Solanus

Solanus was an planet notable for its indigenous intelligence &mdash; a "thinking ocean". The thought processes of this massive intelligence were carried out by chemical processes in its chemical-rich depths, which formed and reformed various crystalline structures.

Solanus' ocean was highly introverted, and took almost no part in the affairs of the greater Galaxy.

Behind the Scenes
This is obviously a reference to Solaris, a classic sci-fi novel by Stanislaw Lem made into a film by Andrei Tarkovsky, with a more recent remake starring George Clooney. In fact, in the original source, the name "Solanus" is in a different font from the surrounding text, and seems to represent a last-minute correction; probably the original source simply referred to Solaris, which would have placed Star Wars in the future-earth continuity of Lem's book and Tarkovsky's movie.
