecta is a planetary system orbiting a yellow G-class star.  The system lies in the Columba Constellation of the Canopus Region.

Senecta has been located in an isolated part of the Canopus region.  Hidden under a dense nitrogen atmosphere, the system's primary planet has numerous enclosed cites that house the majority of the population, the rest live in orbital stations.


The planet has been considered as terraforming candidate, though it's thick atmosphere would have to be reduced, which is much more complicated than adding to a thin atmosphere.  No government or company has proposed any realistic projects.
