Salusa Secundus is a planet of grim ecological and social conditions mostly famous for being the originator of House Corrino and for serving as the imperial prison. The planet suffers from both a rigorous climate and marginal natural resources. The temperature ranges between -45° and 60°C. Its planetary name clearly implies that, like Giedi Prime and Arrakis, Salusa Secundus was named after a star. Secundus (Latin for "second") is a term sometimes used with the lesser of the two components of a binary star. One would expect a "Salusa Prime" somewhere.
