Terra Nostra (novel) Terra Nostra (novel) Terra Nostra is a 1975 novel by the Mexican writer Carlos Fuentes. The narrative covers 20 centuries of European and American culture, and prominently features the construction of El Escorial by Philip II. The title is Latin for "Our earth". The novel received the Xavier Villaurrutia Award in 1976 and the Rómulo Gallegos Prize in 1977. "Terra Nostra", perhaps Fuentes' most ambitious novel, is a "massive, Byzantine work" that tells the story of all Hispanic civilization. Modeled on James Joyce's "Finnegans Wake", "Terra Nostra" shifts unpredictably between the sixteenth century and the twentieth, seeking the roots of
Planet Nine X, Planet Next, or Giant Planet Five." Planet Nine Planet Nine is a hypothetical planet in the outer region of the Solar System. Its gravity could explain the unlikely clustering of orbits for a group of extreme trans-Neptunian objects (eTNOs) that orbit beyond Neptune with average distances greater than 250 AU. These eTNOs tend to have their points of closest approach to the Sun clustered in one direction, and many of their orbits have a similar tilt. This evidence suggests that the gravity from a large undiscovered object is influencing the orbits of the most distant known Solar System objects.
