Bilbo Colles is named after Bilbo Baggins, a hobbit in J. R. R. Tolkien's fictional world of Middle Earth who appears most prominently in The Hobbit. The name follows a convention that Titanean colles (hills or small knobs) are named after characters in Tolkien's work. The name was formally announced on December 19, 2012.
